NTSB

Probable cause: The partial loss of engine power due to carburetor icing.

Probable cause: The student pilot’s failure to maintain clearance from other airplanes in the run-up area.

Probable cause: The pilot’s failure to maintain airplane control during the final approach to the runway in gusting tailwind conditions, which resulted in the airplane exceeding its critical angle of attack and an aerodynamic stall.

Probable cause: Company maintenance personnel’s failure to remove a screwdriver that was left lodged in the windshield wiper area of the forward fuselage during maintenance and subsequently became dislodged on takeoff/initial climb and collided

Probable cause: The flight instructor’s failure to review the notices to airmen related to the airport, which resulted in his landing on a closed runway and the airplane striking runway closed markers.

Probable cause: The pilot’s inadequate preflight inspection, during which he failed to ensure that there was sufficient coolant in the engine reservoir, which resulted in the engine getting too hot and the engine control module shutting down the engine.

Probable cause: The pilots’ decision to perform flight training maneuvers at low airspeed at an altitude that was insufficient for stall recovery. Contributing to the accident was the flight instructor’s inappropriate use of non-standar

Probable cause: The pilot’s failure to maintain directional control during a go-around.

Probable cause: The pilot’s failure to shut down the engine before exiting the airplane and his failure to focus his attention on the task at hand, which led to his walking into a rotating propeller.
