## Discrepancy

UPON SELECTING L/G UP, THE NOSE AND RT GEAR RETRACTED.  THE LT MLG UNLOCKED, HOWEVER IT REMAINED IN THE DOWN POSITION WITH BOTH INDICATING SYSTEMS DISPLAYING RED UNLK AND GREEN DOWN TRIANGLE SIMULTANEOUSLY.  ATC TOWER CONFIRMED THE GEAR APPEARED DOWN.  AFTER SLOWING TO 120 KTS, THE GEAR WAS CYCLED DOWN AND THEN RETRACTED NORMALLY.  AT THIS TIME FOUND LT MLG PLUMBING TEE FITTING BROKEN.  REMOVED AND REPLACED TEE FITTING AS PER MM NR 32-31-50 (FIG 16 ITEM NR 50).  PERFORMED EXTENSION AND RETRACTION AS PER JIC NR 32-31-00 AND FOUND SYSTEM WORKING PROPERLY.
