## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dassault Model Mystere-Falcon 50 series airplanes. This proposal would require applying PR (fuel tank sealant) and installing PR patches over the internal side panel recesses of the left-hand and right-hand feeder tanks at certain frames and stringers. This action is necessary to prevent fuel ignition in the event of a lightning strike and consequent uncontained rupture of the fuel tank(s). This action is intended to address the identified unsafe condition.
