## Discrepancy

SHORTLY AFTER DEPARTURE, THE LT WING OVERHEAT LIGHT ILLUMINATED. FOLLOWING PROCEDURE, THE PILOT SHUTDOWN THE LT GENERATOR, LT BLEED AIR AND EXTENDED THE LANDING GEAR. THE LIGHT REMAINED ILLUMINATED SO THE LT ENGINE WAS SHUTDOWN AS A PRECAUTIONARY MEASURE AND THE PILOT RETURNED TO FSD AND MADE AN UNEVENTFUL LANDING. AN INVESTIGATION BY MAINTENANCE COULD NOT REVEAL A CAUSE OTHER THAN A POSSIBLE BRAKE HEATING UP DURING TAXI TO THE RUNWAY OR CABIN TEMP CONTROL SET TO MAX HEAT. MAINTENANCE COULD NOT DUPLICATE.
