In a progressive inspection program, who must supervise the inspections?

• A. the owner
• B. a certificated mechanic who is not an IA
• C. the pilot in command
• D. an A&P with an IA

Answer: (D)

In a progressive inspection program, supervision must come from someone with Inspection Authorization. That person needs to oversee and approve the ongoing inspections, ensuring compliance with airworthiness standards. In practice, the supervisor is an A&P who also holds an IA, giving them both the technical capability to perform and inspect work and the authority to endorse the program's progress. An owner or pilot in command isn’t equipped to supervise, and a mechanic who is not an IA doesn’t have the required supervision authority. An A&P with an IA fits both the required supervision role and the maintenance authority needed for the progressive inspection program.
