On February 19, 1997, about 0202 eastern standard time, an Enstrom 280C, N51662, was substantially damaged as it impacted the ground after taking off from a field near Lucasville, Ohio.

The helicopter landed in a field about 0155 to pickup a sheriff's deputy, who was to assist as a spotter during the search. Witnesses stated that the helicopter, loaded with the pilot, the sheriff's deputy and another passenger, took off and attained about 5 feet agl. The helicopter landed, the passenger exited, and then, the helicopter took off. It climbed to about 150 feet agl, made a semi-circle or a turn downwind, and traveled approximately 200 feet when it was seen descending vertically into a wooded area.

It was about 50 feet above the trees and he could hear the engine running. He saw the helicopter start to drop and heard it hit the trees. When the EMT's and another deputy arrived at the crash site, the rotor blades were stopped, but the engine was still running. With fuel leaking from the helicopter, the deputy turned off the engine, while the EMT's extracted the occupants from the wreckage.
