## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318-100, A319-100, A320-200, A321-100, and A321- 200 series airplanes; and Model A320-111 airplanes. This AD requires modification of the electrical bonding of all structures and systems installed inside the center fuel tank. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent electrical arcing in the center fuel tank due to inadequate bonding, which could result in an explosion of the center fuel tank and consequent loss of the airplane.
