ANO 145-APPROVED MAINTENANCE ORGANISATIONSChapter 2: Acceptable Means of Compliance8. Where a TC-holder or an approved production organisation is prepared to makeavailable complete data which is not referred to in aircraft manuals or service bulletinsbut provides manufacturing drawings for items specified in parts lists, the fabrication ofthese items is not considered to be within the scope of an approval unless agreedotherwise by PCAA in accordance with a procedure specified in the exposition.9. Inspection and Identification.Any locally fabricated part should be subjected to an inspection stage before,separately, and preferably independently from, any inspection of its installation. Theinspection should establish full compliance with the relevant manufacturing data, andthe part should be unambiguously identified as fit for use by stating conformity to theapproved data. Adequate records should be maintained of all such fabricationprocesses including, heat treatment and the final inspections. All parts, except thosehaving not enough space, should carry a part number which clearly relates it to themanufacturing/inspection data. Additional to the part- number the organisation's identityshould be marked on the part for traceability purposes.AMC 145.A.42 (d) Acceptance of Components1. The following types of components should typically be classified as unsalvageable:a. Components with non-repairable defects, whether visible or not to the naked eye;b. Components that do not meet design specifications, and cannot be brought intoconformity with such specifications;c. Components subjected to unacceptable modification or rework that is irreversible;d. Certified life-limited parts that have reached or exceeded their certified life limits, orhave missing or incomplete records;e. Components that cannot be returned to airworthy condition due to exposure toextreme forces, heat or adverse environment;f. Components for which conformity with an applicable airworthiness directive cannotbe accomplished;g. Components for which maintenance records and/or traceability to the manufacturercannot be retrieved.2. It is common practice for possessors of aircraft components to dispose ofunsalvageable components by selling, discarding, or transferring such items. In someinstances, these items have reappeared for sale and in the active parts inventories ofthe aviation community. Misrepresentation of the status of components and the practiceof making such items appear serviceable has resulted in the use of unsalvageablenonconforming components. Therefore Organisations disposing of unsalvageableaircraft components should consider the possibility of such components later beingmisrepresented and sold as serviceable components. Caution should be exercised toensure that unsalvageable components are disposed of in a manner that does not allowthem to be returned to service.15/01/2013 2-17 ANO-145-AWRG-1.1
