| Foreign object debris (FOD) at airports includes any object found in an inappropriate location that -- as a result of being in that location -- can damage equipment or injure airplane or airport personnel. The resulting damage is estimated to cost the aerospace industry $4 billion a year. Airports, airlines, and airport tenants can reduce this cost by taking steps to prevent airport FOD. FOD includes a wide range of material, including loose hardware, pavement fragments, catering supplies, building materials, rocks, sand, pieces of luggage, and even wildlife. FOD is found at terminal gates, cargo aprons, taxiways, runways, and run-up pads. It causes damage through direct contact with airplanes, such as by cutting airplane tires or being ingested into engines, or as a result of being thrown by jet blast and damaging airplanes or injuring people.
Effective training should stress safety to personnel and passengers, the hazards to equipment, the direct costs associated with FOD damage, and the indirect costs associated with flight delays and rescheduling. It should also include procedures for removing and eliminating FOD at its source, and should be reinforced through the use of posters and signs. Recurrent training is necessary to help maintain an awareness of FOD.
The U.S. Federal Aviation Administration (FAA) and International Civil Aviation Organization (ICAO) require a daily, daylight inspection of airplane maneuvering areas and removal of FOD. In addition to performing these inspections at the beginning of the day or shift, personnel on the airside should look for FOD during their normal shifts. Ongoing construction requires more frequent inspections. It may even be necessary to assign dedicated personnel to continually inspect for FOD during major construction activities. Flight crews should report to air traffic control and station operations any FOD they observe on runways and taxiways. Airlines and airplane handling agents should designate individuals to inspect gate areas prior to airplane movement to and from the gate.
Sweeping. Sweeping may be done manually or with the airfield sweeper, which is the most effective equipment for removing FOD from airsides. The sweeper removes debris from cracks and pavement joints, and should be used in all areas except for those that can be reached only with a hand broom. All airside areas, including aircraft maneuvering areas, aprons and gates and the areas adjacent to them, should be swept routinely. The areas in which ground support equipment (GSE) is staged should be swept periodically. Magnetic bars. 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 operating on the airside should be inspected periodically to ensure that they have no loose items that can fall off. Rumble strips. Driving over rumble strips dislodges FOD from vehicle undercarriages. The strips, which are 10 to 15 ft long, can be moved and used at transitions from the landside to the airside, or adjacent to airside construction areas. FOD containers. These containers should be placed at all gates for the collection of debris. The containers should be 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. 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. Other means for preventing FOD damage include wind barriers and netting to restrict the movement of airborne FOD, fencing to prevent animals from entering the airfield, and well-maintained paved surfaces. If damaged pavement cannot be repaired immediately, airplanes should take an alternate route.
Both airside and landside construction activities, as well as scheduled maintenance, should be communicated to airport users as early as possible. 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. Access to and from construction sites should avoid areas of aircraft operation. Contractors must fully understand the requirements and penalties incorporated in their contracts regarding the control and removal of FOD. FAA Advisory Circulars 150/5380-5B, Debris Hazards at Civil Airports, and 150/5370-2C, Operational Safety on Airports During Construction, provide excellent guidelines for coordinating day-to-day FOD prevention during construction. return to top | Boeing Home | Commercial |
