Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede airworthiness directive (AD) 2006-06- 14, that applies to 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 requires 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 related investigative and corrective actions if necessary. Since we issued AD 2006-06-14, we received information that the related investigative actions of the existing AD are not fully effective and that an affected MFLI could still be installed on airplanes on which the related investigative actions were accomplished. This proposed AD would also require an inspection (improved method) to determine the part numbers of the MFLIs, and, if necessary, replacement of the MFLI or repair. We are proposing 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.
