## Discrepancy

LEFT MLG GREEN LIGHT REMAINED ILLUMINATED AFTER TAKEOFF.  ALL OTHER GEAR INDICATOR LIGHTS EXTINGUISHED INCLUDING "UNSAFE" LIGHT.  TOWER CONFIRMED LT MAIN GEAR WAS DOWN, EXTENDED.  INSPECTED LANDING GEAR CONTROL VALVE AND FOUND THE PNEUMATIC OVER RIDE POSITION INDICATOR SLIGHTLY OUT OF DETENT.  RESET INDICATOR AND OPERATED GREAR TO VERIFY THE SYSTEM.  REPLACED THE LANDING GRAER CONTROL VALVE.
