The pilot’s misidentification of the airport’s active runway, which resulted in an off runway landing and a collision with a snow berm. Contributing to the accident was the runway’s lack of identifying markings.

A total loss of engine power during cruise flight due to a fatigue crack in the No. 3 cylinder connecting rod shaft resulting from either preignition or detonation, which resulted in a forced landing and impact with terrain.

The pilots’ failure to maintain adequate airspeed during a simulated power-off approach in gusting wind conditions, which resulted in an exceedance of the airplane’s critical angle of attack, an aerodynamic stall, and loss of control.

The pilot’s inadequate prefight inspection, during which he failed to detect water contamination in the fuel system, which resulted in a total loss of engine power.

The pilot’s failure to maintain a proper glidepath during landing. Contributing to the accident was his failure to ensure the canopy locks were properly configured prior to flight.

The total loss of engine power due to carburetor icing.

The failure of both pilots to see and avoid the other airplane.

The pilot’s inadequate engine hand propping procedure which resulted in the airplane’s unexpected movement and subsequent impact with a fueling station.

A total loss of engine power due to the flight crew incorrectly placing the fuel selector between fuel tank detents, which resulted in fuel starvation. Contributing to the accident was the lack of a placard on the fuel selector, the lack of obvious fuel tank detents in the fuel selector, and the flight crew’s lack of understanding of proper fuel selector operation.
