FAA Aviation Mechanic General (AMG)Regulations, Records and Human FactorsHard
A mechanic completes a repair that involved replacing a flight control component that could appreciably change the airplane's flight characteristics. Under 14 CFR 91.407, what must occur before passengers may be carried?
- AThe aircraft must be re-weighed and a new weight and balance report issued
- BThe FAA must issue a special airworthiness certificate
- CThe owner must obtain written consent from the type certificate holder
- DA certificated pilot must operationally check the repaired system and log the flight in the aircraft records
Show answer & explanationAnswer & explanation
Correct answer: D. A certificated pilot must operationally check the repaired system and log the flight in the aircraft records
14 CFR 91.407(b) requires that when maintenance may have appreciably changed the aircraft's flight characteristics or substantially affected its flight operation, the aircraft must be test flown by a pilot holding at least a private pilot certificate, who operationally checks the repaired system and makes an appropriate log entry, before it may carry passengers.
Why the other options are wrong
- A. Reweighing is only required for weight/balance-affecting changes, not automatically for flight control repairs.
- B. A special airworthiness certificate has nothing to do with this repair scenario.
- C. No regulation requires type certificate holder consent for such repairs.
91.407(b) Operational Check Flight
Requires a test flight by a qualified pilot before carrying passengers after maintenance that could appreciably affect flight characteristics.
- Applies to repairs/alterations affecting flight characteristics or operation
- Pilot must hold at least a private pilot certificate
- An appropriate log entry documenting the check flight is required
Memory trick: 'Fly it first, fill it with passengers second.'
