This sole-source repair/refurbishment requirement against an existing BOA covers submarine Fly-By-Wire Ship Control System flight critical components (FBW SFCC) and includes strict inspection, traceability, configuration control, quality, certification, and packaging requirements. Offerors must hold a valid U.S. CONFIDENTIAL or higher security clearance and handle classified material under NISPOM. After receipt of carcasses, the contractor has 45 days to complete teardown and evaluation and submit a Firm-Fixed-Price quote for full repair; the requested repair turnaround time is 365 days. Pricing may be estimated or firm-fixed, and offerors should also provide a beyond-repair/beyond-economical-repair price and approximate new-item cost if available, excluding shipping costs. Government quality assurance is performed at source, the order may be DO-rated under DPAS and use CAV, and non-OEM offerors must identify the OEM and provide signed distributor authorization.
