This is a sources sought notice for market research only and does not constitute a solicitation or a commitment to award. The USCG seeks NAVSUP-approved sources capable of overhauling a hydraulic pump and tail rotor servo and repairing a servo cylinder to OEM specifications, with identified approved sources including Parker Hannifin and Sikorsky Aircraft. Interested firms should provide company contact information, evidence of OEM authorization/approved-source status, business size and socioeconomic classifications, NAICS code, GSA schedule status, relevant government or civilian references, quantity-discount information, and estimated lead time. After reviewing responses, if the USCG proceeds, a solicitation will be published on SAM.gov, and interested offerors must respond separately to that solicitation. Email responses are preferred to Amy Whitehurst at Amy.E.Whitehurst2@uscg.mil.
