Pilot's Pre-Takeoff Assessment
The pilot stated that prior to takeoff, he inspected a large portion of the frozen lake to determine its suitability for use. He noted that recent rain had left approximately 2 inches of standing water on the ice-covered surface. Despite the standing water, the pilot considered the lake adequate for takeoff.
Takeoff and Accident Sequence
During the takeoff roll, the tail of the airplane lifted, transferring the weight onto the main landing gear. Subsequently, the main wheels encountered water deeper than the pilot had anticipated. This caused the airplane to nose over.
Damage Sustained
The accident resulted in damage to the airplane's wing and lift strut.
