## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dassault Model Falcon 2000 and 900EX, and Dassault Model Mystere-Falcon 900 series airplanes. This proposal would require measuring the paint thickness on the upper and lower surfaces of the left and right sides of the horizontal stabilizer, performing corrective actions if necessary, and installing maintenance caution placards on the upper surface of the left and right sides of the horizontal stabilizer. This action is necessary to prevent structural damage to the horizontal stabilizer after a direct lightning strike, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
