Can a certificated A&P mechanic supervise an unlicensed person as the unlicensed person performs a 100-inspection on an aircraft?

• A. Yes, under direct supervision by the mechanic.
• B. Yes, if the unlicensed person is in training.
• C. No, but they may supervise multiple inspections.
• D. No, a certificated mechanic must personally perform the inspection.

Answer: (D)

The main rule here is that inspections requiring a certificate must be performed by someone who holds the appropriate certificate. A 100-hour inspection is one of those inspections; it must be done by a certificated mechanic (A&P). Even though a certificated mechanic can supervise the work of an unlicensed person on tasks that don’t require a certificate, the actual performance of a 100-hour inspection cannot be delegated. The inspection must be performed by the certificated individual, and the record signed accordingly. That’s why the answer is that a certificated mechanic must personally perform the inspection.
