AD FAA-2015-0825

We are superseding Airworthiness Directive (AD) 2015-02-04 for certain Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2015- 02-04 required installing two protective plates between the electrical wiring under the glare shield and the engine fire pull handles. This new AD continues to require installing two protective plates between the electrical wiring under the glare shield and the engine fire pull handles. This AD was prompted by our determination that the published version of AD 2015-02-04 incorrectly identified the AD number as "AD 2014-02-04" in a certain paragraph. We are issuing 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.
