## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A310-203, -221, and -222 airplanes. This proposed AD was prompted by the manufacturer re-classifying slat extension eccentric bolts as principal structural elements (PSE) with replacement due at or before their calculated fatigue lives. This proposed AD would require replacing certain slat extension eccentric bolts with new bolts. We are proposing this AD to prevent fatigue cracking which could result in the loss of structural integrity of the airplane.
