## Abstract

We are adopting a new airworthiness directive (AD) for the products listed above. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires that, as of the effective date of the AD, operation of Model FALCON 7X airplanes is prohibited. This AD was prompted by a report of an uncontrolled pitch trim runaway during descent. We are issuing this AD to prevent loss of control of the airplane.
