Downloaded from https://www.everyspec.com ADS-39A (HDBK) 3.3.5.2 When a component fails one of the required tests, the item shall be rejected. All failures, whether by noncompliance of hardware (dimensional or metallurgical) or failure during testing, and proposed modifications to either parts or testing procedures shall be documented and submitted to the Government before testing can resume. 3.3.5.3 Upon approval of all test and evaluation results, all manufacturing plans shall become "frozen,” and shall not be changed without first obtaining Government approval. Subsequent components shall be manufactured in accordance with these plans.
All substantiation evaluation and test documentation shall be provided to the Government. 3.3.5.4 Production components manufactured by the alternate source which do not meet the requirements of the approved drawings, manufacturing plans, and STDP shall not be used without written approval from ATCOM.
3.3.5.5 A 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, will require re-evaluation of the approval status. Alternate sources shall notify the Government immediately if they are under contract to supply an item in Attachment 1 and any of the above changes have occurred.
3.4 General 3.4.1 If an approved source listed in a Spares Technical Data Package is awarded a contract, and that source has not delivered parts to the Government within the last four (4) years, they must complete a metallurgical evaluation in accordance with paragraph 3.3.4.1, and a 200-hour endurance test in accordance with paragraph 3.3.4.2, to retain their approved status. If a source has not delivered parts to the Government within the last two (2) years, they must complete a metallurgical evaluation in accordance with paragraph 3.3.4.1, and a 25-hour endurance test in accordance with paragraph 3.3.4.2.
This effort shall be conducted as part of the First Article Test for the solicitation. 3.4.2 Alternate sources who are awarded contracts for components or assemblies for which they are already an approved source must certify that the part delivered under the additional contract will be produced using the same “frozen” planning used to produce parts under the original contract. Any contract given to an alternate source assumes the alternate source will use approved planning to produce the part.
If the source was not required to meet the requirements of this ADS when they became approved to manufacture a part, they shall be required to meet all requirements of this ADS to retain their approval status before being awarded another contract for the part. 11
