## Discrepancy

LEFT LANDING GEAR WOULD NOT REMAIN IN UP AND LOCKED POSITION AFTER TAKEOFF, LANDING NORMAL SINK RATE.  OVERWEIGHT LANDING 114.9.  REMOVED AND REPLACED LEFT INBOARD MAIN LANDING GEAR UPLOCK ACTUATOR, AND LUBED LEFT MAIN LANDING GEAR PER AMM 32-32-41.  OPERATIONAL CHECKS GOOD, OK TO CONTINUE.
