Downloaded from https://www.everyspec.com ADS-43A-HDBK When an engine part, assembly, or component listed in the ETT fails any of the qualification requirements, the item must be rejected. All failures, whether by noncompliance of hardware (dimensional or metallurgical) or failure during testing, and proposed modifications to both parts and testing procedure must be documented and submitted to USAATCOM engineering before testing can be resumed.
Rejected engine parts, assemblies, or components must be replaced or reworked as specified by USAATCOM engineering to correct the deficiency, after which part or all applicable test(s) will be repeated, depending on the nature and severity of the failure. 1.5.3 Alternate Source Approval An alternate source is approved only for the manufacture of the component specified. A prospective vendor must be referred to the CASL for qualification by similarity guidance.
1.5.4 Changes in Approved Sources/Processes Any change in manufacturing location, such as to another plant of an individual vendor; a change in material processes or subvendors who perform a process; a change in material, casting, or forging suppliers; a change in manufacturing planning from the approved planning process; or a change in machining procedures which may affect component strength or durability may require retesting based upon a proposal from the alternate source and approval from USAATCOM engineering. Refer to CASL procedures for additional information. 9
