## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD would require modification of the electrical bonding of all structures and systems installed inside the center fuel tank. This proposed AD is prompted by results of fuel system reviews conducted by the manufacturer. We are proposing 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.
