Aerodynamic Stall / Spin: Champion 7EC, N815PB; accident occurred March 24, 2019 in Fayetteville, Washington County, Arkansas

Aviation Accident Final Report - National Transportation Safety Board

Additional Participating Entity:

Federal Aviation Administration / Flight Standards District Office; Little Rock, Arkansas

Investigation Docket - National Transportation Safety Board:

Kerzen Properties LLC

Location: Fayetteville, AR
Accident Number: GAA19CA177
Date & Time: 03/24/2019, 1030 CDT
Registration: N815PB
Aircraft: Champion 7EC
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 1 Minor
Flight Conducted Under: Part 91: General Aviation - Personal 


The pilot of the float-equipped airplane reported that, during takeoff from a private lake, the float plane did not "climb as the day before." Upon reaching the end of the lake, he "pulled up hard" on the yoke to avoid power lines, but the "left wing [stalled]," and the float plane impacted the ground.

The float plane sustained substantial damage to both wings and the fuselage.

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, about the time of the accident, the wind was from 190° at 12 knots, gusting to 21 knots. An automated weather observation station about 5 nautical miles from the accident site reported that, about the time of the accident, the wind was from 190° at 11 knots. The airplane departed the lake with a 180° heading.

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 during takeoff as he attempted to avoid power lines, which resulted in an aerodynamic stall. 


Aircraft Angle of attack - Capability exceeded
Personnel issues Aircraft control - Pilot
Environmental issues Wire - Contributed to outcome

  1. PIC failed to abort during takeoff from a private lake, once a predetermined point and time the float plane failed to perform, thus was not as the day before!

  2. “Pulling up hard”, especially in such a drag queen such as this aircraft, would never be good. It leads to quickly loosing airspeed, altitude, and ideas. Leave those kind of control inputs for aerobatic and fighter aircraft
