## Discrepancy

DURING LANDING GEAR EXTENSION A LOUD BANG WAS HEARD AND THE NUMBER 3 HYDRAULIC QUANTITY DECREASE TO ZERO.  INSPECTION OF THE LEFT MAIN LANDING GEAR REVEALED THE FAILURE OF THE TWO UPPER BOLTS ATTACHING THE RETRACT CYLINDER A BRACKET TO THE AIRFRAME, ALLOWING THE GEAR TO FREE FALL INTO THE LOCKED POSITION, WHICH SEVERED THE HYDRAULIC LINES LEADING TO THE RETRACT CYLINDER CAUSING THE LOSS OF THE NUMBER 3 HYDRAULICS.  REMOVED AND REPLACED THE LEFT MLG RETRACT CYLINDER AND BRACKET.  MAJOR REPAIR TO FITTINGS (P/N ARB06420 AND ARG0272-1), ACCOMPLISHED PER DOUGLAS INSTRUCTIONS.
