Unsafe Condition
The bonding lead from the isolation valve 283HN to Frame (FR) 64, between Stringer (STGR) 33 and STGR 34, is too close to the electrical harness 5871VB, which may cause chafing. This chafing could lead to a short circuit of the isolation valve and consequent non-closure, preventing air flow shutdown in case of fire.

Required Actions
Install a new bonding bracket and new bonding lead at STGR33, between FR64 and FR65, as introduced by Airbus modification 201500 or 201681 in production, or as specified in Airbus Service Bulletin A330-21-3165, A330-21-3160, or A340-21-4152 in service. For airplanes already modified with these SBs, additional wiring connected to the airplane's structure must be accomplished.
