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

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.

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. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. To perform the inspections, use 

paragraph 1.A. or 1.B. of the 

Accomplishment Instructions ‘‘For Engines 

Installed on the Aircraft’’ or 1.A. or 1.B. of 

the Accomplishment Instructions ‘‘For 

Engines Removed from the Aircraft,’’ of Pratt 

& Whitney Service Bulletin PW4G–112–72– 

309, Revision 1, dated July 1, 2010. 

(1) For 15th stage HPC disks that have 

9,865 or fewer cycles since new (CSN) on the 

effective date of this AD, remove the disk 

from service before accumulating 12,000 

CSN. 

(2) For 15th stage HPC disks that have 

accumulated more than 9,865 CSN on the 

effective date of this AD, do one of the 

following: 

(i) Remove the disk from service at the next 

piece-part exposure, not to exceed 2,135 

cycles-in-service (CIS) after the effective date 

of this AD. 

(ii) Perform a borescope inspection (BSI) or 

eddy current inspection (ECI) of the front rail 

of the disk outer rim according to the 

following schedule: 

(A) Within 2,400 cycles-since-last 

fluorescent penetrant inspection or ECI, or 

(B) Within 1,200 cycles-since-last BSI, or 

(C) Before accumulating 12,000 CSN, or 

(D) Within 55 CIS after the effective date 

of this AD, whichever occurs latest. 

(3) If the BSI from paragraph (e)(2)(ii) of 

this AD indicates the presence of a crack in 

the disk outer rim front rail, but you cannot 

visually confirm a crack, perform an ECI 

within 5 CIS after the BSI. 

(4) If you confirm a crack in the front rail 

of the disk outer rim using any inspection 

method, remove the disk from service before 

further flight. 

(f) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

may approve AMOCs for this AD. Use the 

procedures found in 14 CFR 39.19 to make 

your request.

Amendment of Air Traffic Service 

(ATS) Routes in the Vicinity of Vero 

Beach, FL 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; technical 

amendment. 

SUMMARY: This action amends the legal 

descriptions of Jet Routes J–45 and J–79, 

and VHF omnidirectional range (VOR) 


tkelley on DSK3SPTVN1PROD with RULES
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. Cases 

have 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. 

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
