leading edges for discrepancies, in

accordance with Jetstream Service Bulletin

J41–55–002, Revision 1, dated July 25, 1996.

If any discrepancy is found, prior to further

flight, correct the discrepancy in accordance

with the service bulletin.

(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,

International Branch, ANM–116, FAA,

Transport Airplane Directorate. Operators

shall submit their requests through an

appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, International Branch,

Airworthiness Directives; Aerospatiale

Model ATR42 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Aerospatiale Model

ATR42 series airplanes, that requires

removal of certain landing gear

attachment pins, and replacement of the

pins with serviceable pins. This

amendment is prompted by issuance of

mandatory continuing airworthiness

information by a foreign civil

airworthiness authority. The actions

specified by this AD are intended to

prevent wear of the attachment pins,

which could result in collapse of the

main landing gear.

DATES: Effective January 20, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of January 20,

1998.

ADDRESSES: The service information

referenced in this AD may be obtained

from Aerospatiale, 316 Route de

Bayonne, 31060 Toulouse, Cedex 03,

France. This information may be

examined at the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, Rules Docket,

1601 Lind Avenue, SW., Renton,

Washington; or at the Office of the

Federal Register, 800 North Capitol

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 Aerospatiale

Model ATR42 series airplanes was

published in the Federal Register on

August 25, 1997 (62 FR 44915). That

action proposed to require removal of

certain landing gear attachment pins,

and replacement of the pins with

serviceable pins.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. Due

consideration has been given to the

single comment received.

The commenter supports the

proposed rule.

Conclusion

After careful review of the available

data, including the comment noted

above, the FAA has determined that air

safety and the public interest require the

adoption of the rule as proposed.

Cost Impact

The FAA estimates that 88 Model

ATR42 series airplanes of U.S. registry

will be affected by this AD, that it will

take approximately 45 work hours per

airplane to accomplish the required

actions, and that the average labor rate

is $60 per work hour. Required parts

will be provided by the manufacturer at

no cost to operators. Based on these

figures, the cost impact of the AD on

U.S. operators is estimated to be

$237,600, or $2,700 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.
Federal Register / Vol. 62, No. 240 / Monday, December 15, 1997 / Rules and Regulations 65605

Regulatory Impact

The regulations adopted herein will

not have substantial direct effects 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, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

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: This

amendment to 14 CFR part 71 revises

the Class E airspace at Gallup, NM. The

development of a GPS SIAP to RWY 6

at Gallup Municipal Airport, Gallup,

NM has made this action necessary. The

intended effect of this action is to

provide adequate controlled airspace

extending from 700 feet or more above

the surface for Instrument Flight Rules

(IFR) operations at Gallup Municipal

Airport, Gallup, NM.

Class E airspace designations are

published in Paragraph 6005 of FAA

Order 7400.9E, dated September 10,

1997, and effective September 16, 1997,

which is incorporated by reference in 14

CFR § 71.1. The Class E airspace

designation listed in this document will

be published subsequently in the order.

The Direct Final Rule Procedure

The FAA anticipates that this

regulation will not result in adverse or

negative comment and therefore is

issuing it as a direct final rule. A

substantial number of previous

opportunities provided to the public to

comment on substantially identical

actions have resulted in negligible

adverse comments or objections. Unless

a written adverse or negative comment,

or a written notice of intent to submit

an adverse or negative comment is

received within the comment period,

the regulation will become effective on

the date specified above. After the close

of this comment period, the FAA will

publish a document in the Federal

Register indicating that no adverse or

negative comments were received and

confirming the date on which the final

rule will become effective. If the FAA

does receive, within the comment

period, an adverse or negative comment,

or written notice of intent to submit

such a comment, a document

withdrawing the direct final rule will be

published in the Federal Register, and

a notice of proposed rulemaking may be

published with a new comment period.

Comments Invited

Although this action is in the form of

a final rule and was not preceded by a

notice of proposed rulemaking,

comments are invited on this rule.

Interested persons are invited to

comment on this rule by submitting

such written data, views, or arguments

as they may desire. Communications

should identify the Rules Docket

number and be submitted in triplicate to

the address specified under the caption

ADDRESSES. All communications

received on or before the closing date

for comments will be considered, and

this rule may be amended or withdrawn

in light of the comments received.

Factual information that supports the

commenter’s ideas and suggestions is

extremely helpful in evaluating the

effectiveness of this action and

determining whether additional

rulemaking action is needed.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the rule. All comments

submitted will be available, both before
