Location: Union City, TN 
Accident Number: ERA20CA048
Date & Time: 12/01/2019, 0700 CST
Registration: N991WS
Aircraft: Cirrus SR22
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries:2 None
Flight Conducted Under: Part 91: General Aviation - Personal

Analysis 

The pilot reported that, while landing, the airplane encountered a crosswind gust and drifted left. At touchdown, a second gust lifted the right wing, the airplane drifted off the runway centerline, and the left wing impacted grass. The pilot added power; however, the left wing continued to drag in the grass, the airplane exited the runway, and the landing gear collapsed. Both wings sustained substantial damage. The pilot reported that there were 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 during landing with a gusting crosswind, which resulted in a runway excursion and the left wing impacting grass.

Findings
