Flight Conducted Under: Part 91: General Aviation - Personal
Analysis
The pilot of a tailwheel equipped airplane reported that, during the second landing, she lost control of the airplane when the tailwheel lifted due to a gust of wind. She added power, but then immediately reduced power due to the airplane drifting. The airplane subsequently departed the runway surface and collided with a fence. The airplane's left wing and forward fuselage were substantially damaged. The pilot reported no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control of the airplane while landing in gusting wind conditions, which resulted in a runway excursion and collision with a fence.
Findings
Aircraft Directional control - Not attained/maintained
Personnel issues Aircraft control - Pilot
Environmental issues Crosswind - Effect on operation
Environmental issues Fence/fence post - Not specified
