Aircraft was accepted into the Army Inventory and in February 1980 was assigned to the Sikorsky Development Flight Center in West Palm Beach, Florida and was used to conduct flight testing. Between 4 December 1982 and 26 January 1983, the aircraft was used for the preliminary airworthiness evaluation of the UH-60A configured with the external stores support system (ESSS). On 24 and 25 June 1983 the aircraft was used for a limited preliminary airworthiness evaluation of the UH-60A with GE T700-GE-701A engine installed.

This aircraft was destroyed during an experimental test flight for the adaption of the Vulcan weapons system. While performing a standard level performance test flight for adaption of the Vulcan Weapons System to the UH-60A aircraft, contractor test pilots experienced loss of tail rotor thrust. During deceleration from approximately 150 knots to 130 knots, at 500 feet AGL, the aircraft began a right yaw. The pilot could not correct the right yaw by applying full-left antitorque pedal or by varying airspeed. At 120 feet AGL, both engines were placed in flight idle, and the aircraft was autorotated into 35-foot trees. The aircraft landed hard with no forward motion, coming to rest in an upright position in marshy terrain. Both pilots were injured.
