The USCG is requesting quotations for a firm-fixed-price, sole-source overhaul of the Main Fuel Control, with work to be performed by the OEM (Woodward, Inc.) or an authorized overhaul facility. The initial order covers four overhauls, with an option for one additional overhaul at the same price and lead time, exercisable up to 365 days after award. Overhauls must comply with FAA guidelines, and offerors must provide certificates of conformance and traceability to the manufacturer. No drawings, specifications, or schematics are available from the agency. The requirement is unrestricted, and all responsible sources may submit offers.
