The Coast Guard marked an important step in its MH-60T sustainment program when installation, testing and acceptance of the first new wire harness kit were completed Feb. 8. Installation and testing of this first article were conducted at the Coast Guard Aviation Logistics Center (ALC) in Elizabeth City, North Carolina.

The wire harness kit consists of 79 individual, interconnected wire harnesses that provide electrical power and transmit signals for nearly all the aircraft’s systems and subsystems. The wire harnesses are being replaced concurrently with the helicopter hull as part of a program to extend the service life of the Coast Guard’s current fleet of MH-60T helicopters for up to an additional 20,000 flight hours. Wire harnesses installed on the hulls will be a 100 percent form, fit and functional replacement of the existing wiring; they do not increase the overall capability or add new capabilities to the MH-60T aircraft.

TFAB Defense Systems LLC (Tyonek) was awarded a contract for the non-recurring engineering and production of seven wire harness kits in May 2019. Tyonek will deliver the six remaining wire harnesses to the ALC by the end of 2021. The remaining wire harness kits needed to complete the MH-60T sustainment program will be produced and delivered under a future contract.
