Background

On April 3, 2000, DaimlerChrysler

Aviation, Inc., 7002 Highland Rd.,

Waterford, MI, applied for a

Supplemental Type Certificate (STC) to

modify Gulfstream Aerospace

Corporation G–1159 airplanes. The G–

1159 is a small transport category

airplane. The G–1159 airplanes are

powered by two Rolls Royce Spey RB

(163) 511–8 turbofans with a maximum

takeoff weight of 57,500 pounds. This

aircraft operates with a 2-pilot crew and

can hold up to 19 passengers. The

modification incorporates the

installation of a Honeywell Primus Epic

Control Display System for Retrofit

applications (CDS–R). The CDS–R 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.

Type Certification Basis

Under the provisions of 14 CFR

21.101, DaimlerChrysler Aviation Inc.

must show that the Gulfstream

Aerospace Corporation G–1159

airplanes, as changed, continue to meet

the applicable provisions of the

regulations incorporated by reference

Type Certificate No. A12EA, 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 Gulfstream Aerospace Corporation

G–1159 airplanes include CAR 4b dated

December 31, 1953, including

Amendments 4b–1 thru 4b–14, Special

Regulations SR422B and SR450A, and

Special Conditions in Attachment A of

FAA letter to Grumman dated

September 27, 1965, plus 14 CFR

25.1325 (effective February 1, 1965);

25.175 (effective March 1, 1965) in lieu

of 4b.155(b), plus additional

requirements listed in the type

certificate data sheet that are not

relevant to these special conditions.

If the Administrator finds that the

applicable airworthiness regulations

(i.e., CAR 4b and part 25, as amended)

do not contain adequate or appropriate

safety standards for the Gulfstream

Aerospace Corporation G–1159

airplanes modified by DaimlerChrysler

Aviation Inc. 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 Gulfstream Aerospace

Corporation G–1159 airplanes must

comply with the fuel vent and exhaust

12844 Federal Register / Vol. 66, No. 41 / Thursday, March 1, 2001 / Rules and Regulations

emission requirements of part 34 and

the noise certification requirements of

part 36.

Special conditions, as defined in

§ 11.19, are issued in accordance with

§ 11.38 and become part of the type

certification basis in accordance with

§ 21.101(b)(2).

Special conditions are initially

applicable to the model for which they

are issued. Should DaimlerChrysler

Aviation Inc. 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).

Novel or Unusual Design Features

As noted earlier, the Gulfstream

Aerospace Corporation G–1159

airplanes modified by DaimlerChrysler

Aviation Inc. will incorporate dual

Electronic Primary Flight Display

systems that will perform critical

functions. This system 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.

Discussion

There is no specific regulation that

addresses protection requirements for

electrical and electronic systems from

HIRF. Increased power levels from

ground-based radio transmitters and the

growing use of sensitive avionics/

electronics and electrical systems to

command and control airplanes have

made it necessary to provide adequate

protection.

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

Gulfstream Aerospace Corporation G–

1159 airplanes modified by

DaimlerChrysler Aviation Inc. 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.

High-Intensity Radiated Fields (HIRF)

With the trend toward increased

power levels from ground-based

transmitters, plus the advent of space

and satellite communications coupled

with electronic command and control of

the airplane, the immunity of critical

avionics/electronics and electrical

systems to HIRF must be established.

It is not possible to precisely define

the HIRF to which the airplane will be

exposed in service. There is also

uncertainty concerning the effectiveness

of airframe shielding for HIRF.

Furthermore, coupling of

electromagnetic energy to cockpitinstalled equipment through the cockpit

window apertures is undefined. Based

on surveys and analysis of existing HIRF

emitters, an adequate level of protection

exists when compliance with the HIRF

protection special condition is shown

with either paragraph 1 OR 2 below:

1. A minimum threat of 100 volts rms

per meter electric field strength from 10

KHz to 18 GHz.

a. The threat must be applied to the

system elements and their associated

wiring harnesses without the benefit of

airframe shielding.

b. Demonstration of this level of

protection is established through system

tests and analysis.

2. A threat external to the airframe of

the following field strengths for the

frequency ranges indicated. Both peak

and average field strength components

from the Table are to be demonstrated.

The field strengths are expressed in terms of peak of the root-mean-square (rms) over the complete modulation period.

The threat levels identified above are

the result of an FAA review of existing

studies on the subject of HIRF, in light

of the ongoing work of the

Electromagnetic Effects Harmonization

Working Group of the Aviation

Rulemaking Advisory Committee.

Applicability

As discussed above, these special

conditions are applicable to Gulfstream

Aerospace Corporation G–1159

airplanes modified by DaimlerChrysler

Aviation Inc. Should DaimlerChrysler

Aviation Inc. 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).

Conclusion

This action affects only certain novel

or unusual design features on the

Gulfstream Aerospace Corporation G–

1159 airplanes modified by

Federal Register / Vol. 66, No. 41 / Thursday, March 1, 2001 / Rules and Regulations 12845

DaimlerChrysler Aviation Inc. 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 comments 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.

Controls

AGENCY: Bureau of Export

Administration, Commerce.

ACTION: Final rule.

SUMMARY: This final rule amends the

Export Administration Regulations

(EAR) by removing the additional

license requirements imposed on Serbia

in May 1999. However, a license is

required for all exports and reexports by

U.S. persons of any item subject to the

EAR to persons listed pursuant to

Executive Order 13088, as amended by

Executive Order 13192 of January 17,

2001. The persons subject to sanctions

under amended Executive Order 13088

include Slobodan Milosevic, his family,

his close associates, and those indicted

for war crimes. These sanctioned

persons are identified on the list of

specially designated nationals and

blocked persons maintained by the

Department of the Treasury’s Office of

Foreign Assets Control and identified by

the bracketed suffix initials [FRYM].

Controls are maintained under the EAR

on arms and related materiel to the

Federal Republic of Yugoslavia (Serbia

and Montenegro) consistent with United

Nations Security Council Resolution

1160 of March 3, 1998.

DATES: This rule is effective March 1,

2001.

SUPPLEMENTARY INFORMATION:

Background

Executive Order 13088 of June 9,

1998, as amended by Executive Order

13121 on April 30, 1999, imposed,

among other measures, comprehensive

U.S. export and reexport prohibitions on

the Federal Republic of Yugoslavia

(Serbia and Montenegro). On May 4,

1999, the Bureau of Export

Administration (BXA) issued a final rule

imposing a license requirement for

exports and reexports to Serbia of all

items subject to the EAR and a case-bycase review of applications with a

presumption of denial for other than

humanitarian items. These measures

were intended to deter Serbia’s human

rights offenses against ethnic Albanians

in Kosovo and to prevent the expansion

of the ethnic conflict. BXA’s May 4,

1999 rule did not impose similar

comprehensive controls on exports or

reexports to Montenegro.

Effective January 19, 2001, Executive

Order 13192 amended Executive Order

13088 to revoke previously imposed

prohibitions, including those on exports

and reexports. BXA is taking action

under its export control authorities

consistent with amended Executive

Order 13088. Specifically, this rule

removes the additional license

requirements imposed under the EAR

by the May 4, 1999, rule on exports and

reexports to Serbia, and thus restores

Serbia to the export control status it had

prior to May 4, 1999. However, persons

listed in the Annex to Executive Order

13192, as well as persons designated by

the Secretary of the Treasury, in

consultation with the Secretary of State

pursuant to that order, are subject to

sanctions administered by the

Department of the Treasury’s Office of

Foreign Assets Control. Exports and

reexports of any item subject to the EAR

by a U.S. person to a person designated

pursuant to amended Executive Order

13088 are subject to a license

requirement and a licensing policy of

denial. These sanctioned persons are

included on a list of specially

designated nationals and blocked

persons (SDNs) maintained by the

Department of the Treasury, Office of

Foreign Assets Control (OFAC) and

identified by the bracketed suffix

initials [FRYM]. To obtain additional

information regarding the list of SDNs,

contact OFAC at telephone number 202/

622–2520. BXA provisions regarding

these sanctioned persons are included

in new section 744.16 of the EAR.

This rule eliminates the distinctions

previously applicable to Serbia, Kosovo

and Montenegro, which had been

established by the final rule of

November 5, 1999, for export control

purposes. With the publication of this

rule, Serbia (including the province of

Kosovo) and Montenegro will be listed

together as the Federal Republic of

Yugoslavia (Serbia and Montenegro) for

License Exception eligibility purposes,

as members of ‘‘Country Group B’’ (see

Supplement No. 1 to part 740),
