Investigation Docket - National Transportation Safety Board:

Location: York, SC
Accident Number: GAA19CA416
Date & Time: 07/15/2019, 1400 EDT
Registration: N987TW
Aircraft: Thomas Wild AVID
Aircraft Damage: Substantial
Defining Event: Miscellaneous/other
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 


The pilot reported that he was transitioning to a new airplane. He stated that, during takeoff, it was the first time with his left hand on the control stick and right hand on the throttle. About 10 ft above the runway, he intended to pitch the nose up to initiate a climb. However, he inadvertently pulled back on the throttle control with his right hand. The airspeed decreased, the left wing aerodynamically stalled, and the airplane impacted an adjacent corn field.

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 inadvertent reduction of power during the initial climb, which resulted in an aerodynamic stall. Contributing to the pilot's inadvertent reduction of power was his lack of experience with his left hand on the control stick and right hand on the throttle.


Angle of attack - Capability exceeded (Cause)

Personnel issues

Incorrect action performance - Pilot (Cause)
