What is accomplished during an aircraft 100 Hour Maintenance Inspection

Because we are a Flight School, we’re required to comply with stricter, uncompromising directives prescribed by the Federal Aviation Regulations (FAR’s)

• Engine & Propeller: The oil is changed, filter is cut and inspected for contaminants, spark plugs are cleaned/gapped/tested, magnetos are checked, and compression is tested.

• Airframe & Structure: Panels, cowlings, and fairings are removed for inspection of the fuselage, wings, and tail for damage, corrosion, or stress.

• Systems & Components: Fuel systems, electrical wiring, flight controls (cables, pulleys), and avionics are inspected.

• Landing Gear: Wheels are removed, bearings repacked, tires checked for pressure/wear, and brakes inspected.

• Run-up: A final engine run-up checks for performance issues, proper magneto operation, and instrument function. 

The inspection also includes checking for compliance with all Airworthiness Directives (ADs) and required service bulletins.
