Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to all Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-2C, B4-103, and B4-203 series airplanes, that currently requires a one-time inspection of the space between the fuel quantity indication (FQI) probes and any adjacent structures for minimum clearance, and corrective action if necessary. This action would expand the applicability in the existing AD and would require the subject one-time inspection on the additional airplanes. The actions specified by the proposed AD are intended to prevent the possibility of electrical arcing to the fuel tank if the airplane should be struck by lightning. Such arcing could create a potential ignition source within the fuel tank and an increased risk of a fuel tank explosion and fire. This action is intended to address the identified unsafe condition.
