Naval Air Systems Command, on behalf of the Tactical Airlift Program Office (PMA-207), is conducting market research to identify qualified sources capable of supplying new or overhauled PT6A-60A turboprop engines that meet OEM specifications and applicable airworthiness, configuration-control, inspection, test, preservation, and technical-data requirements. The Government seeks responses from the OEM, OEM-authorized distributors, OEM-authorized MRO providers, and other responsible sources with relevant military aviation experience. Interested sources are asked to provide capabilities information covering company details, technical capability, schedule and capacity, commerciality and pricing, and small-business participation. This sources-sought notice is for market research and acquisition planning only, including obtaining estimated procurement costs, and is not a solicitation or commitment to procure.
