AD FAA-2019-0253

The FAA is superseding Airworthiness Directive (AD) 2016-07- 22, which applied to all Airbus SAS Model A300 B4-600, B4-600R, and F4- 600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. AD 2016-07-22 required modifying the electrical routing installation at the right-hand (RH) and left-hand (LH) wings to achieve a minimum distance between wiring bundles and surrounding structures. This new AD retains the requirements of AD 2016-07-22 and, for certain airplanes, adds a requirement to further modify the electrical installations in both wings, as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by reports of missing installation information for certain airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
