NTSB

The pilot’s failure to maintain airplane control during a water takeoff after an encounter with the wake from a boat.

The pilot’s misjudgment of the airplane’s speed and altitude during the landing approach, and his failure to attain the proper touchdown point during landing, which resulted in a runway overrun. Contributing to the accident were his access to a limited set of flight controls, his obstructed vision due to his seating position, and the pilot’s decision to return to the relatively constrained runway following a perceived anomaly of the airplane’s flaps.

The pilot’s decision to attempt a takeoff from the middle of the runway in shifting wind conditions, which resulted in an aborted takeoff and runway excursion.

The pilot’s inability to regain airplane control after a pilot-induced spin conducted during a flight test, which resulted in a collision with terrain.

The student pilot’s inadequate decision to make a premature turn onto a taxiway which resulted in a collision with a taxiway sign.

The passenger’s inadvertent application of the rear brakes during landing, which resulted in a nose-over.

The pilot’s loss of situation awareness which resulted in landing in a grass area and the subsequent collision with a runway marker.
