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 Information
Registered Owner (Historical)
Analysis
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 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 21 knots. An automated weather observation station, about the time of the accident, about 5 nautical miles from the accident site, reported the wind was from 190° at 11 knots. The airplane departed the private lake with a 180° heading.
