Stockmar Airport
Aircraft Accident/Incident Report

Villa Rica, Georgia 30180
Wednesday, May 13, 1998 16:30 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that while in cruise flight he experienced a vibration/buzz sound. He set up for a precautionary, run-on landing to the nearest airport's single runway. When he realized the runway was in use, he elected to land onto an adjacent, grassy area. The left skid collided with a rock, the helicopter experienced a loss of directional control, yawed counterclockwise, and the main rotor blade severed the tailboom.

NTSB Probable Cause Narrative

The pilot's choice of landing area during a precautionary landing adjacent to the runway. This resulted in an in-flight collision of the left skid with a rock during a cyclic flare, loss of directional control, and subsequent collision of the main rotor blade with the tail boom.
