Narrative:
After departing mankato airport, I noticed the right engine cylinder head temperature was near the redline, but the oil temperature/pressure indications were normal. I told the controller I would like to return to mkt for landing to check it out, and I was cleared for the visual approach. Upon landing, the needle returned to a normal position. On the ground I did an extended run up of the right engine, and all gauges read normal. I viewed it as a stuck needle, and not an engine problem. I then got a new clearance, and departed the airport. The high temperature indication was not repeated and the flight was completed without further incident.

Title: PLT OF AN ATX TWIN RETURNED TO LAND AFTER THE CYLINDER HEAD TEMP ON ONE ENG WAS NEAR REDLINE.
Narrative: AFTER DEPARTING MANKATO ARPT, I NOTICED THE R ENG CYLINDER HEAD TEMP WAS NEAR THE REDLINE, BUT THE OIL TEMP/PRESSURE INDICATIONS WERE NORMAL. I TOLD THE CTLR I WOULD LIKE TO RETURN TO MKT FOR LNDG TO CHK IT OUT, AND I WAS CLRED FOR THE VISUAL APCH. UPON LNDG, THE NEEDLE RETURNED TO A NORMAL POS. ON THE GND I DID AN EXTENDED RUN UP OF THE R ENG, AND ALL GAUGES READ NORMAL. I VIEWED IT AS A STUCK NEEDLE, AND NOT AN ENG PROB. I THEN GOT A NEW CLRNC, AND DEPARTED THE ARPT. THE HIGH TEMP INDICATION WAS NOT REPEATED AND THE FLT WAS COMPLETED WITHOUT FURTHER INCIDENT.
