## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300-600 and A310 series airplanes. This proposal would require modification of the attachment system of the insulation blankets of the forward cargo compartment and related corrective action. This action is necessary to prevent failure of the attachment system of the cargo insulation blankets, which could result in detachment and consequent tearing of the blankets. Such tearing could result in blanket pieces being ingested into and jamming the forward outflow valve of the pressure regulation subsystem, which could lead to cabin depressurization and adversely affect continued safe flight of the airplane. This action is intended to address the identified unsafe condition.
