Special Conditions; Piaggio Model P-180 Airplanes

These special conditions are issued to become part of the type certification basis for Piaggio Model P-180 series airplanes. The airplane will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness requirements in Part 23 of the Federal Aviation Regulations (FAR). The novel and unusual design features are associated with the use of advanced composite materials for primary flight structure, the location of the propellers, forward wing (canard) configuration, and an outward opening, main entry door in the pressurized cabin for which the regulations do not contain adequate or appropriate safety standards. These special conditions contain the additional safety standards which the Administrator finds necessary to establish a level of safety equivalent to that envisioned in the applicable regulations.
