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: 

2011–24–08 Turbomeca S.A.: Amendment 

39–16872; Docket No. FAA–2011–1037; 

Directorate Identifier 2011–NE–30–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective December 7, 2011. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Makila 1A2 turboshaft 

engines, all serial numbers. 

(d) Reason 

(1) This AD results from mandatory 

continuing airworthiness information (MCAI) 

issued by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as: 

A helicopter experienced an inadvertent 

activation of the 65% N1 (gas generator 

speed) back up control mode. 

The subsequent technical investigations 

carried by Turbomeca revealed that an N2 

(power turbine speed) sensor harness wire 

crimping discrepancy was at the origin of 

this event. Further quality investigations 

performed with the supplier led to the 

conclusion that N2 sensor Part Number (P/N) 

0 301 52 001 0 whose Serial Numbers (S/N) 

are between S/N 242 and S/N 339 inclusive 

are potentially concerned by the same 

manufacturing discrepancy. 

This condition, if not corrected, could lead 

to the inadvertent activation of the 65% N1 

back up mode and consequently to 

significant power loss on one or more or both 

engines installed on the same helicopter, 

potentially resulting in an emergency landing 

of the helicopter. 

(2) We are issuing this AD to prevent 

inadvertent activation of the backup control 

mode, which could result in engine power 

loss and emergency landing of the helicopter. 

(e) Actions and Compliance 

(1) Unless already done, do the following 

actions. 

(2) For engines equipped with N2 sensor 

harnesses, P/N 0 301 52 001 0, whose S/Ns 

are between S/N 242 and S/N 339 inclusive, 

do the following: 

(i) If an affected P/N is installed on each 

of the 2 (two) engines of the helicopter, then 

within 10 flight hours (FHs) after the 

effective date of this AD, replace one N2 

sensor harness with an N2 sensor harness 

that is eligible for installation, and within 50 

FHs after the effective date of this AD, 

replace the second harness with an N2 sensor 

harness that is eligible for installation. 

(ii) If an affected P/N is installed only on 

1 (one) engine of the helicopter, then within 

50 FHs after the effective date of this AD, 

replace the affected N2 sensor harness with 

an N2 harness that is eligible for installation. 

(3) After the effective date of this AD, do 

not install in an engine any N2 sensor 

harness, P/N 0 301 52 001 0, whose S/N is 

between S/N 242 and S/N 339 inclusive, 

unless the part has ‘‘SB 0815’’ marked on the 

identification plate. 

(4) After the effective date of this AD, do 

not install in a helicopter an engine equipped 

with an N2 sensor harness, P/N 0 301 52 001 

0, whose S/N is between S/N 242 and S/N 

339 inclusive, unless the part has ‘‘SB 0815’’ 

marked on the identification plate. 

(f) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

FAA, may approve AMOCs for this AD. Use 

the procedures found in 14 CFR 39.19 to 

make your request.

Amendment of VOR Federal Airways 

V–81, V–89, and V–169 in the Vicinity 

of Chadron, NE 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends the legal 

description of the VHF omnidirectional 

range (VOR) Federal airways V–81, V– 

89, and V–169 in the vicinity of 

Chadron, Nebraska. The FAA is taking 

this action because the Chadron VOR 

distance measuring equipment (DME), 

included as part of the V–81, V–89, and 

V–169 route structure, is being renamed 

the Toadstool VOR/DME to avoid 

confusion with Chadron Airport that 

shares the same identifier. 

DATES: Effective Dates: 0901 UTC, April 

5, 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.

Colby Abbott, Airspace, Regulations and

Administration, 800 Independence 

Avenue SW., Washington, DC 20591;

SUPPLEMENTARY INFORMATION: 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

amending the legal description of VOR 

Federal Airways V–81, V–89, and V– 

169, in the vicinity of Chadron, NE. 

Currently, V–81, V–89, and V–169 

include the Chadron, NE, [VOR/DME] as 

part of their route structure. The 

Chadron VOR/DME and the Chadron 

Airport share the same name and 

identifier (CDR), but are located 

nineteen nautical miles apart. A 

navigation facility and airport having 

the same name and identifier causes 

frequent confusion to air traffic 

automation systems, as well as pilot/ 

controller communications. To 

eliminate confusion, and a potential 

flight safety issue, the Chadron VOR/ 

DME is renamed the Toadstool VOR/ 

DME and assigned a new facility 

identifier (TST). All VOR Federal 


erowe on DSK2VPTVN1PROD with RULES
72094 Federal Register / Vol. 76, No. 225 / Tuesday, November 22, 2011 / Rules and Regulations 

airways with Chadron, NE, [VOR/DME] 

included in their legal description are 

amended to reflect the Toadstool, NE, 

[VOR/DME] name change. The name 

change of the VOR/DME will coincide 

with the effective date of this rule. 

Additionally, the exclusionary 

language in the V–169 legal description 

addressing the Devils Lake West 

Military Operations Area (MOA) has 

been simplified for clarity. No changes 

to the current operational use are 

expected to occur from this editorial 

amendment. 

Since this action merely involves 

editorial changes in the legal 

descriptions of VOR Federal airways, 

and does not involve a change in the 

dimensions or operating requirements of 

that airspace, 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 description of four 

VOR Federal Airways in the vicinity of 

Chadron, NE. 

Domestic VOR Federal Airways are 

published in paragraph 6010(a) 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 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: 

Polices 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.
