Airworthiness Directives; Airbus Airplanes
We are superseding airworthiness directive (AD) 2006-06-14 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. AD 2006-06-14 required operators to review the airplane's maintenance records to determine the part numbers of the magnetic fuel level indicators (MFLIs) of the wing fuel tanks, and perform related investigative and corrective actions if necessary. This new AD also requires an inspection (improved method) to determine the part numbers of the MFLIs, and, if necessary, replacement of the MFLI or repair. This AD was prompted by information that the related investigative actions of AD 2006-06-14 are not fully effective and that an affected MFLI could still be installed on airplanes on which the related investigative actions were accomplished. 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.
