Airworthiness Directives; Gulfstream

Model G–1159A (G–III) Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Gulfstream Model

G–1159A (G–III) series airplanes, that

requires modification of the master

caution panel by installing an additional

legend labeled ‘‘BATT ON BUS’’ and

associated wiring to indicate when the

airplane batteries are powering the

direct current (DC) essential bus. This

action is necessary to ensure that the

flight crew is aware that an electrical

system failure has occurred and that the

main airplane batteries are powering the

essential DC bus. If the flight crew is

unaware of this situation, action to stop

the depletion of the airplane batteries

will not be taken and critical

equipment, such as communications

and navigation equipment, could fail.

This action is intended to address the

identified unsafe condition.

DATES: Effective February 14, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of February

14, 2001.

ADDRESSES: The service information

referenced in this AD may be obtained

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to certain Gulfstream

Model G–1159A (G–III) series airplanes

was published in the Federal Register

on October 12, 2000 (65 FR 60593). That

action proposed to require modification

of the master caution panel by installing

an additional legend labeled ‘‘BATT ON

BUS’’ and associated wiring to indicate

when the airplane batteries are

powering the direct current (DC)

essential bus.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

Conclusion

The FAA has determined that air

safety and the public interest require the

adoption of the rule as proposed.

Cost Impact

There are approximately 198

airplanes of the affected design in the

worldwide fleet. The FAA estimates that

144 airplanes of U.S. registry will be

affected by this AD, that it will take

approximately 55 work hours per

airplane to accomplish the required

modification, and that the average labor

rate is $60 per work hour. Required

parts will cost approximately $1,587 per

airplane. Based on these figures, the cost

impact of the AD on U.S. operators is

estimated to be $703,728, or $4,887 per

airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the requirements of this AD action, and

that no operator would accomplish

those actions in the future if this AD

were not adopted. The cost impact

figures discussed in AD rulemaking

actions represent only the time

necessary to perform the specific actions

actually required by the AD. These

figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

The regulations adopted herein will

not have a substantial direct effect on

the States, on the relationship between

the national Government and the States,

or on the distribution of power and

responsibilities among the various

levels of government. Therefore, it is

determined that this final rule does not

have federalism implications under

Executive Order 13132.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant 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)

will not have a significant economic

impact, positive or negative, on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

SUPPLEMENTARY INFORMATION:

History

On September 25, 2000, a proposal to

amend part 71 of the Federal Aviation

Regulations (14 CFR part 71) to establish

the Class E airspace at Indian Mountain,

AK, was published as a Notice of

Proposed Rulemaking (NPRM) in the

Federal Register (65 FR 57573). The

proposal was requested by the U.S. Air

Force to create controlled airspace for

the instrument approach and departure

procedures to RWY 16 and from RWY

34 at Indian Mountain, AK. This action

is necessary in order for the approach

and departure procedures to be

published in the U.S. Government

Flight Information Publication, U.S.

Terminal Procedures—Alaska. This rule

provides adequate controlled airspace

for aircraft flying IFR operations at

Indian Mountain, AK.

Interested parties were invited to

participate in this rulemaking

proceeding by submitting written

comments on the proposal to the

commenters and the FAA. Public

comments to the proposal were

submitted by two pilots from United

States Fish and Wildlife Service

(USFWS), Alaska Aviation Safety

Foundation, Alaska Airmen’s

Association, and Alaska

Communications Systems (ACS) Chief

Pilot. Each expressed concern with the

size of the proposed Class E airspace.

The substance of their concern was that

the proposed Class E airspace was larger

than needed. In addition, Mr. Felix M.

Maguire representing both the Alaska

Airmen’s Association and ACS as their

Chief Pilot expressed concern that the

approach was barely within the

proposed airspace and that the missed

approach was entirely outside the

proposed airspace. The U.S. Air Force

pointed out that the procedures used by

Mr. Maguire to evaluate airspace needs

were not developed by the U.S. Air

Force and therefore have no validity in

correctly analyzing the requested

airspace. The FAA has considered these

comments. The U.S. Air Force, after reevaluation, responded with a revised

request for Class E airspace at Indian

Mountain (PAIM). This request

substantially reduced the size of the

original request and did not include any

additional airspace, outside what was

proposed in the original NPRM. As for

Mr. Maguire’s concern about the

approach procedure being barely within

the proposed airspace and that the

missed approach was entirely outside

the proposed airspace, the FAA concurs.

The additional airspace south of Indian

Mountain (PAIM) needed for missed

approach and departure procedures is

already 1,200 foot Class E airspace and

therefore, is not needed in this

rulemaking. The majority of the revised

requested airspace encompasses the

primary holding assessment area in

accordance with FAA Order 7130.3. The

FAA has determined that the requested

airspace is needed to provide adequate

controlled airspace for aircraft flying

IFR operations at Indian Mountain

LRRS, Alaska. The coordinates for

Indian Mountain LRRS were published

with an error in the latitude coordinates

and is corrected to read as follows: (lat.

65° 59′ 34′′ N., long. 153° 42′ 16′′ W.).

The airspace description does overlap

existing Class E airspace and the

exclusionary verbiage was inadvertently

left out. The following verbiage has been

added to the end of the airspace

description: ‘‘excluding the existing

Class E airspace.’’ Accordingly, as

discussed, since the revised airspace

description is less of a burden to the

public, the rule is adopted with the

incorporated airspace revisions.

The area will be depicted on

aeronautical charts for pilot reference.

The coordinates for this airspace docket

are based on North American Datum 83.

The Class E airspace areas designated as

700/1200 foot transition areas are

published in paragraph 6005 of FAA

Order 7400.9H, Airspace Designations

and Reporting Points, dated September

1, 2000, and effective September 16,

2000, which is incorporated by

reference in 14 CFR 71.1. The Class E

airspace designations listed in this

document will be revised and published

subsequently in the Order.

The Rule

This amendment to 14 CFR part 71

establishes Class E airspace at Indian

Mountain, AK, through a request by the

U.S. Air Force to create controlled

airspace for the instrument approach

and departure procedures to RWY 16

and from RWY 34 at Indian Mountain,

AK. This action is necessary in order for

the approach and departure procedures

to be published in the U.S. Government

Flight Information Publication, U.S.

Terminal Procedures—Alaska. The area

will be depicted on aeronautical charts

for pilot reference. The intended effect

of this rule is to provide adequate

controlled airspace for IFR operations at

Indian Mountain, AK.

The FAA has determined that this

regulation only involves an established

body of technical regulations for which

frequent and routine amendments are

necessary to keep them operationally

current. It, therefore—(1) Is not a

‘‘significant 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 so minimal. Since this is a

routine matter that will only affect air

traffic procedures and air navigation, it

is certified that this rule will not have

a significant economic impact on a
