Special Conditions; Dornier Seastar CD-2 Series Airplanes

These special conditions are being issued to become part of the type certification basis for the Claudius Dornier Seastar GmbH and Company Model CD-2 Series amphibian airplanes. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards for normal, utility, acrobatic, and commuter category airplanes. The novel and unusual design features include the use of advanced composite materials for primary flight structure, the location of the engines and propellers, protection from lightning and high energy radio frequency, and emergency flotation equipment 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.
