What are maintenance-related FOD risks and how can they be prevented?

• A. Tools left on top of engine or in inlet duct; hardware, safety wire, protective caps; items in pockets; prevent by housekeeping and securing items.
• B. FOD only occurs during flight.
• C. FOD cannot occur during maintenance.
• D. FOD only concerns birds.

Answer: (A)

Maintenance-related FOD comes from items used during work that can become debris in the engine or on the airframe. Tools left unsecured, resting on top of an engine or in an inlet duct, loose hardware, safety wire, protective caps, and even small items left in pockets can fall into openings or be ingested, causing damage or failure when the system operates. The best way to prevent this is through good housekeeping and securing every item. Implement a tool control approach: account for tools, store them in designated cases, remove or secure loose hardware, cap or plug openings as needed, and ensure pockets are empty before closing access areas. After work, conduct a thorough check to confirm nothing is left behind and all protective coverings are correctly removed or left in place as required. Other statements aren’t accurate because FOD isn’t limited to flight; it can occur during maintenance as well. It’s not true that maintenance cannot produce FOD, and while birds are a FOD source, they are only one of many possibilities—maintenance activities themselves create significant risk when tools and parts aren’t properly managed.
