## Discrepancy

DURING RETROFIT OF HYDRUALIC MODULE FRAME, LEFT OR FORWARD WALL, BRACKET WAS FOUND CRACKED.  CRACKS WERE NOT DETECTABLE UNTIL BRACKET WAS COMPLETELY REMOVED.  CRACKS APPEARED TO BE STARTING FROM CENTER EDGE OF RIVETED NUTPLATES.  SUBMITTER STATED THIS BRACKET GENERIC TO ALL 105 HELICOPTERS, HAD SAME BRACKET CRACK ON CBS4 VARIANT, BUT AT A MUCH HIGHER TIME, 2,200 HRS.  EUROCOPTER IS SUPPOSED TO COME OUT WITH OPTIONAL BULLETIN TO ADDRESS CRACKING ON FORWARD WALL OF HYDRAULIC MODULE.
