SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

for Hiller Model UH–12, UH–12A, UH–

12B, UH–12C, UH–12D, UH–12E, UH–

12E–L, UH–12L, and UH–12L4

helicopters was published in the

Federal Register on August 31, 2000 (65

FR 52958). That action proposed to

require replacing all undrilled-shank

bolts at the pivoting joints in the control

system linkage with drilled-shank bolts

and installing castellated nuts and cotter

pins.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were received on the

proposal or the FAA’s determination of

the cost to the public. The FAA has

determined that air safety and the

public interest require the adoption of

the rule as proposed.

The FAA estimates that 500

helicopters of U.S. registry will be

affected by this AD, that it will take

approximately 24 work hours per

helicopter to accomplish the required

actions, and that the average labor rate

is $60 per work hour. Required parts

will cost approximately $150 per

helicopter. Based on these figures, the

total cost impact of the AD on U.S.

operators is estimated to be $795,000.

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.

Adoption of the Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends part 39 of the

Federal Aviation Regulations (14 CFR

part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding a new airworthiness directive to

read as follows:

2000–24–21 Siam Hiller Holdings, Inc.:

Amendment 39–12028. Docket No.

2000–SW–27–AD.

Applicability: Model UH–12, UH–12A,

UH–12B, UH–12C, UH–12D, UH–12E, UH–

12E–L, UH–12L, UH–12L4 helicopters,

certificated in any category.

Note 1: This AD applies to each helicopter

identified in the preceding applicability

provision, regardless of whether it has been

otherwise modified, altered, or repaired in

the area subject to the requirements of this

AD. For helicopters that have been modified,

altered, or repaired so that the performance

of the requirements of this AD is affected, the

owner/operator must request approval for an

alternative method of compliance in

accordance with paragraph (b) of this AD.

The request should include an assessment of

the effect of the modification, alteration, or

repair on the unsafe condition addressed by

this AD; and if the unsafe condition has not

been eliminated, the request should include

specific proposed actions to address it.

Compliance: Required at the next annual

inspection or within 12 months, whichever

occurs first, unless accomplished previously.

To prevent separation of the control system

attachments at pivoting points and

subsequent loss of control of the helicopter,

accomplish the following:

(a) Replace all undrilled-shank bolts at

pivoting joints in the control system linkage

with drilled-shank bolts, and install

castellated nuts and cotter pins in accordance

with Hiller Aircraft Corporation Service

Bulletin No. 10–4, Revision 2, dated

December 20, 1999.

(b) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager, Los

Angeles Aircraft Certification Office, FAA.

Operators shall submit their requests through

an FAA Principal Maintenance Inspector,

who may concur or comment and then send

it to the Manager, Los Angeles Aircraft

Certification Office.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Los Angeles Aircraft

Certification Office.

(c) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the helicopter

to a location where the requirements of this

AD can be accomplished.

(d) The installation of castellated nuts and

cotter pins shall be done in accordance with

Hiller Aircraft Corporation Service Bulletin

No. 10–4, Revision 2, dated December 20,

1999. This incorporation by reference was

approved by the Director of the Federal

Register in accordance with 5 U.S.C. 552(a)

and 1 CFR part 51. Copies may be obtained

from Hiller Aircraft Corporation, 3200 Imjin

Road, Marina, California 93933–5101,

Revision to the Legal Description of

the Laughlin/Bullhead International

Airport Class D Airspace Area, AZ

AGENCY: Federal Aviation

Administration (FAA) DOT.

Federal Register / Vol. 65, No. 235 / Wednesday, December 6, 2000 / Rules and Regulations 76151

ACTION: Final rule.

SUMMARY: This action revises the legal

description of the Laughlin/Bullhead

International Airport Class D airspace

area, AZ, by including that airspace

within a 4.2-mile radius of the

Laughlin/Bullhead International Airport

west of a line 1.8-miles west of and

parallel to the north/south runway.

EFFECTIVE DATE: January 25, 2001.

SUPPLEMENTARY INFORMATION:

History

The Airspace Branch in the WesternPacific Region received a request from

the Laughlin/Bullhead International

Airport air traffic control tower manager

to include the airspace west of the

airport beyond 1.8 miles of the north/

south runway and within a 4.2 mile

radius of the airport. Class D airspace areas are published

in Paragraph 5000 of FAA Order

7400.9H, Airspace Designations and

Reporting Points, dated September 1,

2000, and effective September 16, 2000,

through September 15, 2001, which is

incorporated by reference in 14 CFR

71.1. The Class D airspace designation

listed in this document will be

published subsequently in the Order.

The Rule

This amendment to 14 CFR part 71 of

the Federal Aviation Regulations revises

the legal description of the Laughlin/

Bullhead International Airport Class D

airspace area, AZ, by including that

airspace within a 4.2-mile radius of the

Laughlin/Bullhead International Airport

west of a line 1.8 miles west of and

parallel to the north/south runway. This

action will change the actual

dimensions, configuration, or operating

requirements of the Laughlin/Bullhead

International Airport Class D airspace

area, AZ.

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. Therefore, this regulation—(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

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.

SUPPLEMENTARY INFORMATION:

Background

On August 31, 2000, the FAA

proposed to amend 14 CFR part 73 to

amend the times of use for Restricted

Areas R–4501A, B, C, D, and E, Fort

Leonard Wood, MO (65 FR 52961).

Interested parties were invited to

participate in this rulemaking

proceeding by submitting written

comments on the proposal to the FAA.

No comments were received. The

Department of Defense in a continuing

need to meet its added national defense

responsibilities has increased its

training requirements of the USA

Reserve and National Guard resources

in many areas of the United States. One

of the locations where this training has

been increased is at Fort Leonard Wood,

MO. This increase in training requires

modification of the times of use for R–

4501 and its subdivisions. Therefore,

the USA has requested that the FAA

amend the times and days of use for R–

4501A, B, C, D, and E. Except for

editorial changes, this amendment is the

same as that proposed in the notice.

Section 73.45 of part 73 was

republished in FAA Order 7400.8H

dated September 1, 2000.

The Rule

This amendment to 14 CFR part 73

modifies the times of use of R–4501 and
