NTSB

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.

Probable cause: The pilot’s loss of airplane control for reasons that could not be determined due to a lack of evidence.

Probable cause: An in-flight collision with a bird.

Probable cause: The failure of the fuel selector valve in a position that restricted fuel flow to the engine, resulting in a total loss of engine power during initial climb due to fuel starvation.
