§ 101-37.601 - What responsibilities does the owning/operating agency have in the management and use of Government aircraft parts?

(a) The owning/operating agency is responsible for ensuring the continued airworthiness of an aircraft, including replacement parts. The owning/operating agency must ensure that replacement parts conform to an approved type design, have been maintained in accordance with applicable standards, and are in condition for safe operation.

(b) In evaluating the acceptability of a part, the owning/operating agency should review the appropriate log books and historical/maintenance records. The maintenance records must contain the data set forth in the latest version of Federal Aviation Administration (FAA) Advisory Circular 43-9. When the quality and origin of a part is questionable, the owning/operating agency should seek guidance from the local FAA Flight Standards District Office (FSDO) in establishing the part's airworthiness eligibility.
