Date & Time: 01/27/2019, 1122 AKS
Registration: N6716B
Aircraft: Piper PA22
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Instructional

Analysis 

The student pilot reported that, on her first solo flight and during a second touch-and-go landing, shortly after touchdown, the airplane "started sliding" right. She added that she overcorrected with "excessive" left rudder. Subsequently, the airplane exited the left side of the runway, impacted a snowbank, and nosed over.

The airplane sustained substantial damage to the empennage.

The student 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 student pilot's overcorrection with rudder during the landing and her subsequent failure to maintain directional control, which resulted in a runway excursion, impact with a snowbank, and a nose-over.
