Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that during landing, as he initiated the flare the airplane began to drift to the left and the left wing dropped. The pilot further reported that he applied full throttle and attempted a "go-around" but was unsuccessful, the left wing impacted the airport perimeter fence and trees, which resulted in substantial damage to the left wing. According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. A review of recorded data from the automated weather observation station located on the airport, revealed that, about 10 minutes before the accident the wind was 290 degrees true at 8 knots. A further review revealed that, about 10 minutes after the accident the wind was 240 degrees true at 5 knots. The airplane landed on runway 02.
