Airworthiness Directive · Amendment 39-18295 · Airbus Airplanes
Airbus Airplanes
This AD applies to the airplanes specified in paragraphs (c)(1) and (c)(2) of this AD.
(1) Airbus Model A330-243, -341, -342, and -343 airplanes, certificated in any category, all manufacturer serial numbers equipped with Rolls-Royce Trent 700 engines, on which Airbus Modification 56966MP16199 has been embodied in production or Airbus Service Bulletin A330-28-3105 has been embodied in service.
(2) Airbus Model A330-243F airplanes, certificated in any category, all manufacturer serial numbers on which Airbus Modification 56966H16199 has been embodied in production or Airbus Service Bulletin A330-28-3105 has been embodied in service.
We are removing Airworthiness Directive (AD) 2010-08-08, which applied to certain Airbus Model A330-243, -341, -342, and -343 airplanes. AD 2010-08-08 required deactivating the water scavenge automatic operation and revising the Limitations section of the airplane flight manual (AFM). We are also removing AD 2011-06-04, which applied to certain Airbus Model A330-243F airplanes. AD 2011-06-04 required revising the Limitations section of the AFM. We issued ADs 2010-08-08 and 2011-06-04 to prevent fuel flow restriction, caused by ice, resulting in a possible engine surge or stall condition, and the engine being unable to provide the commanded thrust. Since we issued AD 2010-08-08 and AD 2011-06-04, we received new data indicating that the water scavenge system (WSS) operation does not induce any risk of fuel feed system (including the engine) blockage by ice on the pipework or pump inlets. We have also determined that the risk of fuel flow restriction by ice at the fuel oil heat exchanger (FOHE) interface on airplanes equipped with Rolls-Royce Trent 700 engines is now addressed by a redesigned FOHE, which incorporates enhanced anti-icing and de- icing performance.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
