NTSB Accidents

The airframe and powerplant mechanic’s lack of experience in the overhaul of the engine model and the improper torque of the crankshaft gear bolt, which resulted in fatigue failure of the bolt and a total loss of engine power during an approach for landing.

The pilot’s failure to maintain yaw control and his exceedance of the airplane’s critical angle of attack during an aborted landing, which resulted in an aerodynamic stall.

The pilot’s distraction and subsequent loss of situational awareness and visual horizon in overcast sky conditions, which led to an unrecognized descent during a low-level maneuver and subsequent impact with snow-covered terrain.

The pilot’s failure to use carburetor heat while operating in conditions conducive to carburetor icing, which resulted in a partial loss of engine power and a subsequent forced landing and impact with a fence.

The pilot’s excessive brake application during the landing roll, which resulted in a runway excursion and collision with a drainage culvert.

The pilot’s improper decision to attempt an aerobatic maneuver at low altitude, which led to an aerodynamic stall and spin from which the pilot could not recover.

The pilot’s loss of control while maneuvering at a low altitude after being struck in the head by a bird.

The pilot’s failure to maintain directional control during the landing roll, which resulted in a runway excursion and impact with a fence.

The failure of the nose landing gear actuator hydraulic hose, which resulted in the loss of hydraulic fluid and hydraulic system pressure and a subsequent gear-up landing.
