## Discrepancy

DURING GEAR RETRACTION AFTER TAKEOFF, THE RED GEAR UNLOCK LIGHT REMAINED ON.  SOUNDED LIKE THE GEAR RETRACTED NORMALLY.  NO ABNORMAL NOISES OR VIBRATIONS WERE NOTED.  RAN THE STAB MISCOMPARE AND HYD PRESSURE ANNUNCIATOR CHECKLISTS.  THAT DID NOT FIX PROBLEM.  PUT THE GEAR BACK DOWN USING NORMAL PROCEDURES AND RETURNED FOR A NORMAL LANDING.  R & R INTERMITTENT MLG CONTROL HANDLE WITH A REPAIRED UNIT.  DURING OPS CHECK, FOUND RT ENGINE DRIVEN HYD PUMP FAULTY.  R & R DRIVEN PUMP WITH A NEW.  PERFORMED OPS CHECK TO MLG CONTROL HANDLE.  OPS CHECKED GOOD.  RAN RT ENGINE TO OPS AND LEAK CHECK HYD PUMP. OPS AND LEAK CHECKED GOOD.  WORK DONE IAW MM 32-30-01 AND 29-11-03.
