FAA Form 337 requires two copies: one is kept with the aircraft maintenance records and one is forwarded to the local FSDO within 48 hours after the work is approved for return to service.
Question 2: Under 14 CFR Part 43, who is authorized to approve an aircraft for return to service after a major repair?
- Any certificated mechanic holding an Airframe or Powerplant rating
- A certificated mechanic holding both Airframe and Powerplant ratings

Correct answer: A certificated mechanic with an Inspection Authorization (IA) or a certificated repair station
Under 14 CFR 43.7, only a certificated mechanic holding an Inspection Authorization, a certificated repair station, or the aircraft manufacturer may approve a major repair for return to service.
Question 3: According to 14 CFR Part 1, which of the following is an example of a major alteration to an airframe?
- Replacing a worn seat cushion with an FAA-approved replacement
- Installing a supplemental oxygen system not in the aircraft's approved type design (Correct answer)
- Replacing a cracked windshield with the same part number component
- Repainting the aircraft exterior with a different color scheme
Correct answer: Installing a supplemental oxygen system not in the aircraft's approved type design
A major alteration is one that might appreciably affect structural strength, flight characteristics, or other airworthiness qualities, such as adding equipment not in the type design.
Question 4: When must FAA Form 337 be submitted to the appropriate FAA FSDO after completing a major repair or alteration?
- Within 24 hours of completing the work
- Within 48 hours after the work is approved for return to service (Correct answer)
- Within 30 days of the work completion

Correct answer: Within 48 hours after the work is approved for return to service
14 CFR 43.9 and the instructions on Form 337 require the completed form to be forwarded to the local FSDO within 48 hours after the aircraft is returned to service.
Question 5: Which section of FAA Form 337 is used to describe the data used to substantiate the repair or alteration?
- Block 3 — Aircraft Information
- Block 7 — Conformity Statement
- Block 8 — Description of Repair or Alteration (Correct answer)
- Block 5 — Unit Identification
Correct answer: Block 8 — Description of Repair or Alteration
Block 8 of FAA Form 337 is where the technician describes the repair or alteration in detail, including the data source used to substantiate the work.
Question 6: A certificated mechanic finds that a repair on an aircraft falls under the 'major repair' category. Without an Inspection Authorization, what is the mechanic's authorized role in this repair?
- The mechanic may neither perform nor sign off on the repair
- The mechanic may perform the repair but not approve the aircraft for return to service (Correct answer)
- The mechanic may approve return to service if supervised by an IA holder
- The mechanic may perform and sign off the repair if it does not involve the primary structure
Correct answer: The mechanic may perform the repair but not approve the aircraft for return to service
A certificated A&P mechanic without an IA may perform major repair work but cannot approve the aircraft for return to service — that approval requires an IA, repair station, or manufacturer.
