100 Hour Inspection Checklist

Annual Inspection VS 100 Hour Inspection

100 hour inspections and annual inspections are often mistaken for one another. Though their general scope may be similar, there are a number of differences that separate the two. Below are key differences that distinguish annual inspections from 100 hour inspections:

1. WHO performs the inspection
   Only certified A&P mechanics with an inspection authorization can perform an annual inspection. However, no special inspection authorizations are necessary to conduct a 100 hour inspection.
2. WHEN to perform
   100 hour inspections are performed after every 100 hours of flight time which means it may be performed more than once per year. Annual inspections, however, are required to be conducted every 12 calendar months regardless of total flight time.
3. WHAT the inspection covers
   Annual inspections and 100 hour inspections may have the same inspection scope and detail, but they differ in terms of regulatory requirements. Tasks such as inspecting components attached to the engine like propellers, magnetos and carburetor should be accomplished annually, while others like checking and adjusting fuel pressures and brakes are to be accomplished each 100 hours.
