Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A319 and A320 series airplanes. This proposal would require modifying the electrical bonding of the fuel return line in each wing between ribs 7 and 8. This action is necessary to reduce the potential for electrical arcing within the fuel tank due to insufficient electrical bonding, which could result in a fire or explosion in the fuel tank. This action is intended to address the identified unsafe condition.
