## Discrepancy

WHILE ON FLIGHT TO TEST GEAR FOR PREVIOUS LG DISCREPANCY, SDR COEA2015012101807, THE GEAR RETRACTED WITHOUT A PROBLEM.  WHEN THE GEAR WAS PUT DOWN FOR LANDING, THE LT MAIN GEAR INDICATIONS DID NOT INDICATE DOWN & LOCKED.  THE CREW ATTEMPTED TO USE THE EMER EXTENSION SYS WITH NO SUCCESS.  THE GEAR WAS CYCLED & A SECOND ATTEMPT FAILED.  AN EMER WAS DECLARED & A FLY BY THE TOWER WAS PERFORMED TO CHECK IF GEAR WAS DOWN.  TOWER REPORTED GEAR APPEARED TO BE DOWN & LOCKED.  CREW ATTEMPTED TO PUT GEAR DOWN AGAIN, THIS TIME SUCCESSFULLY.  ACFT PERFORMED A NORMAL LANDING. CLEANED & REINSTALLED LT MLG SELF-CLEANING VLV  & ADJUSTED THE LT MLG DOWN LOCK PROXIMITY SWITCHES.  PERFORMED NUMEROUS GEAR CYCLES & MULTIPLE FREE FALL ASSIST TESTS WITHOUT ANY DISCREPANCIES.  OPERATIONS CHECKED GOOD.  ACFT RETURNED TO SERVICE.
