Takeoff
The pilot had completed a 30-minute flight, landed, and taxied back for another takeoff. The airplane began its takeoff roll at the maximum allowable gross weight. The pilot initiated rotation at 50 knots, which was 5 knots below the manufacturer's recommended rotation speed.
Incident Sequence
Upon rotation, the airplane pitched up and yawed to the left. The pilot reported that he maintained full engine power and attempted to regain directional control. He stated, "I did not want to change the throttle; I wanted to fly the airplane out of trouble." The airplane subsequently departed the left side of the runway and collided with trees.
Post-Accident Examination
Examination of the airplane revealed that the elevator trim was set in the full nose-up position. The pilot reported no mechanical deficiencies with the airplane.
