Foreign Object Debris (FOD) can come in many different forms and may produce disastrous effects if not identified and corrected. In severe cases, FOD can directly threaten safety of flight crews and integrity of the aircraft.
FOD prevention is an essential element in all Company activities and is the responsibility of every Company employee.
The establishment of an effective and compliant FOD prevention and control program will:
– Provide employee training
– Identify potential problem areas and actions
– Provide the tools for employees to prevent FOD incidents
– Assist management in proper planning
– Coordination of corrective actions
– Establish a climate of “Continuous Awareness”
– Use the lessons learned by the industry to reduce costs and improve safety.
