Aircraft Accident/Incident Report

Lodi, California 95220
Wednesday, January 1, 1992 14:20 PST

NTSB Narrative Summary Released at Completion of Accident

WEATHER CONDITIONS ALONG THE AIRCRAFT'S FLIGHT ROUTE WERE CONDUCIVE TO CARBURETOR ICING. THE PILOT ENTERED AN AUROTATIVE DESCENT WITHOUT APPLYING FULL CARBURETOR HEAT AS RECOMMENDED BY THE AIRCRAFT MANUFACTURER. THE ENGINE FAILED DURING THE DESCENT AND THE HELICOPTER LANDED HARD AND ROLLED OVER ON ITS SIDE. THE PILOT HAD RECEIVED MOST OF HIS FLIGHT EXPERIENCE IN TURBINE POWERED HELICOPTERS.

NTSB Probable Cause Narrative

THE PILOT'S IMPROPER USE OF THE CARBURETOR HEAT CONTROL AND DELAY IN FLARING THE HELICOPTER FOR AN AUTOROTATIVE TOUCHDOWN. CARBURETOR ICING CONDITIONS AND THE SOFT TERRAIN WERE CONTRIBUTING FACTORS IN THE ACCIDENT.
