Which inspection requires an Inspection Authorization to perform?

• A. 100-hour inspection
• B. Progressive inspection
• C. Annual inspection (requires IA)
• D. Preflight inspection

Answer: (C)

An Inspection Authorization is the credential that allows someone to perform and sign off the annual inspection. The annual is the FAA-mandated, thorough airworthiness review of the airframe, engine, systems, and their records, and it requires an IA to conduct the inspection and officially approve the aircraft for return to service. Other inspections don’t require an IA: a 100-hour inspection can be done by a certificated mechanic (A&P), a preflight inspection is conducted by the pilot in command, and progressive inspections are an alternative program for certain operators but don’t hinge on IA sign-off for the inspection itself.
