Airworthiness Directives; Dassault Aviation Airplanes

We are superseding Airworthiness Directive (AD) 2011-10-01 for all Dassault Aviation Model FALCON 7X airplanes. AD 2011-10-01 required repetitive functional tests of the ram air turbine (RAT) heater, and repair if necessary. This new AD requires revision of the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. This AD was prompted by the need for new and more restrictive maintenance requirements and airworthiness limitations for airplane structures and systems. We are issuing this AD to prevent reduced structural integrity and reduced control of these airplanes due to the failure of system components.
