## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus model airplanes, as specified above. This proposed AD would require modifying the electrical bonding points of additional center tanks. This proposed AD is prompted by the results of fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent electrical arcing inside the fuel tank, due to insufficient bonding, which could result in the ignition of fuel vapors with a potential risk of explosion of the fuel tank.
