Aircraft involved

Probable cause & findings

The pilot's failure to maintain directional control during landing, which resulted in a runway excursion and subsequent impact with trees.

Factual narrative

The pilot of the tailwheel equipped airplane reported that, during landing on a grass strip, the airplane bounced and he performed a successful but "scary" go-around. On the second landing attempt, shortly after touchdown, the airplane bounced again and instead of going around, he "decided to try to save the landing." Shortly after the airplane stopped bouncing, the airplane veered left, exited the runway to the left, and impacted trees. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the wind was 270° at 7 knots. An automated weather observation station located on the airport about 16 NM away, reported that, about the time of the accident, the wind was calm. The pilot landed the airplane on runway 22.
