NTSB

Probable cause: The pilot’s selection of an unsuitable landing area, which resulted in the airplane impacting wheat stalks and a subsequent nose-over.

Probable cause: The pilot’s failure to attain a proper touchdown point during landing, which resulted in a runway excursion. Contributing to the accident was the pilot’s impaired vision due to his broken eyeglasses.

Probable cause: The flight instructor’s and pilot’s mismanagement of the available fuel, which resulted in exhaustion of the fuel in the selected fuel tank and a subsequent total loss of engine power.

Probable cause: Innacurate airspeed indications due to contamination of the pitot-static system with insect remains, which resulted in a high approach and landing speed and subsequent runway overrun.

Probable cause: The pilot’s failure to see and avoid trees during low-altitude flight.

Probable cause: The pilot’s loss of runway visibility during landing in rain, which resulted in the pilot’s loss of situational awareness and subsequent loss of airplane control.

Probable cause: The pilot’s failure to maintain an adequate glidepath during approach, which resulted in an impact with a semi-truck.

Probable cause: The pilot’s failure to maintain clearance from terrain while maneuvering at a low altitude. Contributing to the accident was the pilot’s mistaken entry into a canyon surrounded by steep rising terrain while at a low altitude for reason

Probable cause: The flight instructor’s inadequate in-flight fuel management, which resulted in fuel starvation and a total loss of engine power.
