Probable cause: The partial loss of engine power due to a fractured exhaust valve, which resulted in a forced landing on unsuitable terrain and a subsequent rollover.

Probable cause: The pilot’s improper preflight fuel planning and in-flight fuel management, which resulted in fuel exhaustion and the total loss of engine power.

Probable cause: The pilot’s improper decision not to abort the takeoff after the airplane encountered standing water on the runway, which decreased its speed and led to its subsequent inability to climb and resulted in a runway overrun.

Probable cause: The airplane’s collision with a bird during straight-and-level flight.

Probable cause: The pilot’s failure to see and avoid power wires while maneuvering at low altitude. Contributing to the accident was the pilot’s inability to determine the airplane’s altitude due to sun glare.

Probable cause: The partial loss of engine power during the initial climb due to a sticking intake valve on the No. 3 cylinder.

Probable cause: The pilot’s exceedance of the airplane’s critical angle of attack while maneuvering for landing, which resulted in an aerodynamic stall.

Probable cause: The pilot’s improper preflight planning that did not identify the unserviceable runway; his subsequent decision to attempt to takeoff from the rough, grassy runway; and his selection of an abort point with insufficient runway remaining, which resulted in a runway overrun.

Probable cause: A loss of engine power due to carburetor icing, the pilot’s decision to turn back to the runway shortly after takeoff, and his failure to maintain airspeed during the turn, which resulted in an exceedance of the airplane’s critical angle of attack, and subsequent aerodynamic stall.
