Takeoff and Abort Sequence
According to the pilot, all engine and flight indications were in the "normal range" during the takeoff roll on a 2,400-foot turf runway. The aircraft was accelerating normally into a headwind of 6 to 8 knots. Approximately halfway down the runway, the aircraft attained "2/3 flying speed." Between that point and the end of the runway, the aircraft became airborne but then settled back onto the runway surface.
At that point, the pilot decided to abort the takeoff. He reduced power and applied braking. However, he realized that the aircraft would not be able to stop before impacting a berm located at the end of the runway. The pilot then added full power, and the aircraft cleared the berm.
Impact and Final Resting Place
After clearing the berm, the aircraft crossed a dirt road, then impacted a tree and some boulders. It came to rest in a pond. The pilot stated that no mechanical malfunctions were detected during the event.
Environmental Conditions
The pilot reported that it had rained earlier in the day and that the runway might have still been damp. No other environmental factors were noted in the pilot's account.
Summary
The event involved an aborted takeoff on a turf runway, followed by an unsuccessful stop, resulting in the aircraft striking obstacles and coming to rest in a pond. The pilot cited normal indications and no mechanical issues, and mentioned possible damp runway conditions from earlier rain.
