PURPOSE. This advisory circular (AC) provides guidance for developing and
managing an airport foreign object debris (FOD) program. In addition, this AC provides
specifications for the equipment used in FOD removal operations.
1.

SCOPE. The program described herein is composed of four main areas: prevention;
detection; removal; and evaluation. Each of the four areas (corresponding to a dedicated chapter
in this AC) contains strategies and practices that can help reduce FOD at airports.

2.

The guidance in this AC is particularly applicable to airport owners and operators, air carrier
station managers, and general aviation operators. Individuals in these positions may then be able
to communicate to apron crews, maintenance technicians, and aircraft servicing personnel the
safety hazards posed by FOD.
The FOD management guidelines presented in this AC are advisory and can be implemented at
the discretion of the airport operator in accordance with the airport operator’s approved Airport
Certification Manual.
CANCELLATION. AC 150/5380-5B, Debris Hazards at Civil Airports, dated 7/5/96, is
canceled.

3.

APPLICATION. The Federal Aviation Administration (FAA) recommends the
guidance and specifications in this Advisory Circular for developing and managing an airport
FOD management program. In general, use of this AC is not mandatory. However, use of this
AC is mandatory for the acquisition of FOD removal equipment through the Airport
Improvement Program (AIP) or the Passenger Facility Charge (PFC) Program. See Grant

CHAPTER 2. INTRODUCTION
2.1.

GENERAL.

The presence of FOD on an airport’s air operations area (AOA) poses a significant threat to the
safety of air travel. FOD has the potential to damage aircraft during critical phases of flight,
which can lead to catastrophic loss of life and airframe, and at the very least increased
maintenance and operating costs. FOD hazards can be reduced, however, through the
implementation of a FOD management program and the effective use of FOD detection and
removal equipment.
2.2.

FOD FUNDAMENTALS.
a. FOD Hazards. FOD can severely injure airport or air carrier personnel or damage

equipment. Types of potential damage include: cutting aircraft tires; being ingested into engines;
or becoming lodged in mechanisms affecting flight operations. Personnel injuries or even death
can occur when jet blast propels FOD through the airport environment at high velocities.
b. Sources of FOD.
(1) FOD comes from many sources, which complicates efforts to maintain safe airfield
operations. FOD can be generated from personnel, airport infrastructure (pavements, lights, and
signs), the environment (wildlife, snow, ice) and the equipment operating on the airfield (aircraft,
airport operations vehicles, maintenance equipment, fueling trucks, other aircraft servicing
equipment, and construction equipment).
(2) FOD can collect both on and below ground support equipment stored or staged on the
airport apron, particularly in apron areas. Jet blast can then blow FOD onto personnel or an
aircraft. Jet blasts can also create runway FOD when an aircraft transitions from a relatively
large-width runway onto a smaller-width taxiway. Outboard engines blow any loose dirt and
materials from the shoulder and infield areas onto the runway. Also, the outboard engines of
four-engine aircraft can move debris from the runway edge and shoulder areas, where it tends to
accumulate, back toward the center of the runway or taxiway.
(3) Helicopters that maneuver over freshly mowed or loose-dirt infield areas can also
move FOD onto runways, taxiways, and ramps. In addition, the rotor wash from a helicopter can
propel lightweight ground support equipment (GSE) or materials staged nearby.
(4) FOD is often more common when airports begin construction activities. FOD may

also be more prevalent in winter conditions, as aging pavement infrastructure may be influenced
by weathering (freeze and thaw cycles) and begin to crack or break apart.
(5) Advisory Circular 150/5200-30, Airport Winter Safety and Operations, contains
specific guidance on using and removing sand to minimize its chances of becoming FOD in
winter weather conditions.

5

AC 150/5210-24

9/302010

(6) Weather can also be the cause of FOD due to movement. For example, wind can

blow dry debris, such as sand or plastic bags, from relatively non-critical areas onto the flight
area. Rain water and drainage can stream mud, pebbles and other small items along the path of
least resistance. Awareness of weather-related sources of FOD movement helps civil engineers
to design barriers and other structures properly.
c. FOD Taxonomy. The exact nature of FOD is also varied. FOD can be composed of any
material and can be of any color and size. In a one year airport study (Information Paper on
French Study on Automatic FOD Detection Systems – Workshop EUROCONTROL, 9-10 June
2008), over 60% of the collected, known FOD items were made of metal, followed by 18% of
the items being made of rubber. Dark-colored items made up nearly 50% of the FOD collected.
Typical FOD includes the following:












aircraft and engine fasteners (nuts, bolts, washers, safety wire, etc.);
aircraft parts (fuel caps, landing gear fragments, oil sticks, metal sheets, trapdoors,
and tire fragments);
mechanics' tools;
catering supplies;
flight line items (nails, personnel badges, pens, pencils, luggage tags, soda cans, etc.);
apron items (paper and plastic debris from catering and freight pallets, luggage parts,
and debris from ramp equipment);
runway and taxiway materials (concrete and asphalt chunks, rubber joint materials,
and paint chips);
construction debris (pieces of wood, stones, fasteners and miscellaneous metal
objects);
plastic and/or polyethylene materials;
natural materials (plant fragments, wildlife and volcanic ash); and
contaminants from winter conditions (snow, ice).

FOD removal operations are not meant to occur when a given area is contaminated with snow or
ice. In such winter conditions, the procedures listed in AC 150/5200-30, Airport Winter Safety
and Operations, are used to clear the AOA surfaces.
2.3

AN AIRPORT FOD MANAGEMENT PROGRAM
a. Airport Regulatory Requirements.
(1) The need for an airport to manage FOD is based on the requirements outlined in 14

CFR Part 139, Certification of Airports. The presence of FOD in the airport environment is
discussed in §139.305.(a).(4), Paved Areas, which states: “Except as provided in paragraph (b) of
this section, mud, dirt, sand, loose aggregate, debris, foreign objects, rubber deposits, and other
contaminants must be removed promptly and as completely as practicable.” In addition, daily
inspections performed at certificated airports (which form the primary means of FOD detection
and removal at some airports) are required under §139.327, Self-Inspection Program. Inspections
are a key component in airport operations, and an effective self-inspection program enables an
airport operator to identify and eliminate unsafe conditions.

9/302010

AC 150/5210-24

(2) Other FAA guidance documents, such as AC 150/5200-18, Airport Safety Self-

Inspection, contain detailed information on the Part 139 inspection process, stating that “The
inspector should continuously check for, and remove any FOD in movement areas, aircraft
parking areas and loading ramps” (reference paragraph 11.g). It should be noted that while Part
139 requirements are mandatory for a holder of a Part 139 Airport Operating Certificate, the
regulation contains many safety practices the FAA recommends for use at all airports.
(3) International standards and practices also discuss the issue of FOD in airports. ICAO
Annex 14, Aerodrome Design and Operations, Chapter 10.2.1 states, “The surfaces of all
movement areas including pavements (runways, taxiways and aprons) and adjacent areas shall be
inspected and their conditions monitored regularly as part of an aerodrome preventive and
corrective maintenance programme with the objective of avoiding and eliminating any loose
objects/debris that might cause damage to aircraft or impair the operation of aircraft systems.”
b. Program Areas.
(1) A successful FOD management programs typically contain four main areas, each

containing significant elements, as outlined below and in Figure 2-1:


Prevention
- Awareness (existence of the FOD program and management support)
- Training and education (implementation of the FOD program)
- Maintenance



Detection
- Operations (manual inspections and use of detection equipment)
- Equipment



Removal
- Equipment
- Operations



Evaluation
- Data collection and analysis
- Continuous improvement (trending, feedback, incident investigation)

CHAPTER 3. FOD PREVENTION
3.1.

AWARENESS.
a. Program Existence and Status.

(1) A first step in implementing a successful FOD management program is making sure
that applicable personnel are aware of the program’s existence. An airport’s FOD management
system should be visible in all aspects of the airport operation. Improvements in FOD safety will
occur most efficiently if all airport personnel are actively encouraged to identify potential FOD
hazards, act to remove observed FOD, and propose solutions to mitigate those hazards. Some
examples of organizational communication are:
(a) FOD seminars;
(b) FOD letters, notices and bulletins;
(c) FOD lessons-learned;
(d) FOD bulletin boards, safety reporting drop boxes, and electronic reporting
through web sites or email; and
(e) A method to exchange safety-related information with other airport operators
through regional offices or professional organizations.
(f) Airport FOD program promotional materials, such as t-shirts, stickers, FOD

disposal cans, and smaller give-away items.
(g) FOD discussion at employee staff meetings.
b. FOD Policy and Management Support.
(1) An effective FOD program must also have the full support of management.

Management’s commitment to FOD prevention should be formally expressed in a statement of
the organization’s FOD policy. The statement will serve to formally establish the FOD
management program. Posting this policy statement in conspicuous locations will help reinforce
the organization’s commitment to FOD prevention and help remind employees of their FOD
management duties. Some key elements of an airport’s FOD policy are:
(a) An outline of the methods and processes that the organization will use to achieve
desired safety outcomes.
(b) The organization’s policy concerning responsibility and accountability.

9

AC 150/5210-24

9/302010

(2) The FOD Program Manager.
(a) Airport operators should designate an accountable staff member to manage the
airport’s FOD programs and issues. This designated individual can be a dedicated FOD manager
or can have other duties (e.g., operations manger, safety manager, etc.).
(b) The responsibilities of the FOD Manager should be clearly defined along the

identified lines of communication within the organization. Additionally, the FOD manager
should be allowed to report to the highest levels of management (e.g. airport president, chief
executive officer (CEO), etc.) to assure appropriate consideration of all reports,
recommendations, and issues.
(c) The FOD manager should regularly communicate the status of the FOD program

to airport staff and ensure that lessons learned from hazardous occurrence investigations and case
history or experiences, both internally and from other organizations, are distributed widely. An
open line of communication should always be available between the FOD Manager and the
airport/air carrier staff.
(d) An expanded discussion of the suggested duties and responsibilities of a FOD
manager are provided in Appendix A.
(3) The FOD Committee.
(a) A number of airports of varying sizes and complexities have found it helpful to
establish a FOD committee. Note: The level of authority or power of the FOD committee will
be different for each airport, as it is set by the airport’s executive management.
(b) The composition of the committee is under the airport’s discretion, but typical

committee members include those stakeholders with a direct relationship to FOD (such as those
in a position to produce or remove FOD), including: tenant representatives, air carriers, airport
operations and public safety staff, and contractor representatives, etc. The FOD manager would
typically chair the committee.
(c) One of the most important functions of the FOD committee is to serve as a
resource for the FOD manager. In addition, the determination of potentially hazardous FOD
situations can be performed by the FOD committee, as well as performing an evaluation of
collected FOD data.
c. Safety Culture. An effective FOD management program requires more than the

implementation of rules and procedures to be followed. It requires the support of management to
establish the attitude, decisions, and methods of operation at the policy-making level that
demonstrate the organizations priority to safety. In effective safety cultures, there are clear
reporting lines, clearly defined duties and well understood procedures. Personnel fully
understand their responsibilities and know what to report, to whom and when. Though it is an
intangible aspect of a safety program, proper personal attitudes and corporate commitment
enable or facilitate the elimination of unsafe acts and conditions that are the precursors to
accidents and incidents.

10

3.2.

AC 150/5210-24

TRAINING AND EDUCATION.

a. Audience. Each individual with access to the AOA should understand their role in the
prevention of FOD. These personnel include: airport operations; construction; aircraft
maintenance and permanent/seasonal servicing staff (e.g. catering, fuel, cabin cleaning, baggage
and cargo handling, waste disposal, etc.), and any other contractors. A formal
orientation/indoctrination program familiarizing new employees with safety, security,
communications, and vehicle operations should include FOD management training. This
training can supplement the general FOD awareness incorporated into the driver training
curriculum (or training for apron walking privileges) already in place at many airports.
b. Features. The FOD manager provides current information and continual training

relating to FOD issues relevant to the specific operation of the airport. The provision of
appropriate training to all staff, regardless of their level in the organization, is an indication of
management’s commitment to an effective FOD management program. FOD training and
education programs typically contain the following features:
(1) A documented process to identify training requirements;
(2) A validation process that measures the effectiveness of training;
(3) Recurrent training and education (to help maintain awareness);
(4) Human (and organizational) factors.
c. Training Objectives. The primary objectives of the FOD training program will be to

increase employee awareness of the causes and effects of FOD damage and to promote active
employee participation in eliminating FOD during performance of daily work routines. The
FOD manager should emphasize FOD management through employee motivational programs as
well as by conducting training courses to emphasize FOD prevention through efficient design,
product discipline, maintenance, and flight line activities. The following subject matter should
be included, as applicable, in the FOD manager’s FOD prevention program:
(1) Overview of the FOD management program in place at the airport;
(2) Safety of personnel and air carrier passengers;
(3) Causes and principal contributing factors of FOD;
(4) The consequences of ignoring FOD, and/or, the incentives of preventing FOD;
(5) Practicing clean-as-you-go work habits, and the general cleanliness and inspection

standards of work areas (including the apron and AOA);
(6) Proper care, use, and stowage of material and component or equipment items used

around aircraft while in maintenance or on airport surfaces;

11

AC 150/5210-24

9/302010

(7) Control of debris in the performance of work assignments (e.g. loose items associated

with luggage, ramp equipment, and construction materials);
(8) Control over personal items and equipment;
(9) Proper control/accountability and care of tools and hardware;
(10)

Requirements and procedures for regular inspection and cleaning of aircraft and

apron areas;
(11)

How to report FOD incidents or potential incidents;

(12)

Continual vigilance for potential sources of hazardous foreign objects;

(13)
FOD Detection procedures, including the proper use of detection technologies (if
applicable); and
(14)

FOD Removal procedures.

d. Training Documentation. Training requirements and activities should be documented

for each area of activity within the organization. To the extent possible, a training file should be
developed for each employee, including management, to assist in identifying and tracking
employee training, training requirements, and verifying that the personnel have received the
planned training. Any training program should be adapted to fit the needs and complexity of the
airport in question. At certificated airports, this is already being done for training required by 14
CFR Part 139, Certification of Airports.
3.3.

MAINTENANCE PROGRAMS.

a. An airport’s FOD prevention program should be tailored to mitigate the particular actions
and activities that generate FOD. A few examples of these activities include:
(1) Aircraft Servicing. Air carriers and airport tenants generate much of the FOD found
in the airport apron, service roads, baggage makeup areas, and areas near flight kitchens.
Agreements between air carriers and their support organizations should specify which of the
parties are responsible for cleaning various areas. In addition, the airport can help these
organizations to establish procedures to inspect GSE for signs of wear and tear that can lead to
FOD hazards. Procedures to inspect the baggage loading and unloading areas every time an
aircraft is serviced can also be helpful, as luggage items (such as baggage wheels, zippers, and
accessories) are common FOD items found in the airport apron.
(2) Aircraft Maintenance. Account for and dispose of nuts, bolts, washers, safety wire,

etc. Account for hand tools used in repair jobs. Aids in the control of these items include
checklists, shadow boards, and cut out tool tray liners. All items should be contained in a spill
proof tote bag, tray or toolbox.
(3) Air Cargo. In an air cargo area, there is a high potential for blowing debris such as

cargo strapping and plastic. Establish procedures to contain such debris, possibly by installing

12

9/302010

AC 150/5210-24

(and monitoring) fencing where appropriate. Of course, FOD trapped by such fences should be
removed regularly.
(4) Construction.
(a) Both airside and landside construction activities, as well as scheduled
maintenance, should be communicated to airports users as early as possible. Specific FOD
prevention procedures should be established and employed for each construction project. These
procedures should be based on the proximity of construction activities to operational areas but in
general should stress containment and regular cleanup of construction debris. Airport
preconstruction planning should include a means for controlling and containing FOD generated
by the construction. This is especially true in high-wind environments where debris is more
likely to become airborne. For additional guidance on airport actions during construction
activities, please reference AC 150/5370-2, Operational Safety on Airports During Construction.
(b) The designated routes of construction vehicles on the AOA should be examined,
so as to avoid or minimize crossings of critical areas of aircraft operations. If high-risk crossings
cannot be avoided, subsequent provisions such as an increased frequency of FOD inspections
could be implemented. Airport operators should ensure that these provisions are incorporated
into their FAA-approved Safety During Construction Plan.
(c) Contractors must fully understand the requirements and penalties incorporated in
their contracts regarding the control and removal of FOD. To help ensure this occurs, airport
operators may consider drafting standard “FOD Control and Clean-up” related language for all
construction projects taking place within the AOA. The standard and project-specific FOD
provisions could then be included into the contract documents for AOA construction projects.
These items may include:






Requiring contractors to cover all loads;
Requiring contractor to secure any lose items that could easily be blown;
Specifying whether any mechanical FOD removal devices will be required;
Specifying how monitoring for FOD hazards will be done; and
Requirements for inspecting tires prior to traversing areas where aircraft are located.

(5) Airfield Maintenance Operations.
(a) Mowing and other maintenance operations routinely disturb the vegetation and
soil in areas adjacent to areas traveled by aircraft. Establish procedures to remove debris such as
the use of an assigned airfield sweeper or personnel on foot using shovels to repair vegetation
and soil.
(b) Airfield lighting, pavement, and marking maintenance operations generate
concrete/asphalt debris as well as increase the potential for dropped repair parts, tools, and other
items stored on the maintenance vehicles. Corrective procedures should include the use of
airfield sweepers and inspection of the work site after the procedures are completed.

13

AC 150/5210-24

9/302010

(6) Pavements. Asphalt and concrete pavements may be the most common source of

FOD on an airport. Therefore, effective pavement maintenance practices are critical to the
mitigation of FOD. The FAA has developed extensive resources for pavement maintenance. For
further information on this topic, please refer to AC 150/5380-6, Guidelines and Procedures for
Maintenance of Airport Pavements, or visit http://www.faa.gov.

CHAPTER 4. FOD DETECTION
4.1.

GENERAL.
a. While proper FOD awareness is fundamental for any successful FOD program, the act of

detecting FOD is one of the critical FOD operations that occur at an airport. This process
involves not only the identification of potential FOD causes and locations, but also the timely
detection of any FOD on airport surfaces. Whether detection occurs manually, through regular
inspections, as a result of pilot reports, or through the use of advanced detection technologies, the
outcome is equally important.
b. Runway Closures.
(1) A highly sensitive question involved in the use of continuously operating FOD

detection technologies arises once an object is detected. If the location or characteristics of the
FOD present no immediate safety hazard the object should be removed as soon as the operational
schedule permits. If the location or characteristics of the FOD present an immediate safety
hazard, provisions in the FOD management program should clearly indicate that a hazard exists
and allow for an airport supervisor to take action and temporarily cease operations and, in the
case of aircraft or airport equipment source of the FOD, notify the equipment operator. This is
an appropriate issue, for example, for an airport’s FOD committee to study and provide further
guidance to airport management and operations staff.
(2) On March 17, 2009, the FAA issued CertAlert 09-06, Closing active runway for FOD

checks increases safe operations. In this advisory notice, the FAA stated that although not all
types of FOD will necessitate an immediate runway closure, quick and decisive action should be
taken, in all cases, to assess the threat posed by reported FOD. The FAA recommends that
airports work closely with their Airport Traffic Control facilities in establishing procedures for
handling such matters. For those interested, local FAA Airport District or Regional Offices can
provide sample Letters of Agreement that address these types of situations and that have been
successfully implemented at high activity air carrier airports.
4.2.

FOD RISK ASSESSMENT.

A FOD risk assessment enables an airport to determine where unsafe FOD conditions exist.
However, since the risk assessment process is an integral part of an airport’s Safety Management
System (SMS) program, and the FAA does not require airports to have an SMS program, the risk
assessment process will not be discussed at this time. If, or when, airports are required to have
an SMS program in the future, this AC will be updated to reflect the appropriate risk assessment
procedures.
4.3.

FOD DETECTION OPERATIONS

a. Inspection Areas. While detailed inspection guidance is provided in AC 150/5200-18,
Airport Safety Self-Inspection, additional information can be helpful for airport personnel
conducting FOD inspections. The following areas and operations are typically prone to having
FOD:

15

AC 150/5210-24

9/302010

(1) Movement Areas (runways and taxiways).
(a) The portion of the runway used by aircraft to take off is where departing aircraft
are most susceptible to FOD damage.
(b) Deteriorating or neglected pavement can exhibit spalling or cracks. For example,
pieces of concrete can break loose from pavements or FOD can develop from fatigue corner
cracks and airfield markings. FOD associated with building materials, debris falling from
construction vehicles or blown from the airport apron onto aircraft maneuvering areas. Broken
pieces of pavement can collect at the edge of the airport apron and be carried onto the aircraft
maneuvering area by the tires of vehicular GSE.
(c) Service roads that cross taxiways should be monitored closely to prevent the

vehicles using these roads from moving FOD onto the taxiways (especially in the case of
construction operations, as addressed in the airport’s Safety During Construction Plan).
(d) Shoulders. Unpaved areas adjacent to pavement should be stabilized to prevent
FOD. (AC 150/5300-13, Airport Design, provides further guidance in the construction of
stabilized shoulders.)
(e) Pavement Joints. Special attention should be paid to the cleaning of cracks and
pavement joints as tests have shown that these are the main sources of foreign objects which are
ingested.
(f) Turf Areas. Turf grass and ditches collect and hold large amounts of light debris

such as paper, cardboard, plastic, and various containers that trash often originate in terminal
aprons, cargo ramps, and hangar ramps. This trash can blow back into areas traveled by aircraft
unless collected in a timely manner.
(g) Fence-lines. Fences can collect trash on windy days. This FOD should be

collected before the wind increases or shifts direction and the trash blows back on to areas
traveled by aircraft.
(2) Airport Apron. Anywhere on the aircraft apron where ground vehicles operate.
(3) Aircraft Servicing Operations.
(a) Refueling, catering, cabin cleaning, and baggage and cargo handling can produce

broken materials.
(b) Baggage pieces, including bag tags and wheels, can break off luggage and either

fall onto the apron or collect in the door sill. Items collected in the door sill can damage the door
or prevent it from properly closing. They can also be knocked out of the sills and onto the apron
at the next station.
(c) Other areas where FOD is likely to collect include the ground at both ends of the

conveyor, and the area between the baggage cart and the conveyor belt.

16

9/302010

AC 150/5210-24

(4) Air Cargo Operations.
(a) High potential for blowing debris such as plastic cargo wrappers.
(b) Fencing used to contain debris should be cleaned regularly.
(5) Construction Operations.
(a) The proximity of construction activities to operational areas presents a risk of

debris.
(b) Regular and thorough cleaning of the construction site, including the construction
haul routes, is expected. These provisions are typically outlined in local rules and pre-existing
agreements, such as the construction safety plan. Particular attention should be paid to
construction vehicle routes that cross or are adjacent to active pavements.
(6) Aircraft Maintenance Activities.
(a) These activities, which may be performed on the apron, require a variety of small

objects, such as rivets, safety wire, and bolts that become FOD when they are inadvertently left
behind.
(b) All tools should be accounted for as a matter of practice. Aids in the control of
these items include checklists, shadow boards, and cut out tool tray liners. For more information
on an effective tool control program, please see NAS 412, Tool Accountability.
(7) Other activities. All vehicles should be driven on clean, paved surfaces when
possible. If a vehicle must be driven on unpaved surfaces, the operator should check the vehicle
tires for foreign objects immediately after returning to the pavement.
b. Methods and Techniques.
(1) The FAA and ICAO require a daily, daylight inspection of aircraft operating areas.
Operational areas must be inspected at least once each day, with additional inspections being
made in construction areas and immediately after any aircraft or ground vehicle accident or
incident or any spill of material which may cause slippery conditions. In addition to performing
these inspections at the beginning of the day or shift, personnel in the AOA should practice a
clean-as-you-go technique of looking for FOD during their normal shifts in the course of their
regular duties. Inspections occurring at night, taking place after the runway is closed or before
the runway is opened, also occur frequently. During night time inspections, personnel and
vehicles should be equipped with additional lights/lighting systems to better detect FOD.
(2) Detection Technologies.
(a) Recent technological developments have greatly expanded the capabilities of

FOD detection through automation. Advanced technologies are now available for improved
FOD detection, including capabilities for continuous detection on runways and other aircraft
movement areas and mobile detection devices to supplement the capabilities of airport personnel.

17

AC 150/5210-24

9/302010

If an airport chooses to implement these new FOD detection technologies, they should ensure
that the personnel monitoring these systems either have the authority (or the ability to quickly
contact those in authority) to take appropriate and timely action if FOD is detected. Please see
AC 150/5220-24, Airport FOD Detection Equipment, for more detailed information on the
performance capabilities of advanced FOD detection technologies.
(b) FOD Detection Notification. The airport operator and air carriers have
considerable flexibility in terms of how to implement continuous detection systems at the airport.
The user interface may be located in the airport’s operation or maintenance center, or it may be
located in the airport traffic control (ATC) tower. Regardless of the configuration, an airport
will determine the most efficient way to notify airport/air carrier personnel to remove the
detected FOD, as well as the ATC staff to divert aircraft if a significant risk is presented.
(c) Wildlife. There are currently no uniform standards or procedures for the

detection of wildlife on an airport. However, anecdotal evidence suggest that dead wildlife are
more appropriately handled as a component of a FOD management program, while live wildlife
are a component of a wildlife hazard management program. An overlap of these two programs
therefore occurs whenever wildlife are struck by aircraft and/or their remains serve as an
attractant to other wildlife. In addition, elements of certain wildlife programs can create FOD,
e.g. the introduction of cracker shell casings. Certificated airports (under 14 CFR Part 139) and
airports that have a Wildlife Hazard Assessment Plan may therefore need to review their plan as
it relates to the airport’s FOD program.
(3) Manual Detection.
(a) When conducting an inspection on a runway, inspection techniques will be
determined by runway availability and type of operation. Ongoing construction requires more
frequent inspections. It may even be necessary to assign dedicated personnel to continually
inspect for FOD during major construction activities. As part of the FOD management program,
the FOD manager may find it appropriate to reach out to air carriers and flight crews to leverage
the airport’s current FOD management efforts. For example, flight crews could be asked to
report to ATC and station operations any FOD they observe on runways and taxiways. Air
carrier and aircraft handling agents may also be asked to designate individuals to inspect apron
areas prior to aircraft movement to and from the gate.
(b) A runway inspection will involve passage along the length of the runway to
observe and remove FOD. The most effective method involves two or more passages to reduce
the width of the inspection zone. When there is time to do only one pass on the runway,
inspection personnel, whenever practical, should drive in the opposite direction that aircraft are
landing on the runway with high intensity flashing beacon and headlights on at all times. This
practice will enable self-inspection personnel to see approaching aircraft and improve visibility
of the vehicle to pilots. Inspection personnel should also drive the stub taxiways between the
runway and parallel taxiway because these areas are commonly overlooked.
(c) Encouraging the participation of airport tenants in inspections will reinforce the

concept that FOD prevention is a team effort and demonstrate the airport operator's commitment
to a debris-free environment. As such, air carrier personnel, when feasible, should join the

18

9/302010

AC 150/5210-24

airport staff in daily movement area inspections. This practice helps increase familiarity with
local airfield conditions, and promotes effective communication between the airport and air
carriers. The placement of convenient and conspicuous FOD containers (as described in
Paragraph 5.2 of this AC) is a helpful reminder of the need to be vigilant in preventing the
occurrence of FOD.
(i) An effective and clever operation currently in place at airports is the
promotion of all-hands “FOD walks.” These walks are typically conducted as part of an airport’s
FOD management campaign. Walks involve the coordination and invitation of airport and air
carrier staff (e.g. ground handling agents, air carriers, Aircraft Rescue and Fire Fighting (ARFF)
and apron personnel), external partners, and other community volunteers to participate in
manually collecting airport FOD. These events can be promoted with offering food and water to
participants, and various prizes (i.e. airport clothing) to those who collect the most FOD. Of
note, during this type of event, identifying the location and origin of FOD (for data analysis and
evaluation) is not always possible.
(d) For further guidance on the performance of airport inspections, please see AC
150/5200-18, Airport Safety Self-Inspection.
4.4.

FOD DETECTION EQUIPMENT.

The standards and specifications found in AC 150/5220 24, Airport Foreign Object Debris
(FOD) Detection Equipment, represent the FAA guidance for the evaluation and procurement of
FOD detection systems.

CHAPTER 5. FOD REMOVAL
5.1.

BACKGROUND.

Once FOD is detected, the next major operation of a FOD management program will occur:
removing FOD from the airport environment. The most effective resource for FOD removal is
the use of FOD removal equipment, especially in areas where FOD can be expected, such as near
areas of construction. For removal of an isolated FOD object detected on a runway, manual
removal will be the most efficient. Although specialized equipment is available and highly
suited to some airport operations, FOD removal methodologies and technologies are available
for all airports.
5.2.

EQUIPMENT CHARACTERISTICS.

This AC does not limit the equipment that airports may use for FOD removal. Currently
available removal equipment can be categorized into two types: mechanical and nonmechanical. Additionally, the category of storage systems (FOD containers) is also of
fundamental importance.
a. Mechanical Systems. These technologies use powered devices in mechanical systems
that remove or retrieve FOD items and contain retrieved FOD for proper disposition. Equipment
in this category varies in size, and is found in sizes from small push units to large area systems
that are truck mounted. Types of mechanical removal systems include:
(1) Power Sweepers, including tow-behind bristle trailers. The sweeper removes debris

from cracks and pavement joints, and is typically used in all areas of the AOA including areas
where GSE are staged. NOTE: For all brush systems, operators are cautioned that bristles can
detach from brooms and produce a FOD source. Brushes made with metal bristles or spines are
not recommended to be used for FOD removal purposes. Plastic or combination plastic/metal
bristles may be appropriate, but the user should consult the equipment manufacturer for specific
recommendations. Regardless of the equipment used, a thorough check of the pavement should
be conducted at the conclusion of the sweeping procedure.
(2) Vacuum Systems. These systems perform FOD removal functions similar to the
power sweepers described above, but use air flow as the primary means of object retrieval. The
systems may also perform in conjunction with mechanical brooms or other recirculating air units.
(3) Jet Air Blowers. These systems move FOD and other debris by directing a stream of

high velocity air towards the pavement surface. When used in the airport environment, it is
recommended that these systems incorporate a debris collection mechanism so that FOD will not
simply be relocated to another area in the AOA.
b. Non-Mechanical Systems.
(1) Friction Mat Sweepers. A rectangular assembly towed behind a vehicle that
employs a series of bristle brushes and friction to sweep FOD into sets of capture scoops, which
are covered by a retaining mesh to hold collected debris.

21

AC 150/5210-24

9/302010

(2) Magnetic Bars (attached to vehicles). These bars can be suspended beneath tugs

and trucks to pick up metallic material. However, the bars should be cleaned regularly to prevent
them from dropping the collected debris. Vehicles operation in the AOA should be inspected
periodically to ensure that they have no loose items that can fall off. Common magnetic
materials include ceramic, rare earth, and alnico metals. Conversely, magnetic bars are not able
to pick up the following types of common FOD materials: titanium and aluminum alloys, some
stainless steels, and plastics.
(3) Rumble strips (also “FOD Shakers”). Long devices, which are 10 to 15 ft (3 to

4.60 m) long, that are positioned on the pavement to dislodge FOD from vehicles that drive over
them. While these devices may have been used in the past, they are no longer a widely accepted
FOD removal system. Their effectiveness at removing debris from tires or vehicle
undercarriages is negligible, and the equipment can generate its own FOD if not cleaned out
regularly. The current best practice for removing FOD from tires is to stop a vehicle at a
designated checkpoint, perform a visual inspection, and then use a hand tool to manually remove
detected debris.
c. Storage Systems (FOD Containers).
(1) Designated FOD containers should be conspicuously placed at all gates for the

collection of debris. The containers should be well marked, properly secured, and emptied
frequently to prevent them from overflowing and becoming a source of FOD themselves. In
addition, airport personnel can wear waist pouches to collect debris.
(2) “Closed-type” containers are preferable, given the opportunity for wind to dislodge

the container contents. Consequently, “open-type” containers are not advised. Airport operators
should ensure that FOD containers do not blow over during periods of high winds. This can be
accomplished by using heavy trash cans or securing the containers to the ground with a tether or
a weight. FOD containers should also have placards stating that hazardous materials may not be
deposited in them.
(3) Locations. Suggested locations include: near all entry points to the AOA, in
hangars, in aircraft tie-down and aircraft maintenance areas, and at each aircraft gate or baggage
area. Central or well-known storage locations increase the likelihood that collected debris will
be deposited by personnel.
(4) Other means for containing FOD include: wind barriers and netting to restrict
movement of airborne FOD; fencing to prevent animals from entering the airfield; and wellmaintained paved surfaces. If damaged pavement cannot be repaired immediately, airport
operators should make arrangements for aircraft to take an alternate route.
(5) Evaluating the debris collected in containers and pouches can reveal its sources and
indicate where personnel and equipment should be deployed for more effective control. Chapter
six of this AC will provide more information on this practice.

AC 150/5210-24

PERFORMANCE.

a. Operational Standards. Unless otherwise specified, the following standards apply only
to “mechanical” FOD removal systems.
(1) Operational Speeds. The minimum speeds that FOD removal equipment should
operate and collect 90% of FOD (based on the “test/validation objects described in paragraph
5.3.b) is 15 mph (25 km/h). Maximum speeds are limited by airport operations regulations.
(Mechanical and non-mechanical systems)
(2) Collection Path.
(a) The minimum path for a removal system used during airport operations is 60 in
(150 cm) wide.
(b) Systems that are used on the airport apron or designed to be mounted on existing
airport operations vehicles must have a minimum path 40 in (100 cm) wide.
(c) Magnets must be at least 36 in (90 cm) long and 4 in (10 cm) wide. (Mechanical
and non-mechanical systems)
(3) Retention / Hopper Capacity.
(a) The minimum usable capacity of a power sweeper used during airport operations
is 40 cu ft (1 cu m).
(b) For systems mounted on airport operations vehicles, the volume of the truck bed
will represent the retention capacity.
b. Testing / Validation.
(1) All FOD removal equipment must be able to demonstrate the ability to collect 90

percent of the items listed in paragraph below, when they are placed in a 10 ft x 10 ft (3 m x 3 m)
square on the pavement surface, on one pass of the equipment at a minimum speed of 15 mph
(25 km/h). Where specific dimensions and weights are not provided, the purchaser will
determine the object properties most characteristic of those found on their airport.
(2) Test / Validation Objects.

-

A metal cylinder measuring 1.2 in (3.1 cm) high and 1.5 in (3.8 cm) in
diameter (both ferrous (i.e., magnetic) or non-ferrous metals are acceptable),
A sphere, measuring 1.7 in (4.3 cm) in diameter (i.e., a standard size golf
ball),
A “chunk” of asphalt or concrete,
Any portion of a runway light fixture (in-pavement or edge light),
A wrench (up to 8 in. (20 cm) in length),
A socket (at least 2 in. (5 cm) in length),
A piece of rubber from an aircraft tire,

23

AC 150/5210-24

9/302010

-

A distorted metal strip (up to 8 in. (20 cm) in length),
Fuel cap (aircraft or automotive),
Lug nut,
Hydraulic line (from aircraft or GSE, up to 8 in. (20 cm) in length), and
Aircraft fasteners and safety wire.

(3) Further testing requirements are contained in Appendix B, Section B.3, of this

document.
c. Additional Standards. Additional FOD removal system standards are located in
Appendix C.
5.4.

REMOVAL OPERATIONS.
a. Individuals responsible for FOD removal operations should have direct responsibility for

the safety of those operations and should be given the resources to implement the necessary
controls.
b. The majority of FOD removal operations are performed in conjunction with the detection
operations described in paragraph 4.2 of this AC. While the exact actions are specific to each
airport, the following two examples of FOD removal operations from a high activity air carrier
airport in the U.S. represent the successful implementation of FOD removal equipment:
(1) Assigning an airfield sweeper(s) to work with maintenance crews and/or respond as

required to reports of FOD.
(2) Deploying a maintenance employee on a small all-terrain vehicle with a litter stick

and garbage bags to pick up trash in grassy areas and fence-lines. This operation is intended to
pick up debris before it returns to the pavement areas. In one year, over 2,898 bags of trash were
collected using this method.
c. The equipment described in this chapter may be used singularly or in combination. In

either case, FOD managers are cautioned that personnel using particular FOD removal
equipment may become complacent and completely rely on the equipment to remove all pieces
of FOD in their area of operation. Personnel must be constantly aware of the performance of
their equipment, and should regularly check to make sure visually detected FOD is in fact
collected by their equipment during FOD removal operations.

24

9/302010

AC 150/5210-24

CHAPTER 6. FOD EVALUATION
6.1.

DATA COLLECTION AND ANALYSIS.
a. A critical part of any FOD management system is the information available for problem

assessment and management program design. Although anecdotal information on FOD collected
at airports is available, no comprehensive assessment of FOD types and sources is possible
unless a comprehensive data collection and analysis scheme is in place.
b. Documentation. The FOD manager will ultimately determine the documentation
guidelines in a FOD management program. Certain small items, such as plastic wrappers or
baggage tags, may simply warrant efficient collection and disposal. A consistent trend of small
items, such as those coming from a particular entity or operation, or particularly large or
hazardous FOD, may require detailed documentation for effective analysis and prevention
efforts. It is recommended that airport personnel collect the following information, to the extent
practicable, whenever FOD is collected:
(1)

How the FOD object was detected

(2)

Date and time of FOD detection and retrieval

(3)

Description of FOD retrieved (category, size, color), and/or image (if available)

(4)

Location of FOD object (coordinates and reference to the AOA location)

(5)

Possible source

(6)

Name of personnel detecting / investigating FOD item

(7)

Airport operations and weather data during the FOD detection event

c. Reporting.
(1) Depending on the volume or significance of collected FOD, the FOD manager may
decide that it is necessary to designate and train certain personnel to collect, tag, store, and report
on the collected FOD for future data analysis efforts. An additional communication procedure
may also need to be established, so that the person who first collects the FOD will notify the
person responsible for reporting the FOD. In any case, a well-defined reporting procedure is an
important aspect of any FOD management program.
(2) The FOD management program should include a visible FOD reporting system

supported by management. The reporting system should permit feedback from personnel
regarding FOD hazards and other safety-related concerns. The FOD management system should
use this information to identify and address operational or administrative deficiencies.
(3) Depending on the potential hazard of FOD collected, a reoccurrence of FOD from the

same source, and the personnel available at an airport, the FOD management program may

25

AC 150/5210-24

9/302010

contain provisions to notify the FOD source of a FOD occurrence. Operational experience from
at least one airport has shown that notifying the source of FOD helped to correct the underlying
safety deficiencies that caused multiple FOD events.
d. Investigation. It is recommended that major FOD incidents (as determined or classified
by the airport operator) are investigated by the FOD manager or other appropriate airport
personnel. An investigation should try to determine the source of FOD and damage caused.
When the investigation is completed and necessary corrective action has been implemented in
accordance with the FOD management plan, final disposition of the incident should be entered
into the airport’s FOD reporting system.
e. Database. It is important that the organization maintain a record of the measures taken

to fulfill the objectives of the FOD management system. These records may be required in the
event of a formal investigation of an accident or serious incident, and can also be used to identify
any trends, repeats, unusual conditions, etc., in order for corrective action to be initiated.
Records can also provide quantitative data for future risk assessments, support the assessment of
system operational history and assure operational capabilities. The disposition of reported
information will be based on the airport’s FOD management program specifications and support
§139.327 certification. All records should be maintained in sufficient detail for a period of at
least 2 years to ensure traceability of all significant safety-related decisions. The FAA is
currently developing the framework for a national FOD database. Airport’s collecting highquality FOD data (showing at least the type, location, and source), are encouraged to submit their
data to FAA once the national database is in operation.
6.2.

CONTINUOUS PROGRAM IMPROVEMENT.
a. Safety performance monitoring validates the FOD management program, confirming the

organization’s safety objectives. Through regular review and evaluation, management can
pursue continuous improvements in FOD management and may revise safety objectives,
policies, procedures, and training programs to ensure that the FOD management program
remains effective and relevant to the organization’s operation.
b. The FOD Manager, in assessing the effectiveness of the FOD management program,

should work with the persons that have direct responsibility for analyzing hazards, identifying
control measures derived from that analysis, and ensuring those measures are effective.
c. Program Evaluation. These evaluations provide a means for systematically assessing
how well the organization is meeting its FOD management objectives. The evaluation provides
a review of existing conditions and results in recommendations for enhanced debris control.
Management may choose to have an external organization evaluate the system (e.g., by a
consultant or another airport operator), or choose to perform the evaluation using airport/air
carrier staff. In addition to supporting the airport operator’s existing responsibilities for selfinspection and correction of discrepancies under 14 CFR Part 139, an effective airport FOD
management program evaluation should:

26

9/302010

AC 150/5210-24

(1) Systematically review the effectiveness of existing FOD-management procedures

used by airport and air carrier personnel, including all available feedback from daily selfinspections, assessments, reports, and other safety audits:
(2) Verify that the airport is meeting identified performance indicators and targets;
(3) Solicit input through a FOD system;
(4) Communicate findings to staff and implement agreed-upon corrective procedures,
mitigation strategies, and enhanced training programs; and
(5) Promote safety in the overall operation of the airport by improving coordination

between airport staff, air carrier personnel, and airport tenants.

Appendix A

APPENDIX A: SUGGESTED DUTIES AND RESPONSIBILITIES OF THE FOD
MANAGER
The information presented in this section represents only one of many potential approaches to
designating the duties and responsibilities of a FOD Manager. Airports should select/modify any
items that would be most appropriate for their situation when developing their FOD program.
A.1. GENERAL. Where appropriate, the airport operator should designate a FOD
Manager(s) that will develop and implement plans and programs to prevent, detect, and remove
FOD on an airport. The FOD Program Manager may be a dedicated position, but will more
likely than not be an additional role assigned to someone currently serving in the airport
operations staff. The FOD Manager(s) should be appointed by an Airport executive, or
executive of the commercial business operating at the airport, and should have sufficient
authority and organizational freedom to identify and implement FOD preventive measures
whenever and wherever required.
A.2.

THE FOD MANAGER should:

a. Review and assess the airport’s FOD management program and make necessary
revisions.
b. Conduct scheduled and unscheduled evaluations/inspections of work areas to assess the

effectiveness of the FOD management program.
c. Assure implementation of corrective actions for FOD prevention.
d. Assure that FOD incidents are thoroughly investigated and that incident reports are
accomplished as specified in paragraph 6.1 of this AC.
e. Assure that causes of FOD incidents are thoroughly analyzed to identify corrective
measures.
f. Notify affected contractor/tenant organizations and personnel of unique FOD prevention
requirements.
g. Develop techniques and assign responsibilities for publication of special FOD prevention
instructions.
h. Review results of the FOD incident investigations and evaluate the adequacy of

corrective actions.
Evaluate the amount and kind of foreign objects found and how they were found (e.g.
during daily inspections, by pilots, airport operations staff, etc.).
i.

Review and approve FOD prevention training curricula, designate training personnel, and
assure that airport/contractor/tenant personnel receive required training.
j.

29

AC 150/5210-24
Appendix A

k. Assure that written procedures provide for adequate records attesting to the current status

and adequacy of the FOD management program.
