Aircraft Accident/Incident Report

Satartia, Mississippi 39162
Saturday, September 11, 1999 17:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot decided to land in an open area next to a soybean field due to a physical urgency. He stated that during the approach, a 'loud noise occurred' and the helicopter became 'uncontrollable,' with the control stick moving forcefully in all directions. Upon impact, the helicopter rolled onto its right side, sustaining damage to the main rotor blades, the tail boom, the skids, and the fuselage. Examination of the helicopter disclosed that the forward engine/transmission mounts had separated from the airframe. Examination of the engine mounts, however, revealed the fracture surface was consistent with overstress separation.

NTSB Probable Cause Narrative

The pilot's failure to maintain control of the helicopter while on approach which resulted in the uncontrolled collision with the ground. A factor was the pilot's physiological condition.
