This is a combined synopsis/solicitation for commercial items, anticipating a sole-source, firm-fixed price award to Airbus Helicopters, Inc. for OEM helicopter parts with full traceability. The requirement is restricted, and all parts must be new, FAA-approved, and procured with a Certificate of Conformance; no substitute or alternate parts will be considered. While the solicitation invites quotations from all responsible sources, it states the government's belief that Airbus Helicopters is the only known source capable of meeting the requirement. The closing date and time for receipt of offers is 17 April 2026 at 12:00 pm EST. Quotes and questions must be submitted by email to the specified address.
