The 100 Hour Inspection Checklist is a comprehensive evaluation of the overall condition of an aircraft. It is typically conducted every 100 hours of operation and includes a thorough visual inspection of the exterior and interior of the aircraft, as well as all components, systems, and accessories. It also involves a complete inspection of the engine, fuel system, propeller, electrical system, and instrumentation. Additionally, all required maintenance items, such as lubrication, are also included in the 100 Hour Inspection Checklist. This inspection helps to ensure the safety of the aircraft and its passengers, as it allows any potential problems to be quickly identified and rectified before they become a hazard.
