Foreign Object Damage/Debris
FOD costs the aviation industry $13 billion per year in direct and indirect costs. Direct costs include engine maintenance, tire replacements, and aircraft body damage from ingesting foreign objects. Indirect costs, which are much higher, include delays, cancellations, schedule disruptions, liability, and loss of customers. Repairing FOD damage to aircraft engines can exceed 20% of the original purchase price of the engine. Implementing an effective FOD control program through organizational commitment, training, accountability, and coordination can help reduce these costs and prevent injuries from FOD.

- 16. FOD AND MAINTENANCECOSTS The effect of Foreign Object Debris (FOD) on maintenance costs can be significant. For example, the cost to repair a FOD-damaged engine can easily exceed $1 million. FOD can also incur extensive indirect costs, including: •Flight delays and cancellations, leading to a loss of customers. •Schedule disruptions caused by the need to reposition airplanes and crews. •Potential liability because of injury. •Additional work for airline management and staff. The cost of repairing FOD damage to an engine can easily exceed 20 percent of its original purchase price. Purchase cost of MD-11 engine $8-10 million Purchase cost of MD-80 engine $3-4 million MD-11 engine overhaul to correct FOD damage $500,000-1.6 million MD-80 engine overhaul to correct FOD damage $250,000-1.0 million MD-11 fan blades (per set*) $25,000 MD-80 fan blades (per set*) $7,000 *Fan blades are balanced and replaced as a set.

- 19. PACIFIC OCEAN (June19, 2008) Sailors search the flight deck for foreign object debris (FOD) during a FOD walkdown aboard the Nimitz- class aircraft carrier USS John C. Stennis (CVN 74). FOD walkdowns are conducted to reduce the potential for aircraft engines to become damaged and flight deck personnel to be injured by loose objects on the flight deck. Stennis and multiple embarked fleet replacement squadrons are conducting Fleet Replacement Squadron Carrier Qualifications (FRSCQ) off the coast of Southern California. FRSCQ's are conducted to qualify naval aviators in day and night carrier operations in the aircraft they will fly during their aviation career.
- 20. INDIAN OCEAN (May4, 2009) Sailors and Marines perform a foreign object debris (FOD) walk down after an all-hands call aboard the amphibious assault ship USS Boxer (LHD 4). FOD walk downs help prevent damage to aircraft from debris on the flight deck which could be ingested into a jet engine. Boxer is deployed as part of the Boxer Amphibious Readiness Group/13th Marine Expeditionary Unit supporting maritime security operations in the U.S. 5th fleet area of responsibility.

An effective debris-control program can greatly reduce the high cost of FOD damage and the potential for injury to personnel or passenger. FOD control is most effective when all affected parties coordinate their efforts.
