### 42425 Federal Register / Vol. 77, No. 139 / Thursday, July 19, 2012 / Rules and Regulations

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),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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. 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 removing airworthiness directive (AD) 2011–14–07, Amendment 39–16742 (76 FR 47056, August 4, 2011), and adding the following new AD: 2012–13–02 Pratt & Whitney Division: Amendment 39–17104; Docket No. FAA–2010–1095; Directorate Identifier 2009–NE–40–AD.
(a) Effective Date

This AD is effective August 23, 2012.
(b) Affected ADs

This AD supersedes AD 2011–14–07, Amendment 39–16742 (76 FR 47056, August 4, 2011).
(c) Applicability

This AD applies to Pratt & Whitney Division PW4074 and PW4077 turbofan engines with 15th stage high-pressure compressor (HPC) disks, part number (P/N) 55H615, installed.
(d) Unsafe Condition

This AD results from multiple shop findings of cracked 15th stage HPC disks. We are issuing this AD to prevent cracks from propagating into the disk bolt holes, which could result in a failure of the 15th stage HPC disk, uncontained engine failure, and damage to the airplane.

### 42426 Federal Register / Vol. 77, No. 139 / Thursday, July 19, 2012 / Rules and Regulations

Federal airways V–3, V–51, V–159, V– 225, V–295 and V–537, in the vicinity of Vero Beach, FL. The FAA is taking this action because the name of the Vero Beach, FL, VOR Tactical Air Navigation (VORTAC) facility, which is included in the descriptions of the above routes, is being changed to the Treasure VORTAC.

**DATES :**  Effective Dates: 0901 UTC, September 20, 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.

**FOR FURTHER INFORMATION CONTACT :**  Paul Gallant, Airspace, Regulations and ATC Procedures Group, Office of Airspace Services, Federal Aviation Administration, 800 Independence Avenue SW., Washington, DC 20591; telephone: (202) 267–8783.

**SUPPLEMENTARY INFORMATION :**  Background

Vero Beach Municipal Airport, FL, is located 4.1 NM southwest of the Vero Beach VORTAC. The airport and the VORTAC have the same name and three-letter identifier (VRB) which has caused some safety concerns. Caseshave recently been observed where GPSequipped aircraft have navigated via the VRB Airport rather than the VRB VORTAC as intended. To preclude this in the future, the name of the VORTAC is being changed to Treasure VORTAC with the new three-letter identifier ‘‘TRV.’’

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by amending the legal descriptions of Jet Routes J–45 and J–79; and VOR Federal Airways V–3, V–51, V–159, V–225, V– 295 and V–537, to reflect the name change of one of the navigation aids used to define the routes. To eliminate confusion, and potential flight safety issues, the Vero Beach VORTAC is renamed the Treasure VORTAC and is assigned a new three-letter identifier (TRV). The VORTAC name change does not alter the current alignment of the affected routes.

Additionally, in the J–45 description, the words ‘‘Virginia Key’’ are inserted between the words ‘‘Virginia Key, FL,’’ and ‘‘INT 014 ° ’’ to indicate that the 014 ° radial is referenced from the Virginia Key VOR/DME. The description of V–3 is amended by inserting the word ‘‘Quebec’’ before the words ‘‘PQ, Canada.’’ In V–51, the ‘‘Pahokee 009 ° ’’ radial is changed to the ‘‘Pahokee 010° ’’ radial. J–45, V–3 and V51 are all currently charted correctly and these changes simply correct unintended omissions from the descriptions of J–45 and V–3, and a one degree radial error in V–51.

Since this action merely involves editorial changes in the legal descriptions of the above ATS routes, and does not involve a change in the dimensions or operating requirements of the affected routes, I find that notice and public procedures under 5 U.S.C. 553(b)
are unnecessary.

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 United States Code. 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.

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 the 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 revises the legal descriptions of jet routes and airways in the vicinity of Vero Beach, FL to eliminate confusion.

Jet Routes are published in paragraph 2004; and Domestic VOR Federal Airways are published in paragraph 6010(a), respectively, 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 domestic Jet Routes and VOR Federal Airways listed in this document will be published subsequently in the Order.

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 consists of editorial changes only and is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.

**SUPPLEMENTARY INFORMATION :** 
The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by removing reference to the Grinnell NDB from the legal description of Grinnell Regional Airport, Grinnell, IA, and amends the geographic coordinates of the airport to coincide with the FAA’s aeronautical database. The Grinnell NDB has been decommissioned and is not needed as part of the airspace description. This is an administrative change and does not affect the boundaries, altitudes, or operating requirements of the airspace, therefore, notice and public procedures under 5 U.S.C. 553(b) are unnecessary.

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.
