Location: Flanigan, NV

Accident Number: WPR19TA018
Date & Time: 11/03/2018, 1000 PDT
Registration: N13NZ
Aircraft: Audenried Kitfox S7 SuperSport
Aircraft Damage: Substantial
Defining Event: Abrupt maneuver
Injuries: 1 Serious
Flight Conducted Under: Part 91: General Aviation - Personal 

Analysis 

The commercial pilot reported that he took off from a dry lake bed with a second airplane for people on the ground to visually compare the two. After a normal flight, the second airplane landed. The pilot flew past the landing spot, pulled into a nose-high attitude, and made a rapid left turn. He pushed on the left rudder control, and the left wing stalled. The pilot attempted to recover from the stall; however, the airplane was at too low of an altitude to recover, and it impacted the ground in a nose-low attitude. The pilot reported no mechanical failures or malfunctions with the airplane that would have precluded normal operation. It is likely that the pilot failed to maintain airspeed during the sharp turn, which resulted in an aerodynamic stall. 

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 airspeed during a sharp turn at low altitude, which resulted in an aerodynamic stall.

Findings

Aircraft
Airspeed - Not attained/maintained (Cause)
Angle of attack - Not attained/maintained (Cause)

Personnel issues
