Line maintenance stations in the US can perform major repairs and alterations the FAA has confirmed.
The clarification comes after ARSA called for more guidance, arguing that the agency’s failure to differentiate between the separate aspects of part 145 − which relate to ratings and authorisations − implied that non-specified activities were prohibited.
The FAA’s aircraft maintenance division has now confirmed that the regulations allow an “appropriately certificated and rated repair station to perform continuous line maintenance” at locations listed in its operations specifications.
The confirmation came as the US Transportation Security Administration adjusted its guidance on security of aircraft at on-airport repair stations in line with advice from ARSA.
It confirms that a repair station only has responsibility for the security of a large aircraft when it has “authority over the aircraft, contractual dominion or control of the aircraft, or when the repair station knows or should know that a large aircraft has been tendered to them by an aircraft owner or operator”.
