The 38-hour student helicopter pilot stated he intended to practice hovering maneuvers over a grass apron adjacent to a taxiway at the airport.

The main rotor blades of the experimental single-engine helicopter were destroyed when the helicopter came to rest on its right side. The pilot, who held a private certificate in airplanes single-engine land, reported he had accumulated a total of 1,986 hours. In a narrative statement submitted by the pilot he added that "the accident was due solely to pilot error and did not involve any other aircraft, person, vehicles, or property."
