Departure and Initial Climb
The pilot initiated an intersection takeoff with approximately 4,000 feet of runway remaining. He reported that the takeoff proceeded normally through lift-off to about 25 feet above ground level (AGL). From that point, the aircraft descended back to the runway surface and bounced.
Abort and Runway Excursion
Electing to abort, the pilot reduced power. However, the aircraft bounced at least two more times, then veered to the right. It continued off the runway at the departure end, ran down an embankment, and flipped over.
Inspection Findings
An inspection of the elevator trim tab revealed that it was deflected two inches toward a nose-down position. For reference, a full nose-down deflection is 3 3/16 inches, and the tab is in a neutral position when trimmed for takeoff.
Probable Cause
No probable cause was stated in the source.
