Perimeter DH8A near Berens River on Apr 23rd 2014, one engine shut down in flight, the other seriously leaking oil

A Perimeter Aviation de Havilland Dash 8-100, registration C-GWPS performing flight 4B-107 from Winnipeg,MB to Island Lake,MB (Canada) with 10 people on board, was enroute at FL250 about 170nm northnortheast of Winnipeg when the crew noticed a low oil pressure warning for the right hand engine (PW120) shortly followed by indication of a complete loss of oil pressure on that engine. The crew shut the engine down, turned around to divert to Winnipeg and had the aircraft drift down to 18,000 feet on the way back. While descending through FL210 the crew noticed anomalies in the oil pressure indication for the left hand engine as well, cabin crew reported there was a steady stream of oil visible on the cowling of the left hand engine. A pilot went to visually check the engine and confirmed a substantial oil leak. Being about 50nm southeast of Berens River,MB (Canada) at that time the crew decided to divert to Berens River for an immediate landing. The crew kept the aircraft high and managed a safe landing on Berens River runway 09. The aircraft slowed safely and was about to turn around at the bay at the end of the runway to backtrack and vacate the runway when the aircraft became stuck.

The Canadian TSB reported that the occupants disembarked onto the runway, the runway needed to be closed until the aircraft could be towed off the runway. Maintenance found the right hand engine oil cooler had failed and the left hand engine propeller control unit leaked oil.
