Tuesady, April 28, 1992 12:30 CDT

NTSB Narrative Summary Released at Completion of Accident

THE CFI STATED HE INITIATED A CLIMBING RIGHT TURN JUST AFTER LIFT-OFF. HE ESTIMATED THE HELICOPTER WAS ABOUT 10 TO 15 FEET ABOVE THE GROUND WHEN '...IT FELT LIKE THE HELICOPTER LOST POWER AND TRIED TO YAW TOWARDS THE LEFT....I TRIED TO GET IT BACK ON THE GROUND AS QUICKLY AND SAFELY AS I COULD.' HE STATED HE OVERCOMPENSATED FOR A PERCEIVED 'UPWARD PRESSURE' ON THE COLLECTIVE, AND THE HELICOPTER IMPACTED THE GROUND ABRUPTLY. WEATHER CONDITIONS WERE CONDUCIVE FOR MODERATE CARBURETOR ICING. THE STUDENT PILOT (GROUND WITNESS TO THE ACCIDENT) REPORTED THE CFI MADE A NUMBER OF ADJUSTMENTS TO THE CARBURETOR HEAT DURING THE PREVIOUS FLIGHT. EXAMINATION REVEALED NO EVIDENCE OF PRE-IMPACT MECHANICAL MALFUNCTION.

NTSB Probable Cause Narrative

THE HELICOPTER PILOT'S ABRUPT TOUCHDOWN DURING THE FORCED LANDING. RELATED FACTORS WERE THE PRESENCE OF CARBURETOR ICE CONDITIONS, AND THE PILOT'S IMPROPER USE OF CARBURETOR HEAT.
