FAA Aviation Mechanic General (AMG)Regulations, Records and Human FactorsHard
A certificated repair station performs a major alteration on an aircraft under its air agency certificate and approved procedures. Regarding FAA Form 337, which statement is correct?
- AForm 337 is not required for any major alteration performed under a repair station certificate
- BOnly the aircraft owner may complete Form 337 in this situation
- CThe repair station may record the work in its own approved maintenance records in lieu of executing Form 337
- DThe repair station must submit Form 337 to the FAA within 48 hours
Show answer & explanationAnswer & explanation
Correct answer: C. The repair station may record the work in its own approved maintenance records in lieu of executing Form 337
14 CFR part 43, Appendix B allows a certificated repair station to document a major repair or alteration in its own approved maintenance records/work order system instead of completing a separate FAA Form 337, provided equivalent information is recorded.
Why the other options are wrong
- A. Form 337 (or the equivalent repair station record) is still required to document the major work.
- B. The mechanic or agency performing the work completes Form 337, not solely the owner.
- D. There is no 48-hour submission requirement for Form 337.
FAA Form 337 & Repair Station Exception
Form 337 documents major repairs/alterations, but certificated repair stations may use their own approved records instead.
- Form 337 required for major repairs/alterations by mechanics/IA
- Part 43 Appendix B allows repair stations to use their own equivalent records
- One copy of Form 337 normally goes to FAA, one stays with aircraft records
Memory trick: 'Repair stations write their own story instead of filling out Form 337.'
