The Department of Homeland Security, specifically the U.S. Coast Guard's Aviation Logistics Center (ALC), is conducting market research for a portable, rugged, and compact Modular System Test Set for the MH-60T helicopter. This test set is required to verify the operational status of aircraft systems and isolate faults during Class D and Class C-level maintenance, replacing obsolete test sets and ensuring the validation of critical engine and fuel indication parameters. The test set must be man-portable, capable of operating in the field, and modular for future upgrades, with specific functionalities including resistance checks and oxidation removal for de-ice systems. Interested vendors should submit their capabilities statements and relevant company information to Trenton Twiford at trenton.c.twiford@uscg.mil or the MRR Procurement Mailbox at mrr-procurement@uscg.mil, as no solicitation currently exists and responses will inform future procurement actions.
