Cylinder Assembly (Load Arrestor) PN 1171-3

The Department of Defense, through the Air Force Sustainment Center PZAAC Contracting Office, is conducting market research via a sources sought synopsis to identify capable sources for the qualification and production of the Cylinder Assembly (Load Arrestor), NSN 1680-01-181-4175MH, P/N 1171-3. This component is a military-unique, flight Critical Safety Item integrated into the B-1 bomber egress system. It serves a dual purpose as a rigid structural brace to absorb forward loads and prevent deflection of the upper ejection seat carriage, and as a hydraulic/pneumatic shock absorber to facilitate controlled seat retraction prior to ejection. Due to the critical nature of this part, strict adherence to the original equipment manufacturer technical data package, material metallurgy, and dimensional tolerances is mandatory, as any deviation could lead to catastrophic structural deformation, system failure, or loss of life. There are no known commercial equivalents for this component. Interested parties must submit capability statements by November 13, 2026, to Komkit Seshompo, with copies to PCO Carlos Renfroe and Buyer Kinser George. This action is for market research purposes only and does not constitute a formal request for proposal.
