## Discrepancy

ON PRE-FLIGHT, CREW FOUND LEFT LOWER THRUST REVERSER DOOR HANGING DOWN.  MAINTENANCE FOUND LUGS BROKEN ON BLOCKER DOOR 'BIRDCAGE' ASSEMBLY.  FAILURE DUE TO IMPROPER BOLT ANTI-ROTATION DEVICE INSTALLATION PREVIOUSLY C/W.  BLOCKER DOOR POSSIBLY WOULD HAVE LEFT AIRCRAFT ON NEXT FLIGHT.  THRUST REVERSER ASSY CHANGED.
