Cessna U206G N206JC accident near Sleetmute, Alaska

Probable cause

The pilot's failure to maintain adequate airspeed during the initial climb after taking off from a wet runway and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.

NTSB analysis

The pilot stated that he was attempting a takeoff from an unimproved, wet airstrip with four passengers on board when the tricycle-geared airplane began to hydroplane, followed by a ground loop, which resulted in substantial damage to the airplane's left wing and tail.

A passenger stated that, after taxiing to the end of the runway and turning around, the pilot began the takeoff roll. After becoming airborne, the airplane immediately turned right, then left, then impacted the trees on the left side of the runway. Following the initial impact, the airplane began to travel backward through the trees.

Photographs of the airplane taken immediately following the accident by the passenger show the flaps in the retracted position, the right main landing gear box protruding through the floorboard of the airplane, and substantial damage to the left wing and fuselage, just aft of the rear window.
