Special Conditions; Chelton Flight Systems, Inc.; Various Airplane Models; Protection of Systems for High Intensity Radiated Fields (HIRF)
The effective date of these special conditions is August 21, 2002. Comments must be received on or before September 30, 2002.
67 FR 55699
Docket No. CE187, Special Condition 23-127-SC
02-22117
https://www.federalregister.gov/d/02-22117 https://www.federalregister.gov/d/02-22117
These special conditions are issued to Chelton Flight Systems, Inc., 1109 Main Street, Suite 560, Boise, ID 83702, for a Supplemental Type Certificate for the models listed under the heading “Type Certification Basis.” This special condition includes various airplane models to streamline the certification process as recommended from completed Safer Sky Programs. The primary objective of streamlining the certification process is to improve the safety of the airplane fleet by fostering the incorporation of both new technologies that can be certificated affordably under 14 CFR part 23.
The 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 electronic flight instrument system (EFIS) display Model EFIS II manufactured by Chelton Flight Systems, Inc., 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.
Comments may be mailed in duplicate to: Federal Aviation Administration, Regional Counsel, ACE-7, Attention: Rules Docket Clerk, Docket No. CE187, Room 506, 901 Locust, Kansas City, Missouri 64106. All comments must be marked: Docket No. CE187. Comments may be inspected in the Rules Docket weekdays, except Federal holidays, between 7:30 a.m. and 4 p.m.
Interested persons are invited to submit such written data, views, or arguments as they may desire. Communications should identify the regulatory docket or notice number and be submitted in duplicate to the address specified above. All communications received on or before the closing date for comments will be considered by the Administrator. The special conditions Start Printed Page 55700may be changed in light of the comments received. All comments received will be available in the Rules Docket for examination by interested persons, both before and after the closing date for comments. A report summarizing each substantive public contact with FAA personnel concerning this rulemaking will be filed in the docket. Commenters wishing the FAA to acknowledge receipt of their comments submitted in response to this notice must include a self-addressed, stamped postcard on which the following statement is made: “Comments to Docket No. CE187.” The postcard will be date stamped and returned to the commenter.
On April 25, 2002, Chelton Flight Systems, Inc., 1109 Main Street, Suite 560, Boise, ID 83702, made an application to the FAA for a new Supplemental Type Certificate for airplane models listed under the type certification basis. The models are currently approved under the type certification basis listed in the paragraph headed “Type Certification Basis.” 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, Chelton Flight Systems, Inc., must show that affected airplane models, as changed, continue to meet the applicable provisions, of the regulations incorporated by reference in Type Certificate Numbers listed below or the applicable regulations in effect on the date of application for the change. The regulations incorporated by reference in the type certificate are commonly referred to as the original “type certification basis” and can be found in the Type Certificate Numbers listed below. In addition, the type certification basis of airplane models that embody this modification will include § 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.

Recent advances in technology have given rise to the application in aircraft designs of advanced electrical and electronic systems that perform functions required for continued safe flight and landing. Due to the use of sensitive solid state advanced components in analog and digital electronics circuits, these advanced systems are readily responsive to the transient effects of induced electrical current and voltage caused by the HIRF. The HIRF can degrade electronic systems performance by damaging components or upsetting system functions. Start Printed Page 55702
2. For the purpose of these special conditions, the following definition applies: Critical Functions: Functions whose failure would contribute to, or Start Printed Page 55703cause, a failure condition that would prevent the continued safe flight and landing of the airplane.
