Incident at CALGARY INTL AB (CYYC)

Summary

2005-05-18: UPDATE TSB reported that as the Sunwest Home Aviation Piper PA-31-350, registration C-GVAG, operating as CNK 55, was climbing through 6,500 feet after departing Calgary, the flight crew observed that the left engine oil temperature gauge was indicating maximum oil temperature. The cowl flaps were opened, the mixture was selected to full rich and the airspeed was increased to 140 KIAS. The crew advised ATC they were experiencing an engine anomaly and requested priority service for an immediate return to Calgary. As ATC comunication was in progress, the crew also noted that the cylinder head temperature appeared to be climbing towards the yellow. The pilot conducted a teardrop approach to Runway 16 and landed without incident, with the left engine (Avco Lycoming TIO-540-J2BD) shut down. Maintenance examination found a broken wire connector at the oil temperature bulb. The oil temperature bulb was replaced and the aircraft was returned to service. The cylinder head temperature indication was determined to be a normal climb indication.
2005-05-24: UPDATE Maintenance and Manufacturing reported that on climbout from Runway 34 at YYC, the crew noticed the left engine oil temperature was in the red. The crew increased mixture, opened the cowl flaps and lowered the nose. The cylinder head temperature continued to rise so the crew elected to shut down the engine and return to YYC. Maintenance found a broken wire in the right hand oil temperature indication system. The wire was repaired and the aircraft returned to service. Maintenance could not determine the cause of reported increased cylinder head temperature indications.
2005-05-13: CNK 55, a Piper Navajo, departed from Runway 34 at Calgary and approximately 5 NM north of YYC, the pilot informed the Controller that the aircraft was experiencing a mechanical difficulty and requested priority service to return to YYC. CNK 55 landed on Runway 16 after conducting a teardrop approach. The aircraft landed with one engine shut down and taxied under it's own power back to the hangar. TSB will contact the operator.
