Public Law 100-456, section <a>805</a>b, requires that alternate sources comply with the same qualification requirements as those of the original source. "In procuring any spare or repair part that is critical to the operation of an aircraft or ship, the Secretary of Defense should require the contractor supplying such part to provide a part that meets all appropriate qualification and contractural quality requirements as may be specified and made available to propective offerors. In establishing the appropriate qualification requirements, the Secretary of Defense should utilize those requirements if available, which were used to qualify the original production part, unless the Secretary of Defense determines in writing that any or all such requirements are unnecessary." Potential alternate manufacturing sources of aircraft engine parts, components, or assemblies are required to provide substantiation that the specific item offered meets or exceeds the identical item furnished by the original manufacturer in terms of service life, strength, durability, form, fit, and function. The substantiation requirements for alternate manufacturing source approval are included in this document. Candidates for alternate source approval are required to submit to Army Aviation and Troop Command (USAATCOM), Engineering Directorate a plan designed to meet the substantiation requirements.
