## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A330 and A340 series airplanes. This proposal would require repetitive inspections to detect cracking of the fuselage skin in the area of the VHF2 antenna, repair, if necessary. This proposal also would provide for optional terminating action for the repetitive inspections. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to detect and correct such cracking, which could result in cabin depressurization of the airplane.
