On June 23, 2017, about 1315 eastern daylight time, a Hughes 369E, N765KV, operated by Haverfield Aviation Inc, was substantially damaged during a hard landing near Dennis, West Virginia. The commercial pilot was not injured. The external load flight was conducted under the provisions of 14 Code of Federal Regulations Part 133. Visual meteorological conditions prevailed and no flight plan was filed for the local flight.

The pilot reported that he returned to the landing zone with a conductor attached to a long line. The helicopter was in a 100-foot hover over the landing zone, while the pilot monitored a ground crewmember disconnect the conductor from the long line. The helicopter began to settle and the pilot raised the collective control; however, the helicopter continued to settle as a warning horn sounded and the engine noise ceased. The pilot then entered an autorotation and during the landing, a main rotor blade contacted the tailboom, which resulted in a tailboom separation.

Further examination of the helicopter was planned following its recovery to the operator's facility.
