Event Summary
A pilot with 716 hours of total flight time reported an uneventful cross-country flight. During the approach, the pilot established a wide base leg for the runway, applied carburetor heat, and reduced engine power. While descending, the pilot added power several times to prevent spark plug fouling.
Landing and Takeoff
After a normal touch-and-go landing, the pilot noted that all engine instruments were indicating in the green range and proceeded with the takeoff. At approximately 300 feet above ground level, the pilot observed a large drop in engine rpm, and the airplane became unable to maintain altitude.
Pilot Actions and Outcome
In response, the pilot pushed the nose over and landed straight ahead. The pilot performed a forced landing in an open area ahead. The airplane sustained minor damage during the landing.
Investigation
The reason for the loss of engine power was undetermined. The investigation did not identify any mechanical anomalies or other contributing factors.
