Primary finding
Probable cause
The pilot's failure to maintain directional control after an encounter with a windshear during the landing roll, which resulted in a runway excursion.
Investigator assessment
Analysis narrative
The pilot reported that, during the landing roll, the airplane encountered “windshear.” The left wing started to lift, while correcting the right wing impacted the surface. The airplane exited the runway and came to rest on the taxiway. The airplane sustained substantial damage to the right wing. The pilot reported that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operation.
