Cylinder Assembly (Load Arrestor) PN 1171-3

The Air Force Sustainment Center is conducting market research to locate manufacturers capable of qualifying and producing a flight‑critical Cylinder Assembly (Load Arrestor) (NSN 1680‑01‑181‑4175MH, P/N 1171‑3) for the B‑1 bomber ejection‑seat system. The item is a unique, proprietary component with no commercial equivalent, and the government currently identifies Collins Aerospace as the sole source, but seeks additional interest. • Qualification and production of a proprietary load‑arrestor cylinder assembly meeting exact OEM specifications and material requirements. • Item is flight‑critical, used in high‑rate deceleration events for B‑1 bomber ejection seats; no commercial or dual‑use equivalents exist. • Deadline for capability statements is November 13 2026; intent is to award a sole‑source contract to the incumbent, but other firms may submit interest.
