NTSB Narrative Summary Released at Completion of Accident

The flight instructor noticed the engine was losing power and turned on the carburetor heat and increased the throttle to full power. After 30 seconds, there was no increase in engine performance and the instructor decided to conduct a forced landing into a field. Upon landing in the soft field, the nose gear collapsed and the airplane came to rest on its nose. The instructor reported no mechanical malfunctions with the airframe or engine and said she suspected carburetor ice. The instructor reported a broken layer of clouds at 2,800 feet msl. Also, she noted at 2,000 msl, the temperature was 60 degrees Fahrenheit with a relative humidity between 55 to 59 percent. The closest weather reporting station was noting a surface temperature of 66 degrees and a dew point of 41 degrees. According to a carburetor icing probability chart, these conditions were conducive for moderate icing at cruise power and serious icing at descent power.

NTSB Probable Cause Narrative

a partial loss of engine power due to carburetor icing conditions.
