FOD can be generated from airport infrastructure (pavements, visual aids), 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).  FOD can be composed of any material of any color and size. In a one year airport study in France, over 60% of the items were metal followed by rubber (18%), black items made up nearly 50% of the FOD collected, and the size of FOD was 1 inch by 1 inch (2.5 cm x 2.5 cm) or smaller. Typical foreign objects include 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;

  • flight line items (nails, personnel badges, pens, pencils, 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; and paper products.
