## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A310-204, -222, -304, -322, and -324 airplanes. This proposed AD was prompted by the manufacturer re-classifying slat extension eccentric bolts as principle structural elements (PSE) with replacement due at or before newly calculated fatigue life limits. This proposed AD would require replacing slat extension eccentric bolts, and associated washers with new slat extension eccentric bolts and washers. We are proposing this AD to prevent fatigue cracking, which could result in the loss of structural integrity of the airplane.
