## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dassault Model Mystere-Falcon 900 and Falcon 900EX series airplanes. This proposal would require replacement of certain self-adhering soundproofing mats under the passenger consoles in the cabin, which are not sufficiently fire-retardant, with mats that are not self-adhering and are sufficiently fire-retardant. This action is necessary to prevent an uncontrolled fire in the cabin due to self-adhering soundproofing mats under the passenger consoles in the cabin, which are not sufficiently fire-retardant. This action is intended to address the identified unsafe condition.
