Abstract
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, A330-200, A330-300, and A340-200, A340-300, A340-500, and A340-600 series airplanes. This AD was prompted by a determination that the service life limits of the cabin pressure control system (CPCS) safety valves installed on the aft pressure bulkhead were being exceeded. This AD requires repetitive replacement of the CPCS safety valves with serviceable valves. We are issuing this AD to prevent exceeding the service life limits of the CPCS safety valves, which, in the event of a failure, could result in excessive positive or negative differential pressure in the fuselage and consequent incapacitation or injuries to airplane occupants.
