What specific FOD prevention measures should be implemented during aircraft engine maintenance performed on the ramp?

During aircraft engine maintenance on the ramp, implementing rigorous FOD (Foreign Object Debris) prevention measures is critical to protect the engine from damage. First, designate a FOD-free zone around the engine being serviced. This involves clearly marking the area with cones or tape to restrict access and prevent accidental entry of foreign objects. All tools and equipment used during maintenance must be inventoried before and after the work to ensure nothing is left behind. A tool control program is essential, utilizing shadow boards or other systems to quickly identify missing items. Mechanics should thoroughly inspect their clothing and pockets to remove any loose items, such as pens, coins, or buttons, that could potentially fall into the engine. Tool tethers should be used to secure tools to prevent them from dropping. The engine intakes and exhaust should be covered with appropriate covers or plugs whenever work is not actively being performed on those areas. This prevents foreign objects from entering the engine's internal components. During the maintenance, use FOD screens or protective barriers around the work area to contain any small parts or debris that may be generated. Regular FOD walks should be conducted before, during, and after the maintenance to detect and remove any foreign objects. These walks involve systematically inspecting the area for any debris, no matter how small. Immediately clean up any spills of fluids, such as oil or hydraulic fluid, as these can attract and trap FOD. A designated FOD container should be readily available for disposing of any collected debris. A detailed record of all FOD prevention measures taken should be maintained. This documentation can be used to identify any weaknesses in the FOD prevention program and to improve procedures. Finally, ensure that all personnel involved in the maintenance are properly trained on FOD prevention procedures and understand the importance of adhering to them.
