## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-600, 737-700, 737-700C, 737-800, and 737-900 series airplanes, that requires, for certain airplanes, installation of screws and spacers to secure the wire bundles for the aft fuel boost pumps of the main fuel tanks. For certain other airplanes, this amendment requires a general visual inspection of the wire bundles to determine if the wire bundles are clamped, and/or if they are damaged; further investigation, as applicable; repair of any damage; and installation of applicable brackets, clamps, and spacers to secure the wire bundles. This action is necessary to prevent electrical arcing in a fuel leakage zone, which could result in an uncontrolled fire. This action is intended to address the identified unsafe condition.
