## Discrepancy

WHILE PERFORMING A GEAR RETRACTION CHECK PER A PHASE 2 INSPECTION, THE FOLLOWING PROBLEM WAS NOTED.  UPON SELECTION OF GEAR UP, MAIN GEAR WENT UP AND LOCKED, BUT NOSE GEAR DID NOT.  NOSE GEAR DID COME OFF OF DOWNLOCK, BUT WHEN MAINS WENT UP AND LOCKED, NOSE GEAR STOPPED WHERE IT WAS.  APPARENTLY, THE CONTROL CIRCUIT CONTACTS SHUT OFF BECAUSE THE NOSE UPLOCK SWITCH WAS ALREADY INDICATING UP AND LOCKED EVEN THOUGH NOSE GEAR WAS NOT UP AND LOCKED.  A NEW SWITCH WAS INSTALLED AND THE SYSTEM WORKED NORMALLY.
