28 -- Seal, Metallic, Airc

The contract outlines qualification requirements established by Engineering for a new manufacturing item, specifically the metallic seal designated for the F-100-229 engine, with National Stock Number 2840-01-308-4482NZ and part number 4075237. These qualification requirements apply to all models and series of F100 engine items identified and approved as Critical Safety Items by the Cognizant Engineering Authority, excluding Flight Safety Critical Parts. The manufacturing qualification requirement document (MQR-1) is authorized separately by the signature of the Cognizant Engineering Authority Head or their designee, and prior approvals under previous revisions remain valid unless superseded by a new authorization. The contract is intended as a sources-sought notice rather than a formal request for proposal, and interested parties can request qualification requirements or drawings via written communication to The Small Business Office at Tinker Air Force Base, with no telephone requests accepted. This contract is associated with NAICS code 336412, which relates to aircraft engine and engine parts manufacturing. The notice was posted on February 21, 2008, serving primarily as an informational solicitation to identify potential sources capable of meeting the qualification for this critical part. The document emphasizes the stringent controls on requests and documentation to ensure compliance with engineering standards and safety requirements for manufacturing this metal seal, critical to the operation and safety of F-100 engines.
