This final special condition is being issued for the Grob Model G520T Series airplane. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. This novel and unusual design feature includes the use of composite materials for primary flight structure for which the applicable regulations do not contain adequate or appropriate airworthiness standards. This final special condition contains the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that provided by the applicable airworthiness standards.
