All components listed in the attachments and used for testing in accordance with this document must require substantiation of all drawing dimensional requirements. The results of this dimensional substantiation should be included in the inspection report and submitted to USAATCOM engineering for approval (see paragraph 1.3 .S). 1.3.4 Material Substantiation Components must only be fabricated from the material(s) specified.
Castings and forging must only be procured from sources which have been previously approved by the prime contractor or USAATCOM engineering for each specific part or component. Other material used will be in accordance with all applicable procurement specifications. Substantiation of compliance with these requirements is required for all components listed in the ETT in the FSPIS. To access the FSPIS, see the FSPIS User’s Guide or contact AMSAT-R-EBS. This substantiation should be included in the inspection report and submitted to the procuring service for approval (see paragraph 1.3.8).
1.3.5 Process Substantiation The service life of engine components, particularly high speed rotating parts, is greatly affected by the processes performed during the manufacture of these parts. It is imperative that all processes are performed in a manner virtually identical to that established during the development of these components. All processes used in the fabrication of engine components must be performed by sources which have been previously approved by the prime contractor or USAATCOM engineering for each specific part or component. Other processors may be approved by the prime contractor or USAATCOM engineering upon request or, if the need arises.
This includes heat treat, shot peen, finishes, forming, welding, coatings, plating, and all other processes used to manufacture the part. The component must also be subjected to all inspections (e.g., Nondestructive Inspection (NDI)) required by the drawing. Verification of compliance with process requirements and documentation of all inspection results is required for all components listed in the ETT in the FSPIS. Engine low cycle fatigue (LCF) spin pit testing may be required to substantiate parts lives in some cases. These should be included in an inspection report and submitted to USAATCOM engineering for approval (see paragraph 1.3.8).
No new sources for processing engine parts will be approved until they have met all of the above requirements. 1.3.6 Manufacturing Process Control
