Aircraft Accident/Incident Report

Gulkana, Alaska 99695
Tuesady, February 13, 2007 15:30 AST

NTSB Narrative Summary Released at Completion of Accident

The pilot of the ski-equipped airplane was taking off on a snow-covered lake for a visual flight rules (VFR) local flight under Title 14, CFR Part 91. The pilot said during takeoff he felt the airplane was not accelerating fast enough to climb over the trees at the end of the takeoff area. He closed the throttle to abort the takeoff, and the airplane slid into the trees. He said there were no known mechanical problems with the airplane during earlier flights that day, but he felt the engine may not have been producing full power during the accident takeoff. The airplane sustained structural damage to the wings and fuselage. The airplane was not examined by the NTSB, and the pilot did not provide additional information regarding what may have precipitated the loss of engine power.

NTSB Probable Cause Narrative

The partial loss of engine power for an undetermined reason during takeoff, which resulted in an aborted takeoff and collision with trees.
