## Summary

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model Mystere-Falcon 50 airplanes. This proposed AD was prompted by a report of an untimely and intermittent indication of slat activity due to chafing of the electrical wiring under the glare shield and behind the flight deck front panel. This proposed AD would require installing two protective plates between the electrical wiring under the glare shield and the engine fire pull handles. We are proposing this AD to prevent chafing of the electrical wiring, which could result in a short circuit and generation of smoke in the cockpit, potential loss of several functions essential for safe flight, and consequent reduced controllability of the airplane.
