## Discrepancy

DURING GEAR EXTENSION GEAR INDICATION WAS THREE RED WITH A FLASHING HANDLE.  GEAR HANDLE WAS CYCLED WITH NO CHANGE TO GEAR INDICATION.  PUTTING GEAR HANDLE IN DOWN POSITION RESULTED IN A NORMAL GEAR INDICATION.  ALL SYSTEMS APPEAR NORMAL.  REPLACED LT MAIN GEAR DOOR ACTUATOR PROXIMITY SWITCH WITH A NEW UNIT IAW F2000 MM 32-600.  OPS + LEAK CHECK GOOD.
