A & P Mechanic Maintenance Certification
by Mr. Bril
In Europe a U.S. registered helicopter (AS350-B2) has been maintained by a U.S. foreign repair station (FAR 145) maintenance organisation using the maufacturer’s maintanace program, but the maintenance has been cerified by an FAA Airframe & Powerplant (A&P) mechanic. Is this correct?
If the repair station has a rating and operations specifications authorizing them to maintain an AS350, they should sign off the work using a person authorized to approve aircraft for return aircraft to service on behalf of the the repair station. They should also use the repair station number on the release document.
However, an FAA A&P mechanic can maintain and release to service an U.S. registered AS350 helicopter if he has been trained and has the necessary tools to do so.
If the repair station does not have a rating for the AS350, and they contract to the A&P to perform or supervise the work, there is nothing to preclude him from approving the helicopter for return to service. Were can I find the correct explanations, which FAR's?ANSWER: FAR 43.7 – Persons authorized to approve aircraft for return to service.
