The pilot’s failure to maintain adequate airspeed while maneuvering to avoid mountainous terrain, which resulted in the airplane exceeding its critical angle of attack and an aerodynamic stall.

The pilot’s failure to maintain directional control during the landing roll, which resulted in a ground loop.

The pilot’s failure to maintain clearance from wires during an agricultural application flight.

The student pilot’s improper decision to turn off the runway while the airplane was moving too fast after landing, which resulted in a runway excursion and impact with a taxiway sign.

The pilot’s inability to land on the runway in dark night conditions with reported smoke in the cockpit, which necessitated the deployment of the airplane’s parachute system.

The pilot’s exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.

The pilot’s failure to properly secure the seat before takeoff, which resulted in it sliding back during takeoff and rendering him unable to reach the rudder pedals and throttle lever, a subsequent runway excursion, ground loop, and impact with a berm.

The pilot’s improper fuel planning, which resulted in fuel exhaustion, a total loss of engine power, an off-airport landing to a field, and a subsequent nose-over.

The pilot’s abrupt maneuver to try and avoid a deer during landing on a grass strip runway, which resulted in a ground loop.
