Accident Overview
During a training flight, the instructor simulated an engine failure by pulling the throttle to idle and applying carburetor heat while the airplane was in the pattern for runway 22. The student pilot established an airspeed of 75 miles per hour and turned towards the runway.
Sequence of Events
Approximately 100 feet above ground level (AGL), the airplane encountered a heavy sink rate. The instructor noted that the stall warning horn did not sound and the bank angle was shallow. The student pilot rapidly added power, but the engine did not respond. The airplane subsequently struck the runway on its main landing gear, bounced, and struck the runway again. The impact separated the nose gear, causing the airplane to skid on its nose. A post-impact fire ensued, consuming the fuselage.
Environmental Conditions
The temperature at the time of the accident was 62 degrees Fahrenheit, with a dew point of 32 degrees Fahrenheit. According to the carburetor icing probability chart, these temperature and dew point conditions were on the edge of serious icing conditions at glide power settings.
Probable Cause
No probable cause was stated in the source.
