Downloaded from https://www.everyspec.com ADS-39A (HDBK) 3.3.4.2.5.6 At the conclusion of the endurance test, the test assembly shall be disassembled in accordance with the SOW to allow a complete evaluation (dimensional, visual, NDI) of the test component and associated assembly components (mating gears, bearings, etc.). Components shall be subjected to nondestructive test procedures as required to insure no adverse wear or damage is present. The Government reserves the right to witness the teardown and evaluation, and to provide written action items (chits) to the candidate alternate source.
The candidate alternate source shall be responsible for addressing all concerns raised in the post-test evaluation of the test component and test assembly. 3.3.4.2.6 Approval shall be based on the wear characteristics of the test component or assembly at the conclusion of testing, as determined by the Government. In the event unacceptable wear or other damage is present, the candidate alternate source shall take appropriate actions to revise the manufacturing process in order to produce an acceptable component. The candidate alternate source may be required to repeat the endurance test in whole or in part with new or reworked test components to insure any action taken has the desired result.
3.3.4.3 Clutch Test 3.3.4.3.1 When applicable, one of the components produced by the candidate alternate source shall undergo a clutch performance test. Testing shall be conducted at a Government-approved facility. 3.3.4.3.2 Components and assemblies requiring clutch performance testing are to be incorporated into the higher-level assembly that is needed to support testing (hereinafter referred to as the “test assembly”). The level of assembly used (e.g., complete gearbox or clutch assembly, or a specific quill assembly or module) is usually dependent upon the test facility chosen.
For individual components requiring testing, the component shall be incorporated into the test assembly by an approved assembly source. For assemblies requiring testing, the assembly shall be accomplished by the candidate alternate source. Assembly instructions shall be as specified in the SOW. 3.3.4.3.3 Clutch components and assemblies requiring testing are identified in Attachment 1. 3.3.4.3.4 Clutch components undergoing testing shall be installed in mesh with components produced by approved and tested sources. 3.3.4.3.5 Testing shall be conducted by a Government-approved facility.
Specific Statements of Work (SOW) for the test shall be prepared by ATCOM Engineering after the inspection requirements of Section 3.3.3 above have been substantiated. Testing shall be accomplished in accordance with TEST-STD-1. General requirements are given below. 3.3.4.3.5.1 Each clutch test assembly shall be subjected to 200 engagements/disengagements. 9
