Airworthiness Directives; Airbus Model A330 Airplanes, and Model A340-200 and A340-300 Series Airplanes

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.
