Narrative:
Flight 104 departed Port Hardy for a flight to Comox. No. 2 engine problems forced the crew to turn back to Port Hardy. The engine was shut down and the propeller feathered. The C-46 landed on runway 10 and overran into an area of swamp and tree stumps.
PROBABLE CAUSE: "The right engine failed because of a fatigue fracture of the reduction drive ring gear necessitating feathering of the propeller. Due to the presence of a fog bank, a steep approach was necessary with result that the landing was made at a higher than normal airspeed which, coupled with reduced braking action on the wet runway, caused the aircraft to overrun the landing area."
