## Summary

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Airbus airplanes identified above. The original NPRM would have required improving the routing of certain electrical wire bundles in certain airplane zones, as applicable to the airplane model. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This action revises the original NPRM by removing certain requirements, extending the compliance time for a certain replacement, and specifies that the actions in this proposed AD are considered interim action until a terminating action for the removed requirements is approved and available. We are proposing this supplemental NPRM to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
