Introduction
An accident occurred during an attempted takeoff from a wet, grass runway. The airplane had recently completed an annual inspection and was flown to the owner's location by a pilot-mechanic.
Sequence of Events
According to reports, the owner-pilot entered the airplane with the engines already running and took control from the pilot-mechanic. He then initiated a takeoff. The owner-pilot stated that the airspeed stopped increasing at approximately 60 knots indicated airspeed, leading him to abort the takeoff. During the abort, the airplane slid on the runway for about 1,200 feet. The owner-pilot then attempted to make a right turn onto a taxiway. However, during the turn, the left main landing gear collapsed. The airplane subsequently slid into trees located near the taxiway, resulting in damage to the left aileron.
Post-Accident Examination
Following the accident, an examination of the airplane was conducted. Investigators found dirt and insect larvae inside the pitot tube. The pilot-mechanic, who had performed the preflight inspection prior to the flight, stated that he did not inspect the pitot tube during that inspection.
Probable Cause
The source does not state a probable cause.
