Incident Overview
A single-engine aircraft, having just completed an annual inspection, was on its first flight back to its home airport. The pilot reported that before takeoff, he observed that the engine would not idle below 850 RPM. Despite this, he elected to continue with the flight.
Takeoff and Abort
During the takeoff roll, the pilot pulled back on the yoke to rotate, but the aircraft did not feel like it wanted to fly. The pilot elected to abort the takeoff but was unable to stop on the remaining runway with the high idle RPM. Subsequently, the aircraft hit a ditch near the end of the runway.
Investigation Findings
An investigation revealed that the elevator trim was in the full nose-down position. No other contributing factors were identified.
