## Discrepancy

(CAN) AFTER TAKEOFF, WHEN THE LANDING GEAR WAS RETRACTED, THE GREEN DOWN AND LOCKED INDICATION REMAINED ON FOR THE L/H GEAR. THE GEAR WAS CYCLED, BUT THE GEEN INDICATOR REMAINED ON. THE AIRCRAFT RETURNED TO BASE, WHERE IT WAS DETERMINED THAT THE INTERNAL DOWN INDICATOR MICRO SWITCH WAS STAYING ON WHEN THE RAM WAS RETRACTED ON THE MLG ACTUATOR. THE ACTUATOR WAS REPLACED, HYDRAULIC SYSTEM SERVICED, GEAR RETRACTION PREFORMED, AND THE AIRCRAFT RETURNED TO SERVICE.
