FOD stands for Foreign Object Damage. What does it refer to?

• A. Loose objects on the flightline.
• B. Damaged fuel lines.
• C. Failed equipment tests.
• D. Unauthorized personnel on the flightline.

Answer: (A)

Foreign Object Damage means any object that is not part of the aircraft but can cause damage if it enters or contacts critical systems, especially the engine. On the flightline, loose objects—tools, fasteners, debris—pose the classic FOD risk because they can be sucked into an engine or strike surfaces during start, taxi, or takeoff. That makes the choice describing loose objects on the flightline the best match. Damaged fuel lines, failed equipment tests, and unauthorized personnel are safety concerns, but they are not what FOD refers to.
