Aviation Accident Data Summary - National Transportation Safety Board:

Location: Mansfield, OH
Accident Number: GAA18CA470
Date & Time: 08/06/2018, 1100 EDT
Registration: N454WS
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 1 Minor
Flight Conducted Under: Part 91: General Aviation - Personal


The pilot reported that, during landing, the airplane bounced multiple times, so he added power to go around, but the left wing dropped, and the airplane "veered" left and dropped to the ground. The airplane touched down in the grass to the left of the runway, the nose landing gear collapsed, and the airplane nosed over.

The airplane sustained substantial damage to the fuselage and empennage.

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 exceedance of the airplane's critical angle of attack during a go-around, which resulted in an aerodynamic stall.


Angle of attack - Capability exceeded (Cause)
Landing flare - Not attained/maintained

Personnel issues
Aircraft control - Pilot (Cause)
