Airworthiness Directives; Airbus Airplanes

We propose to supersede airworthiness directives AD 2003-14- 11, AD 2004-11-08, AD 2004-13-25, AD 2004-18-14, AD 2008-06-07, and AD 2012-04-07 that apply to certain Airbus Model A330 and A340 series airplanes. AD 2003-14-11, AD 2004-11-08, AD 2004-13-25, AD 2004-18-14, AD 2008-06-07, and AD 2012-04-07 required revising the maintenance program to incorporate certain maintenance requirements and airworthiness limitations; replacing certain flap rotary actuators; repetitively inspecting elevator servo-controllers and pressure relief valves of the spoiler servo controls (SSCs); repetitively testing the elevator servo control loops, modifying the elevator servo controls, and repetitively replacing certain retraction brackets of the main landing gear; and revising the airplane flight manual. Since we issued those ADs, we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance program to incorporate certain maintenance requirements and airworthiness limitations. The proposed AD also removes Airbus Model A340-200, -300, -500, and -600 series airplanes from the applicability. We are p
