Incident at 40 NM NW of Saskatoon, SK

Summary

1999-09-09: C-GQXX, a Piper Navajo, was on an IFR flight from Saskatoon (YXE) to Uranium City and was 40 miles northwest of YXE when the pilot reported that the right engine had failed. He advised that he was diverting to Prince Albert, where the flight landed safely at 1802Z. The nature of the engine problem is not known. OPI - Maintenance and Manufacturing UPDATE TSB reported that the pilot observed the right engine manifold pressure drop, followed by the oil pressure reducing to redline values. A passenger also reported smoke coming from the right engine. After securing the engine, the pilot diverted to Prince Albert. Maintenance discovered damage to the bearings of the engine turbocharger. UPDATE M. & M. reported that they contacted the Contract AMO (Elite Aero) regarding the subject CADOR. The DOM stated that the turbocharged shaft failed between the turbine and compressure support bearings. The engine was sent to Aero Recip (engine O/H facility) for internal inspection. Aero recip speculated that Foreign Object Damage (FOD) had been ingested, jamming the compressor and causing the shaft to fail. No FOD could be found to support this conclusion. Inspection of the engine revealed that no internal damage occurred due to the compressor failure. The engine and turbocharger had a total time of 515.1 hours since O/H.
