**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2013–01–07, Amendment 39–17321 (78 FR 6725, January 31, 2013), (‘‘AD 2013–01–07’’). AD 2013–01–07 applied to the specified products. The NPRM published in the Federal Register on June 7, 2013 (78 FR 34284). The NPRM proposed to continue to require replacing the HMU at a reduced life. The NPRM also proposed to require inspections of the HMU.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 34284, June 7, 2013).

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for the following editorial changes. We changed paragraphs (e)(1)(iv) and (e)(2)(iv).

Paragraph (e)(1)(iv) now reads, ‘‘Guidance on replacing the complete sleeve and inspecting the complete sleeve female splines, and HP and LP male splines, can be found in Turbomeca Technical Instruction No. 292 73 2847.’’


### 68698 Federal Register / Vol. 78, No. 221 / Friday, November 15, 2013 / Rules and Regulations

Paragraph (e)(2)(iv) now reads, ‘‘Guidance for completing the requirements of paragraph (e)(2) can be found in Turbomeca S.A. Alert Mandatory Service Bulletin (MSB) No. A292 73 2847.’’

We changed paragraph (f) to provide credit for initial replacements specified in paragraph (e) of this AD.

We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (78 FR 32484, June 7, 2013) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 32484, June 7, 2013). Costs of Compliance

We estimate that this AD affects 56 Arriel 2D turboshaft engines installed on helicopters of U.S. registry. We also estimate that it will take about two hours per engine to comply with this AD. The average labor rate is $85 per hour. Required parts cost about $14,400 per engine. Based on these figures, we estimate the total cost of this AD to U.S. operators is $815,920. 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 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 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. List of Subjects in 14 CFR Part 39

**SUPPLEMENTARY INFORMATION :**  History

The FAA published a final rule in the Federal Register establishing Class E airspace at the Battle Mountain VORTAC navigation aid, Battle Mountain, NV (78 FR 58159, September 23, 2013). The FAA received a comment in support of the rule from the NBAA for inclusion in FAA Docket No. FAA– 2013–0530 prior to the closing of the comment period. However, the preamble incorrectly references that there were no comments to the proposal. This action corrects that
statement.

Correction to Final Rule

Accordingly, pursuant to the authority delegated to me, the description under the History heading, as published in the Federal Register on September 23, 2013 (78 FR 58159), Airspace Docket No. 13–AWP–9, FR Doc. 2013–58159, is corrected as follows: On page 58160, column 1, line 2, remove ‘‘No comments were received.’’, and add in their place ‘‘One comment was received from the National Business Aviation Association (NBAA) supporting the establishment of Class E en route airspace.’’.

**IFR Altitudes; Miscellaneous Amendments** 

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

**ACTION :**  Final rule

**SUMMARY :**  This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.

**DATES :**  Effective 0901 UTC, December 12, 2013.

**FOR FURTHER INFORMATION CONTACT :**  Harry Hodges, Flight Procedure Standards Branch (AMCAFS–420), Flight Technologies and Programs Division, Flight Standards Service, Federal Aviation Administration, Mike Monroney Aeronautical Center, 6500 South MacArthur Blvd., Oklahoma City, OK 73169 (Mail Address: P.O. Box 25082 Oklahoma City, OK 73125) telephone: (405) 954–4164.

**SUPPLEMENTARY INFORMATION :**  This amendment to part 95 of the Federal Aviation Regulations (14 CFR part 95) amends, suspends, or revokes IFR altitudes governing the operation of all aircraft in flight over a specified route or any portion of that route, as well as the changeover points (COPs) for Federal airways, jet routes, or direct routes as prescribed in part 95.

The Rule

The specified IFR altitudes, when used in conjunction with the prescribed changeover points for those routes, ensure navigation aid coverage that is adequate for safe flight operations and free of frequency interference. The reasons and circumstances that create the need for this amendment involve matters of flight safety and operational efficiency in the National Airspace System, are related to published aeronautical charts that are essential to the user, and provide for the safe and efficient use of the navigable airspace. In addition, those various reasons or circumstances require making this amendment effective before the next scheduled charting and publication date of the flight information to assure its timely availability to the user. The effective date of this amendment reflects those considerations. In view of the close and immediate relationship between these regulatory changes and safety in air commerce, I find that notice and public procedure before adopting this amendment are impracticable and contrary to the public interest and that good cause exists for making the amendment effective in less than 30 days.

Conclusion

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. It, therefore—(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. For the same reason, the FAA certifies that this amendment will not have a significant economic impact on a substantial
