Narrative:The pilot said he performed a preflight inspection, engine start, run-up, and magneto check with no anomalies noted. He said he taxied the airplane to the approach end of the 2,300-foot grass strip for a departure to the east. The field elevation was 550 feet, and the density altitude was 1,800 feet. According to the pilot, the airplane performed as expected through the ground roll and initial climb, but that the airplane appeared to lose power and mushed into the trees at the departure end of the runway. Interpolation of performance charts revealed that the airplane was capable of a departure from a grass strip that length, and under those atmospheric conditions, at its maximum allowable gross weight. Post-crash examination of the engine revealed the exhaust valve in the #1 cylinder was stuck in the open position.
Probable Cause: The loss of engine power over unsuitable terrain due to an exhaust valve stuck in the open position.
