Airworthiness Directive · Amendment 39-14523 · Airbus Model A318-100 and A319-100 Series Airplanes, A320-111 Airplanes, A320-200 Series Airplanes, and A321-100 and A321-200 Series Airplanes
Airbus Model A318-100 and A319-100 Series Airplanes, A320-111 Airplanes, A320-200 Series Airplanes, and A321-100 and A321-200 Series Airplanes
Superseded. A later AD replaced this one: AD 2013-24-08. Comply with the one in force.
This AD applies to Airbus Model A318-111 and -112 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; A320-111 airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; Model A321-111, -112, and -131 airplanes; and Model A321-211, -212, -213, -231, and -232 airplanes; certificated in any category; except airplanes on which Airbus Modification 27496 has been installed in production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318-100 and A319-100 series airplanes, A320-111 airplanes, A320-200 series airplanes, and A321-100 and A321-200 series airplanes. This AD requires operators to review the airplane's maintenance records to determine the part numbers of the magnetic fuel level indicators (MFLI) of the wing fuel tanks, and related investigative and corrective actions if necessary. This AD results from several in-service incidents of wear and detachment of the top-stops from the MFLI. Such detachment allows the top-stop to move around the wing fuel tank, and the top-stop could come into contact or in close proximity with a gauging probe, resulting in compromise of the air gap between the probe and the structure and creating a potential ignition source. We are issuing this AD to prevent an ignition source in the wing fuel tank in the event of a lightning strike, which could result in a fire or explosion.
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 65 months or 6,500 flight hours after the effective date of this AD, whichever is first: Review the airplane's maintenance records to determine the part number (P/N) of each MFLI of the wing fuel tanks in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-28-1138, dated March 18, 2005. If the P/N cannot be identified, or the P/N is identified in the “old P/N” column of the table in paragraph 1.L., “Interchangeability/Mixability,” of the service bulletin, before further flight, do the applicable related investigative and corrective actions by accomplishing all of the actions in accordance with the Accomplishment Instructions of the service bulletin.
As of the effective date of this AD, no person may install on any airplane any MFLI of the wing fuel tanks with a P/N identified in the “old P/N” column of the table in paragraph 1.L., “Interchangeability/Mixability,” of Airbus Service Bulletin A320-28-1138, dated March 18, 2005.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
