These special conditions are issued to Op Technologies, Inc.; 15236 NW., Greenbrier Parkway, Beaverton, OR 97006 for a Supplemental Type Certificate for the Cirrus Design Corporation Model SR22 airplane. This airplane 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 electronic flight instrument system (EFIS) displays Model Pegasus Primary Flight Displays manufactured by Op Technologies 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).

On September 6, 2006, Op Technologies, Inc.; 15236 NW., Greenbrier Parkway; Beaverton, OR 97006 applied to the FAA for a new Supplemental Type Certificate for the Cirrus Design Corporation Model SR22 airplane. The Model SR22 is currently approved under TC No. A00009CH. The proposed modification incorporates a novel or unusual design feature, such as digital avionics consisting of an EFIS that is vulnerable to HIRF external to the airplane.
Under the provisions of 14 CFR part 21, § 21.101, Op Technologies, Inc. must show that the Cirrus Design Corporation Model SR22 aircraft meets the following provisions, or the applicable regulations in effect on the date of application for the change to the Cirrus Design Corporation Model SR22: Part 23 of the Federal Aviation Regulations effective February 1, 1965, as amended by 23-1 through 23-53, except as follows: § 23.301 through Amendment 47; §§ 23.855, 23.1326, 23.1359, not applicable. 14 CFR part 36 dated December 1, 1969, as amended by current amendment as of the date of type certification. Equivalent Levels of Safety finding (ACE-96-5) made per the Start Printed Page 31445provisions of 14 CFR part 23, § 23.221; Refer to FAA ELOS letter dated June 10, 1998. Equivalent Levels of Safety finding (ACE-00-09) made per the provisions of 14 CFR part 23, §§ 23.1143(g) and 23.1147(b); Refer to FAA ELOS letter dated September 11, 2000, for model SR22. Special Condition (23-ACE-88) for ballistic parachute; 23-134-SC for protection of systems for High Intensity Radiated Fields (HIRF); and 23-163-SC for inflatable restraint system; exemptions, if any; and the special conditions adopted by this rulemaking action.
Op Technologies, Inc. plans to incorporate certain novel and unusual design features into an airplane for which the airworthiness standards do not contain adequate or appropriate safety standards for protection from the effects of HIRF. These features include EFIS, which are susceptible to the HIRF environment, that were not envisaged by the existing regulations for this type of airplane.
As discussed above, these special conditions are applicable to Op Technologies, Inc.; Cirrus Design Corporation Model SR22 airplane. Should Op Technologies, Inc. apply at Start Printed Page 31446a later date for a supplemental type certificate to modify any other model on the same type certificate to incorporate the same novel or unusual design feature, the special conditions would apply to that model 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 Cirrus Design Corporation SR22 airplane modified by Op Technologies, Inc. to add an EFIS.
