The U.S. Coast Guard seeks quotes for opening, inspecting, reporting on, and potentially overhauling three Fairbanks Morse Defense overspeed trip assemblies (NSN 2815 01 606 2501); no substitute parts are acceptable, and proprietary data/drawings will not be provided. Offerors must submit an all-or-nothing firm fixed price that includes an inspection fee, with award made to the lowest-priced, technically acceptable offeror registered in SAM. Delivery is required by 12/20/2026, F.O.B. destination, to the Coast Guard receiving facility in Baltimore, MD. Detailed packaging, marking, and shipping container requirements apply, and failure to comply may result in rejection and nonpayment. The work supports the Coast Guard Medium Endurance Product Line and includes payment of the inspection cost if items are beyond economic repair.
