What was found
WHILE ON CLIMB OUT, THE PILOT NOTICED THAT THE LT WING OVERHEAT LIGHT ILLUMINATED. FOLLOWING PROCEDURE, THE LT GENERATOR WAS SHUTDOWN, BLEED AIR TURNED OFF AND THE LANDING GEAR EXTENDED. AFTER 3 MINUTES THE LIGHT WAS STILL ILLUMINATED AND PROCEDURES CALL OUT FOR ENGINE SHUTDOWN. SHORTLY AFTER ENGINE SHUTDOWN THE LIGHT EXTINGUISHED. THE PILOT INFORMED THE TOWER OF HIS SITUATION AND WAS CLEARED TO RETURN TO WHERE HE MADE AN UNEVENTFUL LANDING. UPON INVESTIGATION, NO EVIDENCE OF FIRE OR OVERHEATING COULD BE FOUND IN THE WING AND GEAR WELL AREAS. IT IS SUSPECTED THAT DUE TO HIGH WINDS DURING THE PILOT’S BACK TAXI TO THE ACTIVE RUNWAY, HE MAY HAVE HAD TO APPLY CONSTANT BRAKE PRESSURE TO KEEP HIS TAXI SPEED LOW. THIS WOULD HAVE CAUSED EXCESSIVE HEATING OF THE BRAKE ASSEMBLY AND ONCE THE GEAR WAS RETRACTED, CAUSED THE WING OVERHEAT LIGHT TO COME ON. IT WAS ALSO REPORTED THAT THE CABIN HEAT WAS SELECTED TO THE FULL HOT POSITION, WHICH MAY HAVE ALSO BEEN A FACTOR.
