Aircraft Accident/Incident Report

Fairbanks, Alaska 99709
Tuesady, September 6, 2005 12:00 AKD

NTSB Narrative Summary Released at Completion of Accident

The private certificated pilot was departing to the north, and downhill, from a one-way landing area, about 2,000 feet msl. The area, oriented north/south, was about 400 feet long, and about 15 feet wide. The pilot indicated that he began the takeoff roll with one notch of flaps selected. The airplane lifted off and climbed to about 40 feet agl. He reported that due to what he believed to be a tailwind, the tail of the airplane felt as if it was pushed downward, raising the nose of the airplane. He lowered the nose to prevent a stall, and began raising the flaps. The airplane collided with spruce trees about 200 yards from the takeoff area, and received damage to the landing gear, stabilizer, both wings and wing lift struts.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate airspeed during takeoff initial climb, which resulted in an inadvertent stall/mush, and subsequent in-flight collision with trees. A factor contributing to the accident was a tailwind.
