Airworthiness Directive · Amendment 39-14333 · Airbus Model A320-111 Airplanes; and Model A320-200, A321-100, and A321-200 Series Airplanes
Airbus Model A320-111 Airplanes; and Model A320-200, A321-100, and A321-200 Series Airplanes
This AD applies to Airbus Model A320-111, -211, -212, -214, -231, -232, and -233 airplanes, and Model A321-111, -112, -131, -211, and -231 airplanes, certificated in any category; except those airplanes on which Airbus Modification 23645 has been incorporated in production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A320-111 airplanes; and Model A320-200, A321-100, and A321-200 series airplanes. This AD requires installing a bonding lead between the low pressure valve and the adjacent pipe assembly in each wing. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source for fuel vapor in the wing, which could result in fire or explosion in the adjacent wing fuel tank.
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 56 months after the effective date of this AD, install a bonding lead between the low pressure valve and the adjacent pipe assembly in each wing, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-28-1055, Revision 1, dated March 8, 1994.
Actions accomplished prior to the effective date of this AD in accordance with Airbus Service Bulletin A320-28-1055, dated July 12, 1993, are considered acceptable for compliance with the corresponding actions required by paragraph (f) of this AD.
