These special conditions are issued to Quest Aircraft Company, LLC; 1200 Turbine Drive; Sandpoint, ID 83864 for a type certificate for the Kodiak Model 100 airplane. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of electrical and electronic systems that perform critical functions for which the applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of these systems from the effects of high intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.

On March 6, 2000, Quest Aircraft Company, LLC; 1200 Turbine Drive; Sandpoint, ID 83864 applied to the FAA for a type certificate for the Kodiak Model 100. Changes in technology have given rise to advanced airplane electrical and electronic systems and higher energy levels from high-power radio frequency transmitters such as radio and television broadcast stations, radar and satellite uplink transmitters. The combined effect of these developments has been an increased susceptibility of electrical and electronic systems to electromagnetic fields. The proposed modification incorporates a novel or unusual design feature, such as electrical and electronic systems, that are vulnerable to HIRF external to the airplane.
Under the provisions of 14 CFR part 21, § 21.17, Quest Aircraft Company must show that the Kodiak Model 100 airplane meets the type certification basis for the airplane, as applicable, and § 23.1301 of Amendment 23-20; §§ 23.1309, 23.1311, and 23.1321 of Amendment 23-49; and § 23.1322 of Amendment 23-43; exemptions, if any; and the special conditions adopted by this rulemaking action.
Special conditions, as appropriate, as defined in § 11.19, are issued in accordance with § 11.38 after public notice and become part of the type certification basis in accordance with § 21.17.
Special conditions are initially applicable to the model for which they are issued. Should the applicant apply for a supplemental type certificate to modify any other model already included on the same type certificate to Start Printed Page 5916incorporate the same novel or unusual design feature, the special conditions would also apply to the other model under the provisions of § 21.101.
Quest Aircraft Company plans to incorporate certain novel and unusual design features into the Kodiak Model 100 airplanes for which the airworthiness standards do not contain adequate or appropriate safety standards for protection from the effects of HIRF. These features include electrical and electronic systems that perform critical functions, which are susceptible to the HIRF environment, that were not envisaged by the existing regulations for this type of airplane.
Furthermore, the HIRF environment has undergone a transformation that was not foreseen when the current requirements were developed. Higher energy levels are radiated from transmitters that are used for radar, radio, and television. Also, the number of transmitters has increased significantly. There is uncertainty concerning the effectiveness of airframe shielding for HIRF. Furthermore, coupling to cockpit-installed equipment through the cockpit window apertures is undefined.
As discussed above, these special conditions are applicable to the Quest Aircraft Company, LLC Kodiak Model 100. Should Quest Aircraft Company, LLC apply at a later date for a supplemental type certificate for a type design change that incorporates the same novel or unusual design feature, the special conditions would apply to that change as well under the provisions of § 21.101.

Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the type certification basis for the Quest Aircraft Company Kodiak Model 100.
