Recent Let L-23 SUPER BLANIK accidents
The pilot’s exceedance of the glider’s critical angle of attack which resulted in a loss of control while maneuvering to return for landing after a runway overshoot.
The flight instructor’s failure to maintain adequate airspeed and his exceedance of the glider’s critical angle of attack, leading to an aerodynamic stall during the off-field landing.
The pilot’s failure to maintain directional control during the landing roll, resulting in an impact with a taxiway sign.
The pilot's encounter with sinking air conditions that resulted in a loss of lift and a subsequent loss of control.
The flight instructor’s lack of remedial action, which resulted in an aerodynamic stall in the landing flare and a hard landing.
The student pilot’s improper landing flare, which resulted in a hard landing and loss of directional control.
The pilot's failure to maintain glider control and his exceedance of the glider's critical angle of attack while maneuvering in gusting wind conditions, which resulted in an aerodynamic stall.
The pilot's encounter with atmospheric conditions that resulted in a loss of lift and a subsequent loss of control near terrain that precluded recovery. Contributing to the accident was the pilot's failure to follow the operator's published tour flight procedures regarding flight over the national park and minimum altitudes over and distance from terrain.
