Airworthiness Directive · Amendment 39-18546 · Equipment/furnishings
Airbus Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Airbus Model A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes; except airplanes on which Airbus Modification 203672 has been embodied in production.
(2) Airbus Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and all Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of chafing of the feeder cable at the pylon- wing junction due to vibration; one report revealed that the cable loom plastic support bracket of the G-route was broken due to vibration; and another report revealed wire chafing due to clamp damage. This AD requires modifying the cable loom support bracket of the G-route of the inboard pylons at the pylon-wing junction. We are issuing this AD to prevent chafing of the wiring in the pylon-wing area, which could result in an electrical short circuit near a flammable fluid vapor zone, and consequent fire or fuel tank explosion.
Within 18 months after the effective date of this AD: Modify the cable loom support bracket of the G-route 7701VB in the left-hand side of the inboard pylon, and the G-route 7702VB in the right-hand side of the inboard pylon, located at the pylon-wing junction, in accordance with the applicable service information specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD.
