The Department of Homeland Security, specifically the U.S. Coast Guard, is seeking to procure specific aircraft parts for the HC-144 aircraft through a sole-source contract with Airbus Defense and Space SAU, the Original Equipment Manufacturer (OEM). The procurement includes three support rings, three support assembly rings, and two left-hand handle assemblies, which are critical for maintaining operational safety standards during Product Depot Maintenance. This acquisition is vital for ensuring the continued functionality and safety of the HC-144 aircraft, as the government lacks the technical data to manufacture these parts in-house. Interested vendors must submit their capability information by November 20, 2024, at 4:00 PM EST, and can direct inquiries to Debra W. Heath at debra.w.heath@uscg.mil, referencing solicitation number 70Z03825QL0000019.
