For rental aircraft used for flight instruction, which inspections are required?

• A. Annual condition and 100-hour inspections
• B. Biennial inspection only
• C. Mandatory transponder test only
• D. Functional check every flight

Answer: (A)

The main idea is that aircraft used for rental and flight instruction must meet two maintenance schedules: an annual inspection and a 100-hour inspection. The annual inspection is a standard requirement for all aircraft and must be completed every 12 calendar months to verify overall airworthiness. In addition, aircraft used for hire or flight instruction must undergo a 100-hour inspection at intervals not to exceed 100 hours of time in service, ensuring that wear and systems are checked more frequently due to the higher usage. So, for rental aircraft used for instruction, both inspections are required.

The other options don’t fit because there isn’t a biennial-only requirement; a transponder test alone doesn’t satisfy the mandated maintenance, and a functional check every flight is not a substitute for the required periodic inspections.
