Factual narrative

The pilot reported that during landing he was slow to react when the wind lifted the airplane’s right wing. The airplane subsequently ground looped and came to a stop in the grass median between the runway and the taxiway. The airplane sustained substantial damage to the fuselage and vertical stabilizer. The pilot reported that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the pilot was landing on runway 01 with wind from 060o at 9 knots.

Probable cause

The pilot’s failure to maintain directional control during landing with a crosswind. The National Transportation Safety Board determined the probable cause of this accident.
