This is a Sources Sought Notice for market research, not a solicitation, to identify potential suppliers of factory-new Honeywell spare parts for HC-130J aircraft. The government seeks responses from companies that can provide these proprietary OEM parts, as the USCG does not own the technical data. Responses must include detailed company information and address specific technical and business capability questions. The closing date for receipt of responses is 1 May 2026 at 12:00pm EDT. No budget, performance location, or solicitation timelines are specified.
