## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-200 series airplanes. This proposal would require replacement of certain duct assemblies of the air distribution system for the flight compartment with new duct assemblies with improved insulation, and follow-on actions. This action is necessary to prevent ignition of foam insulation on the air distribution ducts, which could result in a fire in the airplane. This action is intended to address the identified unsafe condition.
