## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A320-111 airplanes; and Model A320-200, A321- 100, and A321-200 series airplanes. This proposed AD would require installing a bonding lead between the low pressure valve and the adjacent pipe assembly in each wing. This proposed AD is prompted by the results of fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent an ignition source for fuel vapor in the wing, which could result in fire or explosion in the adjacent wing fuel tank.
