| 2014-23472 | Airworthiness Directives; Airbus Airplanes | Proposed Rule | We propose to rescind Airworthiness Directive (AD) 2010-08-08, which applies to certain Airbus Model A330-243, -341, -342, and -343 airplanes. AD 2010-08-08 requires deactivating the water scavenge automatic operation and revising the Limitations section of the airplane flight manual (AFM). We also propose to rescind AD 2011-06-04, which applies to certain Model A330-243F airplanes. AD 2011-06-04 requires 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 ADs 2010-08-08 and 2011-06-04, we have determined 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 Trent 700 engines is now addressed by a re-designed FOHE, which incorporates enhanced anti-icing and de-icing performance. | 2014-10-02 | 2014 | 10 | https://www.federalregister.gov/documents/2014/10/02/2014-23472/airworthiness-directives-airbus-airplanes | https://www.govinfo.gov/content/pkg/FR-2014-10-02/pdf/2014-23472.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to rescind Airworthiness Directive (AD) 2010-08-08, which applies to certain Airbus Model A330-243, -341, -342, and -343 airplanes.
