## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dassault Model Mystere-Falcon 50, Mystere-Falcon 900, and Falcon 900EX series airplanes. This proposal would require installing a shield plate over the tank structure above the Stormscope antenna and replacing the Stormscope antenna plug connector with a new connector. This action is necessary to prevent puncture of the fuel tank, in the event of a belly landing, which could result in a post-landing fire if fuel leaking from the tank makes contact with the sparks from the airplane sliding on the ground. This action is intended to address the identified unsafe condition.
