Accident Summary
During a flight training session, a flight instructor pilot reported a partial loss of engine power while providing instruction in power-off and approach to landing stalls to a dual student. The pilot's attempts to correct the condition were unsuccessful, and he subsequently performed a forced landing. During the landing roll, the airplane nosed over in soft terrain. Weather conditions at the time were conducive to the formation of carburetor ice, with a temperature of 74°F and a dewpoint of 60°F.
Circumstances
The instructor was conducting a training exercise focused on stalls in a power-off configuration and approach to landing. While demonstrating these maneuvers, the engine power partially decreased. The pilot attempted to remedy the situation but could not regain full power. As a result, a forced landing was executed. The airplane touched down and, during the ground roll, the nose dug into soft ground, causing the aircraft to tip forward.
Weather Conditions
Meteorological conditions at the accident site included a temperature of 74°F and a dewpoint of 60°F. According to standard carburetor icing probability charts, these temperature and dewpoint combinations are favorable for the formation of carburetor ice, particularly at lower power settings commonly used during descent and approach maneuvers.
Aftermath
The accident aircraft came to rest in a nose-down attitude in soft terrain. No further details regarding injuries or damage were provided in the initial report.
