. Reason: O n a production aeroplane , i t has been discover ed that wires in harness 5877VB , installed in the Tail Cone (Section 19 .1 ) and connected to the A uxiliary P ower U nit starter, have a section smaller than required by design. Section 19 is a flammable fluid leakage zone, adjacent to a fuel tank (trim tank) and is open with Section 19.1. The results of the i nvestigation show that this issue is a manufacturing quality issue

. Airbus identified a list of other aeroplanes that are affected

. This condition, if not corrected, could damage the wiring which may create an ignition source in an area that may contain fuel vapours, possibly resulting in an uncontrolled fire and subsequent loss of the aeroplane. To address this potential unsafe condition, Airbus developed Service Bulletin (SB) A330

- 9 2

- 3 116 for aeroplanes in service. For the reasons described above, this AD requires the replacement of the affected wiring harness
