Aviation Accident Data Summary - National Transportation Safety Board:

Location: Bentonville, AR
Accident Number: GAA18CA549
Date & Time: 09/12/2018, 1830 CDT
Registration: N868X
Aircraft: Aviat A1
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 tailwheel-equipped airplane bounced. The airplane then bounced again twice and veered left of the centerline, and he applied "stick back" to pin the tail down. He then applied full throttle to go around but did not relieve the back pressure on the stick. Subsequently, the airplane pitched up in a "very high" angle of attack, which resulted in an aerodynamic stall and spin and subsequent impact with the ground.

The airplane sustained substantial damage to the fuselage.

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 an attempted go-around after the airplane bounced, which resulted in an aerodynamic stall.


Angle of attack - Capability exceeded (Cause)

Personnel issues
