Airworthiness Directive · Amendment 39-14445 · Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes
Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes
This AD applies to Airbus Model A330-201, -202, -203, -223, -243, -301, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-211, -212, -213, -311, -312, and -313 airplanes; certificated in any category; except airplanes on which Airbus Modification 50650 has been embodied in production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. This AD requires operators to modify the hydraulic control block of the nose landing gear. This AD results from a report of an unexpected steering event (swerve) during the take-off roll of one affected airplane. We are issuing this AD to prevent loss of airplane steering while on the ground, which could result in the airplane going off the side of the runway.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 30 months after the effective date of this AD: Modify the hydraulic control block (HCB) in accordance with the Accomplishment Instructions of the applicable service bulletin in paragraph (f)(1) or (f)(2) of this AD.
(1) For Model A330-200 and A330-300 series airplanes: Airbus Service Bulletin A330-32-3156, dated December 22, 2004.
(2) For Model A340-200 and A340-300 series airplanes: Airbus Service Bulletin A340-32-4194, dated December 22, 2004.
Note 1: The Airbus service bulletins refer to Messier-Bugatti Service Bulletin C24856- 32-064, dated January 26, 2005, as an additional source of service information for doing the modification. At the end of the modification: The HCB part number (P/N) C24856000-9 will become P/N C24856000-11, and the HCB P/N C24856001-7 will become P/N C24856001-9.
After the effective date of this AD, no person may install on any airplane an HCB having P/N C24856000-9 or C24856001-7.
