## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 B4-620, A310-203, A310-221, and A310-222 series airplanes. This proposal would require repetitive inspections of fuselage frame 07 in the upper frame section assemblies of the lateral cockpit windows, and corrective action, if necessary. Accomplishment of certain corrective actions would extend the repetitive inspection interval. This action is necessary to detect and correct fatigue cracking in that area, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
