Overview
A pilot reported that fatigue and overconfidence played a role in an accident that occurred during a takeoff from a small lake. The lake, approximately half a mile in length, was oriented on an east–west heading. The pilot elected to take off despite a crosswind.
Takeoff Sequence
During the crosswind takeoff, the pilot experienced difficulty getting the aircraft to lift off but decided to continue the takeoff attempt. The aircraft eventually lifted off but then failed to accelerate sufficiently while still in ground effect. Subsequently, the aircraft mushed into a tundra hill while it remained in ground effect.
Pilot's Assessment
The pilot stated that he was fatigued and overconfident in both himself and the aircraft. He indicated that he should have waited until the wind was aligned with the lake's axis, or alternatively, repositioned the aircraft to a larger lake before hauling the cargo. No other factors were cited by the pilot.
