This is a restricted solicitation for commercial items, anticipated to result in a firm-fixed-price purchase order awarded on a sole-source basis to Airbus Helicopters, Inc. All parts must have clear traceability to the OEM Airbus Helicopters, and only new, airworthy commercial or standard military parts will be accepted—no substitutes or alternate parts will be considered. Offerors must be able to provide a Certificate of Conformance and FAA-approved parts, with no drawings, specifications, or schematics available from the agency. The applicable NAICS code is 336413, with a small business size standard of 1,250 employees. All responsible sources with the required expertise may submit quotations, though the government believes Airbus Helicopters is the only known source for genuine OEM parts with the required traceability.
