What happened
Shortly after initiating takeoff, the pilot reported a sudden loss of engine power. Unable to maintain altitude or continue the climb, the pilot was forced to execute an emergency landing in a field of weeds located near the runway. The aircraft sustained damage during this ground contact event.
The investigation
Following the accident, investigators conducted a thorough examination of the aircraft's engine. The mechanical inspection revealed no discrepancies or pre-existing mechanical failures that would explain the power loss. The engine components appeared to be in normal working order from a structural and functional standpoint.
Findings
Weather conditions at the time of the incident were characterized by a temperature of 36 degrees Fahrenheit and a dew point of 31 degrees Fahrenheit. These specific atmospheric conditions are known to create a high risk for carburetor icing. According to aviation charts detailing conditions favorable for carburetor icing, this combination of temperature and dew point indicates that serious icing is likely to occur at cruise or climb power settings.
The investigation concluded that the engine failure was not due to mechanical defect but rather environmental factors. The pilot encountered carburetor icing during the climb phase, which restricted fuel-air mixture flow and led to the loss of power.
