12972 Federal Register / Vol. 75, No. 52 / Thursday, March 18, 2010 / Rules and Regulations 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to International Aero 

Engines (IAE) V2500–A1, V2522–A5, V2524– 

A5, V2525–D5, V2527–A5, V2527E–A5, 

V2527M–A5, V2528–D5, V2530–A5, and 

V2533–A5 turbofan engines with highpressure (HP) compressor stage 3–8 drums, 

part numbers (P/Ns) 6A4900, 6A5467, 

6A6473, 6A7383, 6A7384, 6A7385, and 

6A7401, installed. These engines are 

installed on, but not limited to, Airbus A319, 

A320, and A321 series airplanes and Boeing 

MD–90 airplanes. 

Unsafe Condition 

(d) This AD results from reports of 

fractured vortex reducers found at shop 

visits. We are issuing this AD to inspect for 

cracks in the vortex reducer. Cracks in the 

vortex reducer could result in an 

uncontained failure of the HP compressor 

stage 3–8 drum and subsequent damage to 

the airplane. 

Compliance 

(e) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified unless the 

actions have already been done. 

Onetime Fluorescent Penetrant Inspection 

(f) Fluorescent penetrant inspect the vortex 

reducer for cracks when the HPC stage 3–8 

drum has between 3,000 and 13,500 cyclessince-new (CSN) if all of the following 

conditions also apply: 

(1) The HPC stage 3–8 drum has ever 

operated in an engine at the V2527E–A5, 

V2527M–A5, V2528–D5, V2530–A5, or 

V2533–A5 thrust ratings, 

(2) The vortex reducer had cycles 

accumulated on it when mated with the HPC 

stage 3–8 drum, and 

(3) The HPC stage 3–8 drum had fewer 

than 3,000 CSN when mated to the vortex 

reducer. 

(g) If the vortex reducer is cracked, remove 

both the vortex reducer and the HPC stage 3– 

8 drum from service. 

(h) After the effective date of this AD, do 

not return to service any HPC stage 3–8 drum 

that was removed as specified in paragraph 

(g) of this AD. 

Alternative Methods of Compliance 

(i) The Manager, Engine Certification 

Office, has the authority to approve 

alternative methods of compliance for this 

AD if requested using the procedures found 

in 14 CFR 39.19.

Docket No. 09–ANM–14] 

Amendment of Class E Airspace; 

Rawlins, WY 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action will amend Class 

E airspace at Rawlins, WY, to 

accommodate aircraft using a new Area 

Navigation (RNAV) Global Positioning 

System (GPS) Standard Instrument 

Approach Procedure (SIAP) at Rawlins 

Municipal/Harvey Field. This will 

improve the safety of Instrument Flight 

Rules (IFR) at the airport. 

DATES: Effective Date: 0901 UTC, June 3, 

2010. The Director of the Federal 

Register approves this incorporation by 

reference action under 1 CFR part 51, 

subject to the annual revision of FAA 

Order 7400.9 and publication of 

conforming amendments.

SUPPLEMENTARY INFORMATION: 

History 

On November 9, 2009, the FAA 

published in the Federal Register a 

notice of proposed rulemaking to 

establish additional controlled airspace 

at Rawlins, WY (74 FR 57621). 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. 

Class E airspace designations are 

published in paragraph 6002 and 6005 

of FAA Order 7400.9T signed August 

27, 2009, and effective September 15, 

2009, which is incorporated by 

reference in 14 CFR part 71.1. The Class 

E airspace designations listed in this 

document will be published 

subsequently in that Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

amending the Class E airspace for the 

Rawlins, WY, area adding additional 

controlled airspace extending upward 

from 700 feet above the surface to 

accommodate IFR aircraft executing a 

new RNAV (GPS) approach procedure at 

Rawlins Municipal/Harvey Field, 

Rawlins, WY. This action is necessary 

for the safety and management of IFR 

operations at the airport. 

The FAA has determined 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, 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 FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the U.S. Code. Subtitle 1, 

Section 106 discusses the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the agency’s 

authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it establishes 

additional controlled airspace at 

Rawlins Municipal/Harvey Field, 

Rawlins, WY.
