Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340-200, and A340-300 series airplanes. This AD was prompted by a report that the auxiliary power unit (APU) aft fuel pump printed circuit board (PCB) varnish had deteriorated; the varnish is one of the layers of protection against development of an ignition source. This AD requires replacing each affected APU aft fuel pump, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
