## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Dassault Model Falcon 900 EX and Mystere-Falcon 900 series airplanes, that would have required installing an attachment support assembly for the fire extinguishing piping in the baggage compartment. This new action revises the proposed rule by proposing to add a requirement to modify the liner panel of the baggage compartment for certain airplanes. The actions specified by this new proposed AD are intended to prevent distortion of the fire extinguishing discharge nozzle as a result of the nozzle not being secure, which could result in poor diffusion of the fire extinguishing agent in the event of a fire in the baggage compartment. This action is intended to address the identified unsafe condition.
