NTSB Narrative Summary Released at Completion of Accident

The experimental amateur built airplane collided with trees during a forced landing following a go-around on runway 18 (1,000 feet by 20 feet, grass). The pilot stated he was not happy with the approach so he initiated a go-around from an altitude of about 15 feet above the ground. He reported the engine only produced about 4,000 rpm instead of the normal 5,300 rpm when he applied full power. The pilot reported he was unable to sustain a climb with the reduced power and the airplane settled into trees in a wooded area off the south end of the airstrip. The airplane was powered by a Rotax 912 UL, 80 horsepower engine. The engine had accumulated about 100 hours when the pilot purchased it with an additional 2 hours since it was installed on the accident airplane. On the NTSB Form 6120.1/2, the pilot reported there were no mechanical malfunctions or failures.

NTSB Probable Cause Narrative

A partial loss of engine power for undetermined reasons.
