Circumstances:
The flight crew was delivering a cargo of fuel in the four-engine airplane under Title 14, CFR Part 125, when the airplane lost power in the number 2 engine. The captain elected to shut the engine down and return to the airport. He said during the shutdown procedure, the engine caught fire, and that the fire extinguishing system was activated. The crew thought the fire was out, but it erupted again, and the captain elected to land the airplane gear-up on the snow covered tundra. Once on the ground, the left wing was consumed by fire. An inspection by company maintenance personnel revealed that an overhauled engine cylinder had failed at its base, resulting in a fire. The airplane was not examined by the NTSB due to its remote location.
Probable cause:
The failure of an engine cylinder during cruise flight, which resulted in an in-flight fire, and subsequent emergency gear-up landing on snow-covered tundra. A factor in the accident was the failure of the fire suppression equipment to extinguish the fire.

Circumstances:
Aircraft left Norman Wells at 1652LT on a cargo flight to Yellowknife with a crew of four on board. Some six minutes after take off, while climbing, a fire erupted on engine number two. Crew tried to extinguished the fire without success. In the meantime, both propellers on engines number one and two feathered. Captain decided to perform an emergency landing in a snow covered field when fire extingued. He eventually decided to return to Norman Wells where an emergency landing was carried out. After touch down, aircraft veered off runway to the left and came to rest in a snowy field some 60 feet from runway edge. While all four occupants were uninjured, aircraft was considered as damaged beyond repair.
Probable cause:
Engine fire on number two was caused by a fuel leak on a fuel line when fluid fired after contact with high temperature elements.
An Airworthiness Directive published in 1948 mandates the operator to replace the fuel line which was considered as potentially hazardous. Unfortunately, this fuel line was never replaced.
The primary engine fire emergency checklist was unefficient because the procedure to turn off the fuel selector was not required, which contributed to the length of the fire which burned for an extended period of time.
