Special Conditions: Dassault Aviation Model Falcon 7X Airplane, Windshield Coating in Lieu of Wipers

This special condition is issued for the Dassault Aviation Model Falcon 7X airplane. This airplane will have a novel or unusual design feature associated with use of a hydrophobic windshield coating, rather than windshield wipers, as the means to maintain a clear portion of the windshield during precipitation conditions, as required by the airworthiness standards for transport category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. This special condition contains the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
