Accident Number: WPR20CA134
Date & Time: 04/25/2020, 1200 MDT
Registration: N707VB
Aircraft: Piper PA18
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 Minor
Flight Conducted Under: Part 91: General Aviation - Personal 

The pilot of the tailwheel equipped airplane reported that, she aborted the first landing due to the wind changing direction with slight gusts. During the second landing, as the airplane was rolling out, the pilot applied brakes as the wind simultaneously shifted and lifted the tail of the airplane upward, which resulted in the airplane coming to rest in a nose low attitude. The pilot said that following a momentary pause, another gust of wind lifted the tail and flipped the airplane upside down, near the right side of the runway.

The right-wing lift strut, rudder, and vertical stabilizer were substantially damaged.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
