### 56761 Federal Register / Vol. 77, No. 179 / Friday, September 14, 2012 / Rules and Regulations

Federal Register published on April 11, 2000 (65 FR 19477–78). 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 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 this AD:

1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866;

2. Is not a ‘‘significant rule’’ under the 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 regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new AD: 2012–17–04 Rolls-Royce plc: Amendment 39–17167; Docket No. FAA–2012–0848; Directorate Identifier 2012–NE–20–AD.
(a) Effective Date

This airworthiness directive (AD) becomes effective October 1, 2012.
(b) Affected ADs

None. (c) Applicability

This AD applies to Rolls-Royce plc (RR) RB211-Trent 875–17, 877–17, 884–17, 884B– 17, 892–17, 892B–17, and 895–17 turbofan engines that have an intermediate pressure (IP) turbine disc with a serial number listed in Table 1 to paragraph (e) of this AD, installed.
(d) Reason

This AD was prompted by RR performing an evaluation that determined that the current lives for certain IP turbine discs with a steel inclusion may fail before they reach their current mandatory life limits. We are issuing this AD to prevent failure of the IP turbine disc, which could result in uncontained failure of the engine and damage to the airplane. (e) Actions and Compliance

Unless already done, do the following. Remove disc serial numbers (S/Ns) listed in Table 1 to paragraph (e) of this AD within 9,700 standard duty cycles since new.

(f) Installation Prohibition

After the effective date of this AD, do not install any IP and Low Pressure (LP) turbine module on any engine with an IP turbine disc with an S/N listed in Table 1 to paragraph (e) of this AD if the life of the disc is equal to or greater than 9,700 standard duty cycles since new. After the effective date of this AD, do not install any IP turbine disk listed in Table 1 to paragraph (e) of this AD if the life of the disk is equal to or greater than 9,700 standard duty cycles since new. (g) Definitions

For the purposes of this AD, a shop visit is one where the IP and LP turbine module has been removed from the engine. (h) Alternative Methods of Compliance (AMOCs)

The Manager, Engine Certification Office, FAA, may approve AMOCs to this AD. Use the procedures found in 14 CFR 39.19 to make your request.

Airport/Louis Schreiner Field. The geographic coordinates of the airport also are adjusted. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport. Due to subsequent decommissioning, the Shein locator outer marker/nondirectional radio beacon (LOM/NDB) will be removed from the regulatory text.

**DATES :**  Effective date: 0901 UTC, November 15, 2012. 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 May 21, 2012, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to amend Class E airspace for the Kerrville, TX, area, creating additional controlled airspace at Kerrville Municipal Airport/ Louis Schreiner Field (77 FR 29921) Docket No. FAA–2011–1399. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Subsequent to publication, it was discovered that the Shein LOM/NDB had been decommissioned. This action removes the Shein LOM/NDB from the regulatory text,

Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9V dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) Part 71 by amending Class E airspace extending upward from 700 feet above the surface to accommodate new standard instrument approach procedures at Kerrville Municipal Airport/Louis Schreiner Field, Kerrville, TX. This action is necessary for the safety and management of IFR operations at the airport. Geographic coordinates are updated to coincide with the FAA’s aeronautical database. This action also removes the decommissioned Shein LOM/NDB from the regulatory text.

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, 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, describes 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 amends controlled airspace at Kerrville Municipal Airport/Louis Schreiner Field, Kerrville, TX.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures,’’ paragraph 311a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.
