Probable Cause: The loss of engine power during go-around due to a failed muffler flame tube, which resulted in an exhaust blockage. Contributing to the accident was maintenance personnel’s inadequate inspection of the exhaust system during the most recent maintenance.

Probable Cause The pilot’s failure to maintain clearance from powerlines while maneuvering at a low altitude over water, which resulted in a collision and loss of control.

Probable Cause: The pilot’s mismanagement of fuel, which resulted in fuel starvation and a subsequent total loss of engine power.

Probable Cause: The pilot’s improper preflight planning that resulted in the loss of engine power due to fuel exhaustion.

Probable Cause: The pilot’s inadvertent encounter with helicopter wake turbulence during initial climb, which resulted in a loss of airplane control.

Probable Cause: The pilot’s failure to maintain proper airspeed after liftoff, which resulted in the airplane exceeding its critical angle of attack and an aerodynamic stall.

Probable Cause: A partial loss of engine power as a result of carburetor ice. Contributing to the outcome was the pilot’s failure to effectively use carburetor heat in conditions conducive to the formation of carburetor ice.

Probable Cause: The pilot’s failure to properly secure the left wing fuel cap, which resulted in a loss of engine power due to fuel exhaustion.
