Investigation Docket - National Transportation Safety Board:


Location: Huntsville, Arkansas
Accident Number: GAA20CA064
Date & Time: November 9, 2019, 09:45 Local
Registration: N24EP
Aircraft: New Glasair SPORTSMAN GS-2 
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 1 Minor, 1 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The pilot reported that, during the takeoff roll from a wet, turf runway, the airplane encountered mud and veered left. He applied aft pressure to the stick, and the airplane climbed into ground effect. The pilot pulled up and attempted to climb out of ground effect, but the airplane descended and impacted trees. The airplane sustained substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures 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 proper pitch control during takeoff from a muddy, turf runway and his exceedance of the airplane's critical angle of attack during the initial climb, which resulted in an aerodynamic stall. 

Findings

Aircraft Pitch control - Incorrect use/operation
Aircraft Angle of attack - Not attained/maintained
Personnel issues Aircraft control - Pilot
Environmental issues Wet surface - Effect on operation
Environmental issues Tree(s) - Contributed to outcome
