Which statement about inspections is true?

• A. A 100-hour inspection can be performed by an A&P, while an annual inspection requires IA
• B. An annual inspection can be performed by an A&P
• C. A 100-hour inspection requires IA
• D. Both inspections require IA

Answer: (A)

The key idea is who is authorized to sign off these different inspections. A 100-hour inspection can be performed by an A&P mechanic, even without an Inspection Authorization. In contrast, an annual inspection requires the additional credential of an Inspection Authorization, held by the A&P performing the work. That combination—A&P doing the 100-hour, but requiring IA for the annual—is what makes this statement true. The annual is more comprehensive and thus needs the IA designation, while the 100-hour is a routine maintenance check that a regular A&P can handle.
