§145.1 Applicability.
(a) This part prescribes the requirements for issuing repair station certificates and associated ratings to facilities for the maintenance and alteration of airframes, powerplants, propellers, or appliances, and prescribes the general operating rules for the holders of those certificates and ratings.
(b) A certificated repair station located in the United States is called a "domestic repair station". A repair station located outside of the United States is called a "foreign repair station".
(c) A manufacturer of aircraft, aircraft engines, propellers, appliances, or parts thereof, may be issued a Repair Station Certificate with a limited rating under subpart D of this part.
