Aircraft Accident/Incident Report

Rawlins, Wyoming 82301
Friday, September 22, 2000 13:30 MDT

NTSB Narrative Summary Released at Completion of Accident

During a local flight to pick up personnel, the helicopter was launched during a snowstorm. The weather was moderate snow, partial obscuration, 1/4-mile visibility, winds from 320 degrees at 12 knots with gusts to 20 knots, and a temperature/dew point of 28/27 degrees Fahrenheit respectively. Limitations in the flight manual require that both a particle separator and deflector be installed on the engine for flight in snow to prevent engine flame out. A deflector was not installed. During cruise flight at approximately 200 feet above ground level, the engine lost all power and the pilot performed a downwind autorotative landing. During the flare for landing, the pilot lost ground contact due to blowing snow and the helicopter picked up a right drift. During touchdown, the helicopter rolled on its side.

NTSB Probable Cause Narrative

The company dispatching, and the pilot initiating, flight into known adverse weather with an aircraft which did not have the required anti-ice equipment installed. A factor was snow conditions.
