We propose to supersede Airworthiness Directive (AD) 2014-03- 07, which applies to certain The Boeing Company Model MD-11 and MD-11F airplanes. AD 2014-03-07 requires inspecting certain locations of the wire bundles of the center upper auxiliary fuel tank for damage, and corrective action if necessary. AD 2014-03-07 also requires installing nonmetallic barrier/shield sleeving, new clamps, new attaching hardware, and a new extruded channel. Since we issued AD 2014-03-07, we determined that it is necessary to require an inspection of the wire bundles for damage at additional center upper auxiliary fuel tank locations on certain airplanes. This proposed AD would add that inspection and expand the applicability. We are proposing this AD to address the unsafe condition on these products.
