**SUPPLEMENTARY INFORMATION :** 

Discussion

On July 26, 2012, at 77 FR 43738, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 to include an AD that would apply to Eurocopter Model EC130 B4 helicopters with a cabin vibration damper installed, except those modified in accordance with Modification 073565. That NPRM proposed to require installing a vibration damper casing assembly on both sides of the helicopter. The proposed requirements were intended to prevent contact with the flight controls in the event of a cabin vibration blade failure, jamming of a flight control, and subsequent loss of control of the helicopter.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, issued EASA AD No. 2006–0278, dated September 7, 2006 (AD 2006– 0278), to correct an unsafe condition for the Eurocopter Model EC130 B4 helicopter. EASA advises of a cracked cabin vibration damper blade, which could lead to jamming of a flight control.

Comments

We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (77 FR 43738, July 26, 2012).

FAA’s Determination

This helicopter has been approved by the aviation authority of France and is approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of this same type design and that air safety and the public interest require adopting the AD requirements as proposed.

Differences Between This AD and the EASA AD

The EASA AD requires two daily visual inspections for cracks in the blade of each cabin vibration damper and replacement of a blade if there is a crack; this AD does not. The EASA AD requires compliance by a calendar date. This AD requires compliance within 100 hours time-in-service.

Related Service Information

Eurocopter has issued Alert Service Bulletin (ASB) No. 53A008, Revision 0, dated July 19, 2006 (ASB 53A008), which supersedes ASB No. 05A002, Revision 0, dated July 18, 2006, and specifies installing a cabin vibration damper containment device. EASA classified ASB 53A008 as mandatory and issued AD 2006–0278 to ensure the


### 18231 Federal Register / Vol. 78, No. 58 / Tuesday, March 26, 2013 / Rules and Regulations

continued airworthiness of these helicopters. Costs of Compliance

We estimate that this AD will affect 122 helicopters of U.S. Registry.

We estimate that operators may incur the following costs in order to comply with this AD.

• $340 for 4 work-hours to install a vibration damper casing assembly at an average labor rate of $85 per work-hour,

• $1,500 for required parts per helicopter, and

• $224,480 total cost for the fleet. 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 helicopters identified in this rulemaking action. Regulatory Findings

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 to the extent that it justifies making a regulatory distinction; 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.

We prepared an economic 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

**Amendment of VOR Federal Airway V– 233, Springfield, IL** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule, technical amendment.

**SUMMARY :**  This action amends VHF Omnidirectional Range (VOR) Federal Airway V–233 in the vicinity of Springfield, IL. The FAA is taking this action to correct the V–233 description contained in Part 71 to ensure it matches the information contained in the FAA’s aeronautical database, matches the depiction on the associated charts, and ensures the safety and efficiency of the National Airspace System (NAS).

**DATES :**  Effective date 0901 UTC March 26, 2013. 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

After a recent review of aeronautical data, the Aeronautical Navigation Products Group identified the VOR Federal airway V–233 description did not match the airway information contained in the FAA’s aeronautical database or the charted depiction of the airway. When V–233 was amended in the Federal Register of August 8, 2005 (70 FR 45527), the airway was realigned to reflect a radial change due to the relocation of the Spinner VHF Omnidirectional Range Tactical Air Navigation (VORTAC) navigation aid. However, the final rule erroneously used the magnetic radial information from the Spinner VORTAC to describe the fix between the Spinner VORTAC and the Roberts VOR/Distance Measuring Equipment (VOR/DME) navigation aids instead of the true radial information that should have been used. The FAA aeronautical database contains the correct radial information for describing the airway fix between the Spinner VORTAC and Roberts VOR/ DME in the airway description and the associated aeronautical charts remain published correctly. To overcome any confusion or flight safety issues associated with conflicting airway description information being published, the FAA is amending the V– 233 legal description to reflect the correct Spinner VORTAC radial information.

The Rule

The FAA amends Title 14 Code of Federal Regulations (14 CFR) part 71 by amending the legal description of VOR Federal airway V–233 in the vicinity of Springfield, IL. Specifically, the FAA amends V–233 to reflect the true radial information from the Spinner VORTAC (061 ° radial) to describe the fix between the Spinner VORTAC and Roberts VOR/ DME navigation aids; thus, matching the information currently contained in the FAA’s aeronautical database and the charted depiction of the airway.

VOR Federal airways are listed in paragraph 6010 of FAA Order 7400.9W dated August 8, 2012, and effective September 15, 2012, which is incorporated by reference in 14 CFR 71.1. The VOR Federal airway listed in this document will be revised subsequently in the Order.

Accordingly, since this is an administrative correction to update the V–233 description to be in concert with the FAA’s aeronautical database and charting, notice and public procedures under Title 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 Department of Transportation (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 amends an existing VOR Federal airway within the NAS.

Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with 311a, FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures.’’ 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.
