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.
