97–25–13 British Aerospace Regional

Aircraft [Formerly Jetstream Aircraft

Limited, British Aerospace (Commercial

Aircraft) Limited]: Amendment 39–

10237. Docket 97–NM–104–AD.

Applicability: BAe Model ATP airplanes

having constructor’s numbers 2002 through

2063 inclusive; and all Model HS 748 series

airplanes; certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes 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 as indicated, unless

accomplished previously.

To detect and correct corrosion of the

cylinder tube of the main hydraulic

accumulator, which could result in loss of

certain hydraulic system functions that are

essential for safe operation of the airplane,

accomplish the following:

(a) Within 30 days after the effective date

of this AD, perform an inspection of the main

hydraulic accumulator for corrosion, in

accordance with British Aerospace Service

Bulletin ATP–29–15, or HS748–29–49, both

dated February 25, 1997; as applicable. If any

discrepancy is found, prior to further flight,

accomplish the applicable corrective actions

specified in the service bulletins.

(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,

ANM–116.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the International Branch,

ANM–116.

(c) Special flight permits may be issued in

accordance with §§ 21.197 and 21.199 of the

Federal Aviation Regulations (14 CFR 21.197

and 21.199) to operate the airplane to a

location where the requirements of this AD

can be accomplished.

(d) The actions shall be done in accordance

with British Aerospace Service Bulletin

ATP–29–15, dated February 25, 1997, and

British Aerospace Service Bulletin HS748–

29–49, dated February 25, 1997. This

Revision to Chicago Midway Airport

Class C Airspace Area; Illinois

AGENCY: Federal Aviation

Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: This action amends the legal

description of the Chicago Midway

Airport Class C airspace area. Currently,

the legal description uses the Runway

31L localizer course to define the

southeast boundary of Chicago

Midway’s Class C airspace outer ring

(that area between 5 and 10 nautical

miles [NM]). Since the legal description

was published, the Chicago Midway

Airport added another runway to the

outside of Runway 31L, making the old

Runway 31L the new Runway 31C. To

keep the Class C airspace area

boundaries unchanged, a correction to

the legal description must be made. This

action will make the necessary

correction by changing ‘‘Chicago

Midway 31L localizer course’’ to read

‘‘Chicago Midway 31C localizer course.’’

EFFECTIVE DATE: 0901 UTC, February 26,

1998.

SUPPLEMENTARY INFORMATION:

The Rule

This action amends 14 CFR part 71 by

changing the legal description of the

Chicago Midway Airport Class C

airspace area. Currently, the legal

description uses the Runway 31L

localizer course to define the southeast

boundary of the Chicago Midway Class

C airspace outer ring (that area between

5 and 10 NM). Since the description was

published, Chicago Midway Airport

added another runway to the outside of

Runway 31L, making the old Runway

31L the new Runway 31C. To keep the

Class C airspace area boundaries

unchanged, a correction to the legal

description must be made. This action

will make the necessary correction by

changing ‘‘Chicago Midway 31L

localizer course’’ to read ‘‘Chicago

Midway 31C localizer course.’’

Since this action merely involves

changes in the legal description of the

Chicago Midway Class C airspace area

and does not involve a change in the

dimensions or operating requirements of

that airspace, notice and public

procedure under 5 U.S.C. 553(b) are

unnecessary.

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.
Federal Register / Vol. 62, No. 237 / Wednesday, December 10, 1997 / Rules and Regulations 65013

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,

when promulgated, will not have a

significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.

Class C airspace areas are published

in paragraph 4000 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 C airspace area listed in

this document will be published

subsequently in the Order.

[Airspace Docket No. 97–AGL–41]

Modification of the Legal Description

of Class E Airspace; Hancock, MI

AGENCY: Federal Aviation

Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: This action modifies the legal

description of Class E airspace at

Hancock, MI. The current legal

description indicates less than

continuous times of operation for the

Class E airspace for Houghton County

Memorial Airport. Actual times of

operation for the airspace are

continuous. The legal description must

reflect the actual times of operation.

This action will accurately reflect the

actual times of operation for the Class E

airspace at Hancock, MI.

SUPPLEMENTARY INFORMATION:

History

On Thursday, September 11, 1997, the

FAA proposed to amend 14 CFR part 71

to modify the legal description of the

Class E airspace at Hancock, MI (62 FR

47777). The proposal was to change the

legal description to accurately reflect

the existing continuous times of

operation for the airspace.

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. Class E airspace

designated as a surface area are

published in paragraph 6002 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 Rule

This amendment to 14 CFR part 71

modifies the legal description of the

Class E airspace at Hancock, MI, by

removing the statement which indicates

less than continuous times of operation

for the airspace. The actual times of

operation for the Class E airspace at

Hancock, MI, are continuous.

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.
