NAMSOPs will standardize these programs throughout aviation maintenance. As a plane captain, you will be involved with these programs. Therefore, you must know the purpose and scope of the special programs discussed in the following text. FOREIGN OBJECT DAMAGE (FOD) PREVENTION PROGRAM FOD is damage to aeronautical equipment caused by objects and debris foreign to that equipment. Foreign objects are also major safety hazards to personnel if the objects are left on the flight line/flight deck to be blown around by aircraft. The ingestion of foreign objects and debris into gas turbine engines is a problem that accounts for the largest percentage of premature engine removal. The removal of these engines consumes maintenance man-hours, imposes unscheduled workloads on supporting activities, and creates an unwarranted shortage of engines and spare engine parts in the supply system. Thus, the training capability and fleet operational readiness are drastically reduced. The majority of gas turbine engines undergoing depot rework exhibit some degree of FOD. Most FOD is caused by poor housekeeping, facility deterioration, improper maintenance practices, and carelessness. FOD cannot be tolerated; thus, the requirement to reduce FOD is mandatory. A successful FOD prevention program depends upon command support, personnel knowledge and awareness, and its integration into the total maintenance effort. As a plane captain, you can help prevent FOD by checking the deck for loose gear (nuts, bolts, washers, and safety wire) after maintenance is completed. Also, you should check the intakes and exhausts of your aircraft during the daily/turnaround inspection. TOOL CONTROL PROGRAM (TCP) The Tool Control Program (TCP) reduces the potential for tool FOD-related mishaps and keeps down the cost of tool replacement. This program gives you a fast way to account for all tools, both before and 5-24
