Summary
We propose to supersede Airworthiness Directive (AD) 96-25-04, which applies to certain Airbus SAS Model A320 series airplanes. AD 96- 25-04 requires repetitive inspections to detect chafing of the wire looms (bundles) in the wing and the horizontal stabilizer and in certain areas of the main landing gear (MLG) bays; repair or replacement, protection, and realignment, if necessary; installation of protective sleeves around the wire bundles; and realignment of bundles that are not guided centrally into the conduit end fittings. Since we issued AD 96-25-04, investigations identified issues with the previously installed protective sleeves. This proposed AD would partially retain the requirements of AD 96-25-04 and would require modification of the wing electrical installation, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
