Which regulatory directive requires strict adherence to FOD prevention measures?

• A. DAFI 21-101, Aircraft and Equipment Maintenance Management
• B. DoDI 5100.01, DoD Operations
• C. FAA AC 43-1, Airframe Repair
• D. MIL-STD-129, Military Marking

Answer: (A)

FOD prevention is a crucial safety and maintenance discipline: debris and foreign objects can cause catastrophic damage to engines, fuel systems, and flight surfaces, so control must be built into daily maintenance tasks. The directive that most directly requires strict adherence to FOD prevention measures is the Air Force maintenance management instruction. It sets up the maintenance program structure and explicitly includes FOD prevention, tool control, housekeeping, and FOD walkdowns as standard procedures. This ensures every maintenance activity—whether inspecting, repairing, or assembling components—follows clear rules to keep work areas clean, manage fasteners and tools, and verify the absence of debris before flight or operation. The other directives lay out broader safety, civilian guidance, or unrelated topics like markings, and do not specify the aviation-focused FOD program requirements in the same way.
