What is the biggest difference between a 100-hour and an annual inspection?
What is the biggest difference between a 100-hour and an annual inspection? When Are These Inspections Conducted. As the name suggests, 100-hour inspections are performed after every 100 hours of flight. That means it's performed more than twice a year. On the other hand, annual inspections must be conducted every 12 months (hence, the name) regardless of total flight time.
Do you need a 100 hr inspection for a checkride?
A 100-hour inspection would be required if the aircraft is used to carry passengers for hire, or if that aircraft is used for flight training and the instructor or the flight school provides that aircraft. Student-owned or club-operated aircraft generally do not require the 100-hour inspections.
