Who should prepare FAA Form 337 when the work requires it?

• A. The person who performs or supervises the work
• B. The aircraft owner
• C. The FAA inspector
• D. The maintenance shop receptionist

Answer: (A)

Form 337 records a major repair or alteration to the aircraft and becomes part of the maintenance records. The person who performed or supervised the work is the one with firsthand knowledge of exactly what was done, the approved data that was followed, the parts used, and the inspections that took place. That person is responsible for preparing the form and ensuring its accuracy before it’s filed with the FAA. The aircraft owner isn’t automatically the preparer unless they did or supervised the work themselves; an FAA inspector reviews and approves the submission rather than preparing it; and a receptionist wouldn’t have the qualifications to certify the work.
