Downloaded from https://www.everyspec.com ADS-39A (HDBK) component shall then be inspected to the extent necessary to substantiate all applicable drawing and specification balance requirements have been met. Parts requiring balancing verification are identified in Attachment 1. 3.3.3.6 Hardness 3.3.3.6.1 Components which are heat treated during the manufacturing process shall have hardness checks performed to insure the proper hardness has been obtained. Components requiring hardness checks are listed in Attachment 1.
3.3.4 Test 3.3.4.1 Material 3.3.4.1.1 One of the components produced by the candidate alternate source shall undergo a complete material evaluation by a Government-approved facility. This evaluation shall include destructive and/or non-destructive testing as required to verify applicable metallurgical, material, and/or process requirements of the drawing, material specification, and (when applicable) design specification have been met. The Government reserves the right to witness any or all of these inspections.
3.3.4.1.2 Any heat treat coupons used to control the heat treat process shall be sectioned and compared to the cut-up of the actual part, to insure the heat treat characteristics of the coupon adequately reflects those of the actual parts. If this has been done in-process, copies of all coupon tests and cut-up reports shall be provided. 3.3.4.1.3 Bearings shall have the inner and outer race and rolling elements sectioned to substantiate proper microstructure and hardness. 3.3.4.1.4 Gears shall be sectioned to substantiate proper case depth, core hardness, and microstructure. 3.3.4.1.5 Components requiring metallurgical or material testing and evaluation are identified in Attachment 1.
3.3.4.2 Endurance Testing 3.3.4.2.1 When applicable, one of the components produced by the candidate alternate source shall undergo an endurance test. Endurance testing shall be conducted at a Government- approved facility. 7
