Loss of Control on Ground: Luscombe 8A, N71155, accident occurred January 05, 2019 at Casa Grande Municipal Airport (KCGZ), Pinal County, Arizona

Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Scottsdale, Arizona

Aviation Accident Final Report - National Transportation Safety Board:

Investigation Docket - National Transportation Safety Board:

Location: Casa Grande, AZ

Accident Number: GAA19CA127
Date & Time: 01/05/2019, 1300 MST
Registration: N71155
Aircraft: Luscombe 8
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 Serious, 1 Minor
Flight Conducted Under: Part 91: General Aviation - Personal 


The pilot of the tailwheel-equipped airplane reported that, during landing, as soon as the main landing gear touched down, the airplane yawed left. He tried to correct with right rudder and applied full power for a go-around. During the go-around, the airplane seemed to continue to yaw left, and he attempted to correct with full right rudder, but the airplane continued to drift left, aerodynamically stalled, and subsequently collided with the ground.

The airplane sustained substantial damage to the wings, fuselage, and empennage.

The pilot reported that there were no preimpact 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 yaw control and his exceedance of the airplane's critical angle of attack during an aborted landing, which resulted in an aerodynamic stall.


Yaw control - Not attained/maintained (Cause)
Angle of attack - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Pilot (Cause)
