571.08 (1) No person shall install a used part on an aeronautical product, other than aircraft that are operated under a special certificate of airworthiness in the owner-maintenance or amateur-built classification, unless the part meets the standards of airworthiness that are applicable to the installation of used parts and are set out in Chapter 571 of the Airworthiness Manual and

• (a) is an airworthy part that has been removed from an aircraft for immediate installation on another aircraft;

• (b) is an airworthy part that has undergone maintenance for which a maintenance release has been signed pursuant to paragraph 571.11(2)(c); or

• (c) has been inspected and tested to ensure that the part conforms to its type design and is in a safe condition, and a maintenance release has been signed to that effect.

(2) If, under the terms of a loan agreement or an air operator parts pooling agreement, a used part has been obtained from a source not subject to these Regulations, no person shall permit the part to remain in service for longer than 90 days unless specifically authorized by the Minister on receipt of documentation demonstrating that the part conforms to the applicable type design.
