Which statement is true about signing FAA Form 337 by a certificated mechanic without an inspection authorization?

• A. It certifies that the work was done in accordance with 14 CFR part 43
• B. It certifies that the work is airworthy
• C. It certifies that the installation was performed by IA
• D. It certifies that the aircraft has an airworthiness directive

Answer: (A)

FAA Form 337 documents major repairs or alterations and the signer’s statement that the work was performed in accordance with 14 CFR Part 43, which governs maintenance, repairs, and alterations and the inspections that accompany them. Signing without an inspection authorization simply indicates compliance with those Part 43 standards for the work done; it does not itself certify airworthiness. Airworthiness is determined through proper inspection and approval, typically involving the appropriate inspector or IA if required. The form also does not imply that an IA performed the installation, nor does it certify that an airworthiness directive applies.
