Airbus Model A330 Airplanes, and Model A340-200 and A340-300 Series Airplanes
This AD applies to all Airbus Model A330 airplanes, and Model A340-200 and A340-300 series airplanes; certificated in any category; except those airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD.
(1) Airplanes on which Airbus Modification 53446 has been incorporated in production.
(2) Model A330 airplanes on which Airbus Mandatory Service Bulletin A330-25-3249, Revision 01, dated July 10, 2007, has been embodied in service.
(3) Model A340-200 and -300 series airplanes on which Airbus Mandatory Service Bulletin A340-25-4245, Revision 01, dated July 10, 2007, has been embodied in service.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A330, A340-200, and A340- 300 series airplanes. That AD currently requires repetitive inspections of a certain bracket that attaches the flight deck instrument panel to the airplane structure; related investigative and corrective actions if necessary; and replacement of the existing bracket with a titanium- reinforced bracket, which ends the repetitive inspections in the existing AD. This new AD adds requirements only for airplanes on which the existing bracket was replaced with a titanium-reinforced bracket in accordance with the existing AD. The additional requirement is a one- time inspection to determine if certain fasteners are broken or cracked, and corrective actions if necessary. This AD results from a report that incorrect torque values could damage the bracket. We are issuing this AD to prevent a cracked bracket. Failure of this bracket, combined with failure of the horizontal beam, could result in collapse of the left part of the flight deck instrument panel, and consequent reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable time specified in paragraph (f)(1) or (f)(2) of this AD, perform a detailed inspection of the bracket having part number (P/N) F2511012920000, which attaches the flight deck instrument panel to the airplane structure, in accordance with Airbus Mandatory Service Bulletin A330-25-3227 or A340-25-4230, both Revision 01, both dated May 3, 2005, as applicable.
(1) For Model A330 series airplanes: Prior to the accumulation of 16,500 total flight cycles, or within 60 days after April 25, 2005 (the effective date of AD 2005-06-08, amendment 39-14016, which was superseded by AD 2006-26-12), whichever is later.
(2) For Model A340-200 and -300 series airplanes: Prior to the accumulation of 9,700 total flight cycles, or within 2,700 flight cycles after April 25, 2005, whichever is later.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
If no crack is found during the initial inspection required by paragraph (f) of this AD: Repeat the inspection thereafter at the applicable interval specified in paragraph (g)(1) or (g)(2) of this AD, in accordance with Airbus Mandatory Service Bulletin A330-25-3227 or A340-25-4230, both Revision 01, both dated May 3, 2005, as applicable, until the replacement specified in paragraph (j) of this AD has been accomplished.
(1) For Model A330 series airplanes: Intervals not to exceed 13,800 flight cycles.
(2) For Model A340-200 and -300 series airplanes: Intervals not to exceed 7,000 flight cycles.
If any crack is found during any inspection required by paragraph (f) or (g) of this AD: Do the actions in paragraphs (h)(1) and (h)(2) of this AD, except as provided by paragraph (i) of this AD, in accordance with Airbus Mandatory Service Bulletin A330-25-3227 or A340-25-4230, both Revision 01, both dated May 3, 2005, as applicable, until accomplishment of the replacement required by paragraph (j) of this AD.
(1) Before further flight: Replace the cracked bracket with a new, improved bracket having P/N F2511012920095, in accordance with Airbus Mandatory Service Bulletin A330-25-3227 or A340-25-4230, both Revision 01, both dated May 3, 2005, as applicable.
(2) Repeat the inspection of the replaced bracket as required by paragraph (f) of this AD, at the time specified in paragraph (h)(2)(i) or (h)(2)(ii) of this AD. Then, do repetitive inspections or replace the bracket as specified in paragraph (g) or (h) of this AD, as applicable.
(i) For Model A330 series airplanes: Within 16,500 flight cycles after replacing the bracket.
(ii) For Model A340-200 and -300 series airplanes: Within 9,700 flight cycles after replacing the bracket.
(i) If both flanges of a bracket are found broken during any inspection required by this AD: Before further flight, replace the bracket as specified in paragraph (h) of this AD and perform any applicable related investigative and corrective actions (which may include inspections for damage to surrounding structure caused by the broken bracket, and corrective actions for any damage that is found), in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA) (or its delegated agent).
Except as required by paragraph (h)(1) of this AD: Within 72 months after February 8, 2007 (the effective date of AD 2006-26-12), replace existing brackets having P/N F2511012920000 or P/N F2511012920095 with titanium-reinforced brackets having P/N F2511305220096; and perform any related investigative and corrective actions (which may include detailed inspections for cracking of the bracket or damage to surrounding structure caused by a broken bracket, and applicable corrective actions for any damage that is found); in accordance with Airbus Service Bulletin A330-25-3249 or A340-25-4245, both dated May 3, 2005; or Airbus Mandatory Service Bulletin A330-25-3249 or A340-25-4245, both Revision 01, both dated July 10, 2007; as applicable.
