V2530–A5, and V2533–A5 Turbofan 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for IAE 

V2500–A1, V2522–A5, V2524–A5, 

V2525–D5, V2527–A5, V2527E–A5, 

V2527M–A5, V2528–D5, V2530–A5, 

and V2533–A5 turbofan engines. This 

AD requires a onetime fluorescent 

penetrant inspection of certain vortex 

reducers for cracks. 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 high-pressure (HP) compressor stage 

3–8 drum and subsequent damage to the 

airplane. 

DATES: This AD becomes effective April 

22, 2010. 

ADDRESSES: The Docket Operations 

office is located at Docket Management 

Facility, U.S. Department of 

Transportation, 1200 New Jersey 

Avenue, SE., West Building Ground 

Floor, Room W12–140, Washington, DC

(781) 238–7117; fax (781) 238–7199. 

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD. The proposed AD 

applies to IAE V2500–A1, V2522–A5, 

V2524–A5, V2525–D5, V2527–A5, 

V2527E–A5, V2527M–A5, V2528–D5, 

V2530–A5, and V2533–A5 turbofan 

engines. We published the proposed AD 

in the Federal Register on April 30, 

2009 (74 FR 19904), and a supplemental 

proposed AD on December 23, 2009 (74 

FR 68192). That action proposed to 

require a onetime inspection of certain 

vortex reducers for cracks, and replacing 

the reducer and HP compressor stage 3– 

8 drum if the reducer is cracked. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. We responded to the comments 

received on the NPRM, in the 

supplemental NPRM. We received no 

comments on the supplemental NPRM 

or on the determination of the cost to 

the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed. 

Costs of Compliance 

We estimate that this AD will affect 

six IAE turbofan engines installed on 

airplanes of U.S. registry. We also 

estimate that it will take about one 

work-hour per engine to perform the 

actions, and that the average labor rate 

is $80 per work-hour. No parts are 

required. Based on these figures, we 

estimate the total cost of the AD to U.S. 

operators to be $480. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

Section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701, 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We have determined that this AD will 

not have federalism implications under 

Executive Order 13132. This AD 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. 

For the reasons discussed above, I 

certify that this AD: 

(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. 

We prepared a summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary at the address listed 

under ADDRESSES.

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.

telephone (425) 203–4537. 

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.
