REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
During the Installation of the Intrusion and Penetration Resistant Cockpit Door,
it was found that the electrical harness 7450VB, installed on the cover of the
upper cockpit door frame, is accessible from the cabin side. Therefore, the
protection of this harness must be improved.
This Service Bulletin introduces :
— a re-routing of the electrical harness 7450VB,
— the installation of a protection plate for the electrical harness 7450VB.
This Service Bulletin has been validated on A340-600 aircraft MSN 0436.
Accomplishment of this Service Bulletin improves cockpit security by eliminating
the possibility of access to the electrical harness from the cabin side.
