was on an IFR flight to Edmonton City Centre airport from Winnipeg, and about 47 miles southeast of Yorkton at 2331Z, the pilot informed ATC that he had to shut down the right engine and feather the prop. He also advised that the a/c was unable to maintain the flight planned altitude of 10,000 feet and was descending through 9,000 feet. The pilot requested a diversion to Yorkton (YQV), and ACC issued a revised clearance for an approach into YQV. The pilot was offered CFR, but indicated he did not require it. C-GSBW
arrived on Runway 30 at YQV at 0008Z. The pilot had some difficulty taxiing the a/c on one engine, and reported clear of all runways at 0016Z. There was no operational impact for other a/c. More details will follow. UPDATE A local maintenance shop at YQV determined that the engine had suffered a failure within the accessory gears of the right engine. The a/c owner's maintenance facility will submit a Service Difficulty Report to Transport Canada.
