## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Falcon 2000EX airplanes. This AD requires revising the airplane flight manual (AFM) to extend runway length limits for takeoff and landing. This AD also provides for an optional terminating action for the AFM revision. This AD results from an event in which braking efficiency was temporarily lost during landing, but was recovered after the flightcrew fully released and then reapplied the brakes. We are issuing this AD to prevent a runway overrun in the event of loss of braking function, which could result in injury to passengers or flightcrew and damage to the airplane.
