and the axial crack dimension ‘‘A’’ is less

than 0.8 inches long, in accordance with any

one of the SBs cited in paragraph (a) of this

AD.

crack dimension ‘‘A’’ is equal to or greater

than 0.8 inches but less than or equal to 1.0

inch, in accordance with any one of the SBs

cited in paragraph (a) of this AD.

(C) Remove from service prior to further

locations described in the above SB, through

reviewing maintenance records. If

maintenance records cannot be located, or

maintenance records indicate that a weld

repair with no stress relief or a weld repair

with a local stress relief that has been

performed at any of the 10 boss locations or

2 mount pad locations, perform furnace

remove web material at any boss locations

prior to the effective date of this AD in

accordance with the original issue of PW SB

No. JT9D–7R4–72–469, dated October 2,

1992, accomplish the following:

(1) Unless maintenance records indicate

that x-ray inspections were performed at the

last shop visit where diffuser case repairs

were accomplished at the 10 boss locations,

prior to the effective date of this AD, in

accordance with PW JT9D–7R4 Engine

Manual, Section 72–41–02, Repair–28,

Any person may obtain a copy of this

Notice of Proposed Rulemaking (NPRM)

by submitting a request to the Federal

Aviation Administration, Manager,

Airspace Branch, ASO–520, Air Traffic

Georgia 30320. Communications must

NPRM. Persons interested in being

Advisory Circular No. 11–2A which

describes the application procedure.

The Proposal

The FAA is considering an

amendment to part 71 of the Federal

Aviation Regulations (14 CFR part 71) to

amend the Class E airspace area at New

Bern, NC. The required weather

observation information is available on

a continuous basis to the air traffic

control facility providing service to New

Bern, Craven County, NC, Airport.

Therefore, the Class E surface area

airspace at New Bern, NC, meets the

requirement for modification from part

time to continuous. Class E airspace

areas designated as a surface area for an

airport 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 designations listed in this

document would be published

subsequently in the Order.

The FAA has determined that this

proposed 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,

when promulgated, will not have a

significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.

The Proposed Amendment

In consideration of the foregoing, the

Federal Aviation Administration

proposes to amend 14 CFR part 71 as
