Investigation Docket - National Transportation Safety Board: https://dms.ntsb.gov/pubdms


Location: Goddard, KS
Accident Number: GAA20CA015
Date & Time: 10/13/2019, 1430 CDT
Aircraft: Taylorcraft BC12
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal


The pilot reported that, during takeoff, the airplane lifted off and that he felt "a strange push," and the airplane drifted left toward some hangars. He made corrections toward the runway centerline, and the airplane felt "mushy." The airspeed decreased, so he lowered the nose to increase the airspeed. The airplane then stalled, impacted a soft field, and came to a sudden stop. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot added that the wind was 7 to 10 mph from the south-southeast and shifted to 7 to 10 mph from the north-northeast. The pilot departed from runway 18. 

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, which resulted in an aerodynamic stall. 


Angle of attack - Capability exceeded (Cause)

Personnel issues
Aircraft control - Pilot (Cause)

Environmental issues
Variable wind - Effect on operation
