Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot/owner stated that, as he began to taxi the airplane, the wind shifted. During takeoff, the airplane reached rotation speed at the midpoint of the runway, but at rotation the airplane would not climb, and the pilot noticed a loss of airspeed but no loss of engine power. Suspecting a shift in wind direction, the pilot aborted the takeoff; however, the airplane overran the departure end of the runway and struck a ditch and an embankment, damaging the nose. According to the pilot, there were no mechanical deficiencies with the airplane prior to the accident. He also reported that the airplane's takeoff weight was 23 pounds below its maximum allowable gross weight.
