Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A320-111 airplanes, and Model A320-200 series airplanes. This proposed AD would require installing a bonding strip between each of the two water scavenge jet pumps of the center fuel tank and the rear spar in section 21. 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 center wing fuel tank.
