FOREIGN OBJECT DAMAGE (FOD)
FOD is any foreign object that does not belong on the runway, taxiway, or ramp area. FOD can cause damage to aircraft, and in rare instances, cause an accident. Typical FOD items are aircraft parts, tire fragments, mechanics’ tools, nails, luggage parts, broken pavement and stones.
  • Damage usually occurs when the aircraft is taking off or landing. The intake suction from a jet engine is powerful enough to suck up loose material lying on the runway, and the winds created by a helicopter or prop-driven aircraft's rotors or by a jet blast can send such objects airborne, creating hazards to nearby personnel.
