How should FOD be prevented?

• A. Replace all engines annually
• B. Follow your FOD program or be wary
• C. Use only metal fasteners
• D. Schedule inspections every year regardless of risk

Answer: (B)

Preventing foreign object damage relies on having and following a formal FOD prevention program that keeps tools, debris, and other objects out of the engine intake or paths and ensures every step is checked before operation. The best choice is to follow your FOD program because such a program provides the structured procedures, responsibilities, training, and controls needed to prevent objects from being left behind or misplaced. It covers tool control, housekeeping, prestart checks, covers and protective plugging, proper storage, and clear reporting so issues are caught and addressed consistently rather than relying on chance or ad hoc actions.

Replacing engines every year doesn’t address root causes and is impractical and costly; it’s not a substitute for daily diligence and proper controls. Using only metal fasteners might reduce some risk in specific scenarios, but FOD prevention is broader than material choices and requires a complete program to manage all potential debris and objects. Scheduling inspections once a year regardless of risk ignores the varying exposure and operational conditions that affect FOD risk, whereas a program-driven approach emphasizes ongoing, risk-based vigilance and continuous improvement.
