FAA Form 337 is primarily used to record and document which of the following?

• A. Routine maintenance
• B. Major repairs and alterations
• C. Airworthiness determinations
• D. Inspection records

Answer: (B)

Form 337 is used to record major repairs and alterations to an aircraft. It serves as the official documentation for significant work that could affect the airworthiness, such as structural changes, modifications in weight or balance, or alterations requiring engineering data and potentially FAA approval. Because of that, it’s the appropriate vehicle for detailing what was done, the data used, and who approved it, and it becomes part of the aircraft’s maintenance records. Routine maintenance and minor repairs are tracked in regular maintenance logs rather than on this form. Airworthiness determinations and routine inspection records are handled through other processes and records, not via Form 337.
