## Discrepancy

LANDING GEAR DOORS WOULD NOT RETRACT AFTER GEAR UP SELECTED.  RED LIGHTS ON GEAR PANEL WERE ON, GEAR HANDLE LIGHT FLASHING.  THE CREW INDICATED THEY HAVE HAD SIMILAR PROBLEMS WITH THE LANDING GEAR ON THIS AIRCRAFT BEFORE.  THEY REPLACED THE GEAR UPLOCK.  UNABLE TO DUPLICATE PROBLEM ON THE GROUND.  ALL TESTS INDICATE NO PROBLEM WITH SYSTEM.  3 EACH GEAR UPLOCKS CHANGED OUT AS BEFORE.
