Aircraft Accident/Incident Report

Richfield, Idaho 83349
Tuesady, September 26, 1995 9:45 MDT

NTSB Narrative Summary Released at Completion of Accident

The CFI stated that he pulled the mixture control to idle cut-off to simulate an engine failure. He then closed the throttle and moved the mixture control to full rich, but could not remember using carburetor heat in the descent. According to the student, the airplane descended for 3 to 4 minutes during the simulated emergency. The instructor then attempted to terminate the situation between 100-500 feet agl. The instructor stated that when he attempted to terminate the situation the engine did not respond to power. The airplane then impacted a canal bank and nosed over into the canal. Temperature and dew point values reported both by the pilot and the weather observation facility at Hailey, approximately 28 miles north-northwest, indicated a potential for serious carburetor icing during descent at the time of the accident according to a carburetor ice hazard chart.

NTSB Probable Cause Narrative

The instructor's failure to use carburetor heat during a simulated engine-out descent. Carburetor icing conditions was a factor.
