## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A310-304, -322, -324, and -325 airplanes. This proposed AD was prompted by reports of insufficient clearance between the fuel quantity indicator (FQI) probes and the adjacent structure and metallic components in the wing fuel tanks. This proposed AD would require a one-time detailed visual inspection for sufficient clearance between FQI probes on both the left-hand side and right-hand side of the trim horizontal stabilizer and the adjacent structure and metallic components in the fuel tanks, and modification if necessary. We are proposing this AD to detect and correct insufficient clearance, which could lead to electrical arcing in a fuel tank during a lightning strike, which could result in ignition and consequent fire or explosion in the fuel tank.
