FAA Aviation Mechanic General (AMG)Regulations, Records and Human FactorsMedium
An A&P mechanic without an Inspection Authorization (IA) has just completed a major repair on a type-certificated airplane using FAA-approved data. According to 14 CFR part 43, who may approve this repair for return to service?
- AAny commercial pilot who operates the airplane
- BA student mechanic working under the supervision of the repairing mechanic
- CA certificated mechanic holding an Inspection Authorization (IA)
- DThe mechanic who performed the repair, using their A&P certificate privileges
Show answer & explanationAnswer & explanation
Correct answer: C. A certificated mechanic holding an Inspection Authorization (IA)
Per 14 CFR 43.7, major repairs and alterations may only be approved for return to service by an appropriately rated certificated repair station, the manufacturer, or a mechanic holding an Inspection Authorization. An A&P without IA may perform the work but not approve it for return to service.
Why the other options are wrong
- A. A pilot certificate carries no maintenance approval authority.
- B. Student mechanics have no independent authority to approve work.
- D. An A&P mechanic without IA may perform but not approve a major repair for return to service.
Return to Service Authority (43.7)
Defines who may legally approve aircraft, engines, and appliances for return to service after maintenance.
- Major repairs/alterations require IA, repair station, or manufacturer approval
- A&P mechanics may approve minor repairs and preventive maintenance
- IA is an added rating beyond basic A&P certification
Memory trick: 'Major needs the Major League' — only IA/repair station/manufacturer can sign off major work.
