Docket No. NM204
Special Conditions No. 25-194-SC
https://www.federalregister.gov/d/02-247 https://www.federalregister.gov/d/02-247
These special conditions are issued for Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by ElectroSonics. These modified airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of dual Electronic Primary Flight Display systems that perform critical functions. The applicable airworthiness regulations do not contain adequate or appropriate safety 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 that established by the existing airworthiness standards.
Comments on these special conditions may be mailed in duplicate to: Federal Aviation Administration, Transport Airplane Directorate, Attention: Rules Docket (ANM-113), Docket No. NM204, 1601 Lind Avenue SW., Renton, Washington 98055-4056; or delivered in duplicate to the Transport Airplane Directorate at the above address. All comments must be marked: Docket No. NM204. Comments may be inspected in the Rules Docket weekdays, except Federal holidays, between 7:30 a.m. and 4 p.m.
On November 9, 2001, ElectroSonics, 4391 International Gateway, Columbus, Ohio, applied for a Supplemental Type Certificate (STC) to modify Dassault Aviation Model Mystere-Falcon 200, Start Printed Page 48820-C5, 20-D5, 20-E5, and 20-F5 airplanes. The Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 are small transport category airplanes.
The Dassault Aviation Model Mystere-Falcon 200 airplanes are powered by two Garrett Turbine Engine Company ATF3-6A-4C turbine engines with a maximum takeoff weight of 32,000 pounds.
The Dassault Aviation Model Mystere-Falcon 20-C5, 20-D5, 20-E5 and 20-F5 airplanes are powered by two Garrett Engine Division Model TFE-5AR-2C engines with a maximum takeoff weight of 29,000 pounds. These airplanes operate with a 2-pilot crew and can hold up to 10 passengers.
The modification of these airplanes incorporates the installation of a Universal Avionics Electronic Flight Instrument System (EFI-550). The EFI-550 is a replacement for the existing Analog Flight Instrumentation, while also providing additional functional capability and redundancy in the system. The avionics/electronics and electrical systems installed in this airplane have the potential to be vulnerable to high-intensity radiated fields (HIRF) external to the airplane.
Under the provisions of 14 CFR 21.101, ElectroSonics must show that the Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes, as changed, continue to meet the applicable provisions of the regulations incorporated by reference in Type Certificate No. A7EU, 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.” The regulations included in the certification basis for the Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes include Civil Air Regulations 4b, effective December 1953, through Amendment 4b-12; Special Regulation 422B; and 14 CFR part 25, as amended to incorporate Amendments 25-1 through 25-43.
If the Administrator finds that the applicable airworthiness regulations (i.e., part 25, as amended) do not contain adequate or appropriate safety standards for the Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by ElectroSonics, because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16.
In addition to the applicable airworthiness regulations and special conditions, these Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes must comply with the fuel vent and exhaust emission requirements of part 34 and the noise certification requirements of part 36.
Special conditions are initially applicable to the model for which they are issued. Should ElectroSonics apply at a later date for a supplemental type certificate to modify any other model included on the same type certificate to incorporate the same novel or unusual design feature, these special conditions would also apply to the other model under the provisions of § 21.101(a)(1).
As noted earlier, the Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by ElectroSonics will incorporate dual Electronic Primary Flight Display systems that will perform critical functions. These systems may be vulnerable to high-intensity radiated fields external to the airplane. The current airworthiness standards of part 25 do not contain adequate or appropriate safety standards for the protection of this equipment from the adverse effects of HIRF. Accordingly, this system is considered to be a novel or unusual design feature.
To ensure that a level of safety is achieved that is equivalent to that intended by the regulations incorporated by reference, special conditions are needed for the Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by ElectroSonics.
These special conditions require that new avionics/electronics and electrical systems that perform critical functions be designed and installed to preclude component damage and interruption of function due to both the direct and indirect effects of HIRF.

As discussed above, these special conditions are applicable to Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by ElectroSonics. Should ElectroSonics apply at a later date for a supplemental type certificate to modify any other model included on the same type certificate to incorporate the same novel or unusual design feature, these special conditions would apply to that model as well under the provisions of § 21.101(a)(1).
This action affects only certain novel or unusual design features on the Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by ElectroSonics. It is not a rule of general applicability and affects only the applicant who applied to the FAA for approval of these features on the airplane.
Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the supplemental type certification basis for the Dassault Aviation Model Mystere-Falcon 200, 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by ElectroSonics.
Issued in Renton, Washington, on December 27, 2001.
