## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 and A300-600 series airplanes. This proposal would require replacement of the rivets that attach the pressurized floor panel to gantries 4 and 5 with new titanium alloy bolts. This proposal also would require, for certain airplanes, repetitive inspections to detect discrepancies of the rivets; and corrective actions, if necessary. 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 prevent failure of the rivets that attach the pressurized floor panel to gantries 4 and 5, which could result in the loss of the floor panel and consequent rapid decompression of the airplane.
