Aircraft Accident/Incident Report

Yuma, Arizona 85365
Thursday, May 2, 1996 10:22 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he was proceeding eastbound about 50 feet above ground level, when something on the ground got his attention. He initiated a left turn, then started a sweeping right turn to position the helicopter for a better obversation of tracks on the ground. The wind at that time was estimated to be variable from southeast to the south-southwest at 20 mph with gusts to 25 to 30 mph. The pilot reported that during the last stage of the right turn, he lost control of the helicopter, and it collided with the ground. The pilot remembered that the helicopter fishtailed and porpoised before it impacted. Also, there was no reported mechanical problem before the accident, nor was the rotor rpm determined before impact.

NTSB Probable Cause Narrative

failure of the pilot to maintain control of the helicopter, while maneuvering close to the ground. The unfavorable wind condition was a related factor.
