The Department of Homeland Security, specifically the U.S. Coast Guard's Aviation Logistics Center, is seeking to procure specific components for the HC144 aircraft, namely two disks and eight retainers. The procurement is intended to be a sole source purchase from General Electric Co., the Original Equipment Manufacturer, due to their exclusive access to the necessary proprietary technical and engineering data. This acquisition is critical for maintaining the operational readiness of the HC144 aircraft, which plays a vital role in the Coast Guard's aviation capabilities. Interested vendors with the requisite expertise are invited to submit their capabilities within ten calendar days of this notice, with a submission deadline set for May 20, 2025, at 4:00 PM EST. For further inquiries, vendors may contact Cayce Copley at cayce.a.copley2@uscg.mil.
