Federal Register / Vol. 72, No. 212 / Friday, November 2, 2007 / Rules and Regulations 62107 

value using laboratory tests, in 

paragraph 2, as follows: 

(1) The applicant may demonstrate 

that the operation and operational 

capability of the installed electrical and 

electronic systems that perform critical 

functions are not adversely affected 

when the aircraft is exposed to the HIRF 

environment defined below: 

Frequency 

Field strength 

(volts per meter) 

Peak Average 

10 kHz–100 kHz ....... 50 50 

100 kHz–500 kHz ..... 50 50 

500 kHz–2 MHz ........ 50 50 

2 MHz–30 MHz ......... 100 100 

30 MHz–70 MHz ....... 50 50 

70 MHz–100 MHz ..... 50 50 

100 MHz–200 MHz ... 100 100 

200 MHz–400 MHz ... 100 100 

400 MHz–700 MHz ... 700 50 

700 MHz–1 GHz ....... 700 100 

1 GHz–2 GHz ........... 2000 200 

2 GHz–4 GHz ........... 3000 200 

4 GHz–6 GHz ........... 3000 200 

6 GHz–8 GHz ........... 1000 200 

8 GHz–12 GHz ......... 3000 300 

12 GHz–18 GHz ....... 2000 200 

18 GHz–40 GHz ....... 600 200 

The field strengths are expressed in terms 

of peak root-mean-square (rms) values. 

or, 

(2) The applicant may demonstrate by 

a system test and analysis that the 

electrical and electronic systems that 

perform critical functions can withstand 

a minimum threat of 100 volts per meter 

(RMS), electrical field strength, from 10 

kHz to 18 GHz. When using this test to 

show compliance with the HIRF 

requirements, no credit is given for 

signal attenuation due to installation. 

A preliminary hazard analysis must 

be performed by the applicant, for 

approval by the FAA, to identify either 

electrical or electronic systems that 

perform critical functions. The term 

‘‘critical’’ means those functions whose 

failure would contribute to, or cause, a 

failure condition that would prevent the 

continued safe flight and landing of the 

airplane. The systems identified by the 

hazard analysis that perform critical 

functions are candidates for the 

application of HIRF requirements. A 

system may perform both critical and 

non-critical functions. Primary 

electronic flight display systems, and 

their associated components, perform 

critical functions such as attitude, 

altitude, and airspeed indication. The 

HIRF requirements apply only to critical 

functions. 

Compliance with HIRF requirements 

may be demonstrated by tests, analysis, 

models, similarity with existing 

systems, or any combination of these. 

Service experience alone is not 

acceptable since normal flight 

operations may not include an exposure 

to the HIRF environment. Reliance on a 

system with similar design features for 

redundancy as a means of protection 

against the effects of external HIRF is 

generally insufficient since all elements 

of a redundant system are likely to be 

exposed to the fields concurrently. 

Applicability 

As discussed above, these special 

conditions are applicable to the Model 

208B, Garmin G1000 project. Should 

Cessna Aircraft Company apply at a 

later date for an amended or 

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. 

Conclusion 

This action affects only certain novel 

or unusual design features on one model 

of airplane. 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. 

The substance of these special 

conditions has been subjected to the 

notice and comment period in several 

prior instances and has been derived 

without substantive change from those 

previously issued. It is unlikely that 

prior public comment would result in a 

significant change from the substance 

contained herein. For this reason, and 

because a delay would significantly 

affect the certification of the airplane, 

which is imminent, the FAA has 

determined that prior public notice and 

comment are unnecessary and 

impracticable, and good cause exists for 

adopting these special conditions upon 

issuance. The FAA is requesting 

comments to allow interested persons to 

submit views that may not have been 

submitted in response to the prior 

opportunities for comment described 

above.

special conditions is as follows: 

Authority: 49 U.S.C. 106(g), 40113 and

11.38 and 11.19. 

The Special Conditions 

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 Model 208B, 

Garmin G1000 project airplane modified 

by Cessna Aircraft Company to add an 

EFIS. 

1. Protection of Electrical and 

Electronic Systems from High Intensity 

Radiated Fields (HIRF). Each system 

that performs critical functions must be 

designed and installed to ensure that the 

operations, and operational capabilities 

of these systems to perform critical 

functions, are not adversely affected 

when the airplane is exposed to high 

intensity radiated electromagnetic fields 

external to the airplane. 

2. For the purpose of these special 

conditions, the following definition 

applies: Critical Functions: Functions 

whose failure would contribute to, or 

cause, a failure condition that would 

prevent the continued safe flight and 

landing of the airplane.

SUPPLEMENTARY INFORMATION: 

History 

On Wednesday, August 15, 2007, the 

FAA proposed to amend part 71 of the 

Federal Aviation Regulations (14 CFR 

part 71) to establish Class D airspace at 

Independence Municipal Airport, KS 

(72 FR 45699). The proposal was to 

establish a Class D airspace area to 

provide controlled airspace for flight 

operations due to the establishment of 

an air traffic control tower. Interested 

parties were invited to participate in 

this rulemaking proceeding by 

submitting written comments on the 

proposal to the FAA. No comments 

objecting to the proposal were received. 

The Rule 

This notice amends part 71 of the 

Federal Aviation Regulations (14 CFR 

part 71) by establishing a Class D 

airspace area extending upward from 

the surface to an including 3,300 feet 

above sea level within a 4.6-mile radius 

of Independence Municipal Airport, KS. 

The establishment of an air traffic 

control tower has made this action 

necessary. The intended effect of this 

action is to provide controlled airspace 

for flight operations at Independence 

Municipal Airport, KS. The area will be 

depicted on appropriate aeronautical 

charts. 

Class D airspace areas extending 

upward from the surface of the earth are 

published in Paragraph 5000 of FAA 

Order 7400.9R, Airspace Designations 

and Reporting Points, signed August 15, 

2007, and effective September 15, 2007, 

which is incorporated by reference in 14 

CFR 71.1. of the same Order. The Class 

D airspace designation listed in this 

document will be published 

subsequently in the Order. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequently and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation—(1) 

is not a ‘‘significantly regulatory action’’

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

Regulatory Evaluation as the anticipated 

impact is to minimal. Since this is a 

routine matter than will only affect air 

traffic procedures and air navigation, it 

is certified that this rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

This rulemaking is promulgated 

under the authority described in 

Subtitle VII, Part A, Subpart I, Section 

40103. Under that section, the FAA is 

charged with prescribing regulations to 

assign the use of the airspace necessary 

to ensure the safety of aircraft and the 

efficient use of airspace. This regulation 

is within the scope of that authority 

since it contains flight operations at 

Independence Municipal Airport, KS.
