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 3–8drum 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.

### 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. List of Subjects in 14 CFR Part 71
