Narrative:

While climbing through FL250 on a flight from bur-sjc it was noticed about 30 NM southeast of the ave VOR that the #1 engine oil temperature had increased into the warning (red) area of the temperature gauge. A level off was requested for FL260 and the power was gradually reduced on #1. The temperature continued to increase to 200 degrees C (the highest temperature on the gauge). It was decided then to shut down the engine and using the appropriate checklists, that was done. Center was advised of the problem and a descent to FL200 was approved. Due to the circumstances of the shutdown, our physical location, the WX, and certain latitudes allowed by our flight manual for the shutdown of one engine on a four engine aircraft, the decision was made to continue to sjc. No emergency was declared and although no special handling was requested, we were shortly thereafter cleared direct to sjc and we landed uneventfully. It was then discovered that oil had leaked into the oil temperature sensor cannon plug causing an erroneous indication that assembly was replaced and the aircraft continued its series of flight south with minimal delay.

Title: ACR MLG INFLT ENGINE SHUT DOWN DUE TO HIGH INDICATED OIL TEMPERATURE.

Narrative: WHILE CLBING THROUGH FL250 ON A FLT FROM BUR-SJC IT WAS NOTICED ABOUT 30 NM SE OF THE AVE VOR THAT THE #1 ENG OIL TEMP HAD INCREASED INTO THE WARNING (RED) AREA OF THE TEMP GAUGE. A LEVEL OFF WAS REQUESTED FOR FL260 AND THE PWR WAS GRADUALLY REDUCED ON #1. THE TEMP CONTINUED TO INCREASE TO 200 DEGS C (THE HIGHEST TEMP ON THE GAUGE). IT WAS DECIDED THEN TO SHUT DOWN THE ENG AND USING THE APPROPRIATE CHKLISTS, THAT WAS DONE. CTR WAS ADVISED OF THE PROB AND A DSNT TO FL200 WAS APPROVED. DUE TO THE CIRCUMSTANCES OF THE SHUTDOWN, OUR PHYSICAL LOCATION, THE WX, AND CERTAIN LATITUDES ALLOWED BY OUR FLT MANUAL FOR THE SHUTDOWN OF ONE ENG ON A FOUR ENG ACFT, THE DECISION WAS MADE TO CONTINUE TO SJC. NO EMER WAS DECLARED AND ALTHOUGH NO SPECIAL HANDLING WAS REQUESTED, WE WERE SHORTLY THEREAFTER CLRED DIRECT TO SJC AND WE LANDED UNEVENTFULLY. IT WAS THEN DISCOVERED THAT OIL HAD LEAKED INTO THE OIL TEMP SENSOR CANNON PLUG CAUSING AN ERRONEOUS INDICATION THAT ASSEMBLY WAS REPLACED AND THE ACFT CONTINUED ITS SERIES OF FLT S WITH MINIMAL DELAY.
