The pilot’s failure to attain a proper soft field takeoff pitch attitude during takeoff that resulted in a runway excursion and subsequent impact with a canal.
NTSB
Pre-buy flight ends in serious injuries for pilot
The pilot’s exceedance of the airplane’s critical angle of attack during the initial climb, which resulted in an aerodynamic stall.
Plane crashes when student locks up on controls
The student pilot’s excessive pitch during takeoff resulted in a loss of control and impact with terrain. Contributing was the student’s failure to relinquish the controls when ordered by the instructor.
Failure of the engine gearbox drive flange leads to forced landing
The failure of the engine gearbox drive flange, which resulted in a nose gear collapse during the subsequent precautionary landing in tall grass.
Pilot’s preflight misses screw in control yoke column
The pilot’s inadequate preflight inspection, which did not detect a screw in the control yoke column, and his failure to confirm flight control continuity before takeoff.
Pilot practicing to become cropduster dies in crash
The pilot’s exceedance of the airplane’s critical angle of attack while maneuvering, which resulted in an aerodynamic stall/spin and loss of control.
Failure to perform a weight and balance calculation proves fatal for two
The pilot’s failure to perform a preflight weight and balance calculation and his operation of the flight at an excessive takeoff weight, resulting in an exceedance of the airplane’s critical angle of attack after liftoff and an aerodynamic stall from which the pilot was unable to recover.
Pilot loses control when landing gear fractures
The pilot’s failure to maintain directional control during a touch-and-go landing after applying power for takeoff, which resulted in a runway excursion and noseover.
Human Factors: Break out the booze
If you think it’s OK for you to drink when you fly, that you can handle it, you are wrong. And if you know someone who drinks before flying, or drinks in-flight, you need to intervene.
