Eligibility and Evaluation of U.S. Military Surplus Flight Safety Aircraft Parts, Engines, and Propellers
This advisory circular (AC) provides information and guidance for use in evaluating and determining the eligibility of U.S. military surplus flight safety critical aircraft parts (FSCAP), engines, and propellers for installation on Federal Aviation Administration (FAA) type-certificated products. This AC is applicable to all U.S. military surplus FSCAP, engines, and propellers, irrespective of when and by what process these products or parts became available. In the absence of FSCAP classification of military surplus parts by the Department of Defense (DoD), such parts should be identified and classified as FSCAP using the guidance contained in this AC. For information and guidance on determining the eligibility of parts other than FSCAP, refer to AC 20-62, Eligibility, Quality, and Identification of Aeronautical Replacement Parts. Like all AC material, this AC is not mandatory and does not constitute a regulation. It is issued for guidance purposes and to outline one method of compliance with the rules. In lieu of following the method(s) prescribed herein without deviation, a person may elect to follow an alternative method, provided the FAA finds the alternative method to be an acceptable means of complying with the applicable requirements of Title 14 of the Code of Federal Regulations (14 CFR).
|20-97B||AFS-306||Aircraft Tire Maintenance and Operational Practices This advisory circular (AC) provides recommended tire care and maintenance practices needed to assure the safety of support personnel and the continued airworthiness of aircraft.

Guide for Developing a Receiving Inspection System for Aircraft Parts and Material - Change 1
This advisory circular (AC) provides guidance and information for incorporation into operators’ existing receiving/inspection systems to help prevent the introduction of unairworthy parts into inventories. The aim is to establish sufficient traceability to establish that the part(s) were manufactured under Title 14 of the Code of Federal Regulations (14 CFR) part 21, were previously determined to be Airworthy under 14 CFR part 43, and produced to established industry or U.S. Government standards or accepted foreign standards. Like all AC material, this AC is not mandatory and does not constitute a regulation. It is issued for guidance and to outline a method of compliance with the rules. This is one means but not the only means for developing a receiving inspection system. In lieu of following the method(s) prescribed herein, the applicant may elect to follow an alternate method.
