The Navy intends to award a sole-source contract to Sikorsky Aircraft Corporation as the original equipment manufacturer for four pylon fairings used on the MH-60R helicopter, citing the lack of available drawings or data rights for other suppliers. The government states that no other supplies or services will satisfy the requirement and expects to negotiate only with this approved source. Interested firms that are not already approved must submit a Source Approval Request, but the procurement will not be delayed while approval is pending. All responsible sources may submit a capability statement for consideration, and the government will consider any proposals received within the response period. Commercial item procedures will not be used; instead, FAR Part 15 acquisition rules, Buy American clauses, and UID requirements will apply.
