Incident Overview
Description
The Bristol 170 took off from Edmonton at 00:21 MST for an IFR flight to Yellowknife. Within the Edmonton Control Area the crew had to maintain VFR however. Around 00:43 the radioed that they were experiencing problems because of a failure of the no. 2 engine and that they were returning to Edmonton at an altitude of 3000 feet. Nothing more was heard from the flight. It appeared the aircraft had crashed in a farm field. PROBABLE CAUSE: “For reasons as yet undetermined the starboard engine failed and as a result of being overloaded, the aircraft did not maintain altitude on one engine and struck the ground with the starboard wingtip. A further contributory factor was considered to be the failure of the co-pilot’s vacuum-driven gyro instruments, without his knowledge.”
