Airbus Airplanes
Superseded. A later AD replaced this one: AD 2016-08-14. Comply with the one in force.
This AD applies to the Airbus airplanes, certificated in any category, specified in paragraphs (c)(1) and (c)(2) of this AD, all manufacturer serial numbers.
(1) Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes.
(2) Airbus Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 and -300 series airplanes, and Model A340-200, - 300, -500, and -600 series airplanes. This AD was prompted by results from fuel system reviews conducted by the airplane manufacturer. This AD requires removing bulb-type maintenance lights; installing a drain mast on certain airplanes; and installing muffs on connecting bleed elements on certain airplanes. We are issuing this AD to prevent ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss 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.
Except airplanes on which Airbus Modification 56739 has been incorporated in production: Within 26 months after the effective date of this AD, remove the maintenance lights, in accordance with the Accomplishment Instructions of the applicable Airbus service information specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD.
