AD FAA-2017-1250

We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X, FALCON 2000EX, and FALCON 900EX airplanes. This AD requires revising the airplane flight manual (AFM) and minimum equipment list (MEL) to incorporate new limitations. This AD also provides an optional terminating action that removes the AFM and MEL limitations. This AD was prompted by a report indicating that, during approach, an airplane had an unexpected change of barometric settings on both the pilot and co-pilot sides, which also impacted certain display and navigational systems. We are issuing this AD to address the unsafe condition on these products.
