Incident at 45 NM E of Saskatoon, SK

Summary

1999-01-20: WEW 800, a Cessna 414, was enroute VFR from Prince Albert to Regina with 2 crew and 4 passengers and was 45 miles east of Saskatoon (YXE) when the pilot reported shutting down the left engine. He declared an emergency and requested an IFR clearance to YXE. The flight landed without further incident at YXE at 0035Z. The crew reported a loss of oil pressure and a loss of power in the engine prior to shutdown. Maintenance examination on the ground revealed 2 holes in the crankcase, which necessitated replacement of the engine. The engine had operated 1200 hours since overhaul. OPI - Maintenance and Manufacturing UPDATE M. & M. reported that the engine failure was precipitated by a loss of manifold pressure. Maintenance believes this indicates an initial exhaust / intake valve failure, which subsequently caused the camshaft to break and deform the crankcase. Two holes were observed adjacent to the area where the camshaft broke. Maintenance could not confirm a connecting rod failure at this time. The engine has been shipped to the company's overhaul agency for teardown. An SDR has been submitted to Transport Canada.
