FAA Repair Station Functions
What functions may be performed by an FAA certified repair station?
An FAA repair station can perform the functions (tasks) necessary to inspect, repair, replace, or overhaul those aviation articles that they have been given an authorization (rating) for. The FAA lists and approves ratings on a form called operations specifications.
FAR 145 is the rule that governs repair station activities. FAR 145.59 lists the ratings that can be issued to a repair station. The repair station would have to apply for and prove that they have the necessary housing, facilities, equipment, materials, and data to perform the functions (tasks) required for each rating.
Following are the ratings that can be applied for:Airframe ratings
