28 -- VALVE, STEM GUIDE

This contract involves qualification requirements established by Engineering for a specific item, the Valve, Stem Guide (NSN 2810-01-532-4701, Part Number 4088012-01), used in F100 engine applications manufactured by Pratt & Whitney. The qualification requirements are mandated for all models and series of F100 engine items identified as Critical Safety Items by the Cognizant Engineering Authority, excluding Flight Safety Critical Parts. The authorization for these manufacturing qualification requirements is formalized through a document signed by the head or designee of the Cognizant Engineering Authority, and previous approvals remain valid unless superseded by more recent documentation. Interested parties must submit written requests to obtain the Qualification Requirements from The Small Business Office at Tinker AFB, with no telephone requests allowed. The solicitation is classified as a sources-sought notice under NAICS code 336412, and there is no set aside type specified. The purpose of this notice is to identify potential sources capable of meeting these specialized qualification standards rather than to solicit proposals directly, and there is no set issue or response date provided. The overall focus ensures that manufacturers comply with stringent engineering controls to guarantee the safety and reliability of critical components used in F100 engines.
