  1. Foreign Object Damage (FOD)

  2. What is Foreign Object Damage • Aircraft damage or malfunction caused by a foreign object • May or may not be ingested, can include fuel contamination

  3. FOD program requirements • FOD prevention is an essential part of the unit’s accident prevention program • All unit personnel will participate • The unit FOD program will be in writing (para 3-2) • FOD SOP. A foreign object damage SOP is required. A sample FOD SOP in App D • A FOD checklist should be developed

  4. FOD program responsibilities • Commanders will: • Appoint on orders an FOD prevention officer (the ASO will not be the FOD Officer) • Appoint on orders an FOD prevention NCO • Integrate FOD into the commander’s accident prevention program • Ensure FOD is discussed at unit safety meetings

  5. ASO monitors, not manages the FOD program (para 1-6) • Publicizes the FOD prevention effort with posters, videos (PIN 29309, TF 46-4365) etc

  6. FOD officer: • Manages the unit FOD program • Delegates areas of responsibilities • Conducts FOD surveys • Is a member of the unit safety council

  7. FOD NCO: • Assists the FOD officer • Is a member of the unit enlisted safety council • Checks FOD containers a minimum of weekly

  8. Unit personnel: • Actively participate in FOD prevention • Perform all maintenance “by the book” • Cover open lines, ports etc • Account for all tools at the end of each maintenance operation • All tools should be marked

  9. FOD accident reporting is standard unless: (AR 385-40) • Damage is incurred solely from flying debris during operations in confined areas and unimproved landing sites • This is considered fair wear and tear (FWT) and for accident reporting purposes no cost is associated with the damage

  10. FOD accident reporting is standard unless: (AR 385-40) • Aircraft damage (other than engine) is discovered during scheduled maintenance is not included in accident cost

  11. FOD accident reporting is standard unless: (AR 385-40) • Class F. Reportable incidents confined to aircraft turbine engine damage (not APUs) as a result of internal or external FOD where that is the only damage. These incidents will be reported using D Form 2397-AB-R

  12. FOD prevention procedures: (TM 1-1500-204-23-1) • Regularly police parking areas, runways, taxiways, and run up and exhaust areas. Special attention shall be given to cleaning of cracks and expansion seams on flight ramps (para 3-2) • Periodically instruct personnel concerned with aircraft maintenance on foreign object hazards

  13. Ensure that air inlet and exhaust covers are installed at all times when engines are not being operated, except when it is known the engine will again be operated immediately following shutdown. • Provide properly marked receptacles (FOD cans) in all work areas into which trash, ferrous and non ferrous scrap, safety wire, etc. may be placed.

  14. Common problems: • Correcting operating errors instead of systemic defects • By not documenting on the spot corrections (operating errors) the ASO can’t see trends and find systems defects • Inadequate supervision • Get everyone, especially the commander involved

  15. Inadequate equipment • No FOD cans available • FOD cans on flightline contributing to FOD problem • Overflowing • No self closing lid • In the way, not marked

  16. Tool problems • Tool inventory not conducted at the end of each maintenance period • Broken tools • Unauthorized tools • Necessary tools not available

  17. Flightline FOD prevention • Trash dumpsters should not be kept on the flightline • Dunnage, plywood sheets, and loose items should not be stored on the flightline • Develop methods to secure inlet covers, tie downs, etc. from blowing loose in high wind

  18. FOD prevention in the FARP • Water Detection (Aqua -Glo) test performed daily • Fuel nozzle. Cap installed and hung on grounding rod • Rotorwash induced FOD

  19. FOD prevention in the FARP • Conduct FOD sweep of FARP • FOD cans with lids (cans and lids must be secured) • Account for tools and components (foil tape, pins, clips, etc.)

  20. Other FOD prevention techniques • Police as you go • FOD walks • Put FOD found in work area on a bulletin board, small pieces can be put in a plastic bag

  21. Other FOD prevention techniques • Display actual FOD at safety meetings • Ensure FOD is an area of interest during all safety surveys • Caution personnel who work on aircraft to not wear boots with “mud & snow” soles
