Overview
During a landing approach, the airplane experienced an unintended descent. The pilot attempted a go-around by applying full power and retracting the flaps. The airplane continued descending, resulting in the left wing contacting the runway. The aircraft then slid left and came to a stop in a ditch.
Pilot Report
The pilot stated that while on final approach with the flaps fully extended, the airplane began sinking. In response, he added full engine power to abort the landing and raised the flaps. Despite these actions, the aircraft continued to sink until the left wing struck the runway surface.
Post-Accident Findings
After the accident, the flaps were found in the retracted (up) position. The aircraft's owner's manual provides guidance for a balked landing (go-around): it instructs that after applying full power, the flap setting should be reduced to 20 degrees immediately. This procedure aims to optimize the climb performance.
Weather Conditions
At the time of the accident, weather records showed no evidence of turbulence, downdrafts, gusts, or windshear. The wind was recorded as blowing from east-northeast at 3 to 4 knots.
