Incident at Iqaluit, NWT


1997-10-17: C-GYRS departed Iqaluit for Cape Dorset with the pilot and 2 passengers. Sometime after departure, the pilot saw a slight drop in manifold pressure along with some vibration in one of the engines, followed by the engine quitting. The pilot returned to Iqaluit, and the a/c landed safely at 2059Z. Maintenance is presently examining the engine and will provide more details. UPDATE The engine was taken off the a/c and shipped to Pro Aero Engines in Kelowna for examination. The maintenance staff there indicated that the number 5 cylinder stud broke, which caused a shifting of the cylinder, which in turn caused the fuel injector line to break. The company replaced the crank case and all of the cylinder studs as well as installing a new fuel injector line. The engine was returned to the operator and is now back in service.
