### 32461 Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Rules and Regulations

Costs of Compliance

We estimate that this AD will affect 16 helicopters of U.S. Registry.

We estimate that operators may incur the following costs in order to comply with this AD. We estimate a minimal cost to change the life limit of the ring gear. If required, we estimate it would take 27.5 hours to replace a ring gear carrier assembly at $85 per work hour. Required parts would cost $7,591 for a total of $9,929 per helicopter. 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

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

**SUPPLEMENTARY INFORMATION :** 

Discussion

On July 23, 2014, at 79 FR 42719, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Sikorsky Model S–92A helicopters. The NPRM proposed to require inserting an RFM Supplement into the applicable RFM, and depending on the helicopter’s serial number, installing an MGB failed pump sensor and vacuum switch wiring, installing an MGB oil auto bypass system, activating AMS 7.1 software to show a new MGB ‘‘OIL OUT’’ visual warning, and updating the EGPWS software to include an aural annunciation of a complete oil pressure loss condition.

The proposed AD was prompted by one accident and one in-service oil leakage incident where it was discovered during subsequent investigations that the pilot failed to activate the bypass valve within 5 seconds of the oil pressure dropping below 35 psi, as required by the RFM. Both accident and incident investigations found that the pilot activated the bypass valve well beyond the 5 seconds. The manual operation of the bypass valve within 5 seconds of the oil pressure dropping below 35 psi has proven not to be a realistic expectation. The proposed requirements were intended to alert and prevent MGB oil loss, which could lead to failure of the MGB and subsequent loss of control of the helicopter.

Comments

Sikorsky commented that it supported issuing the AD but felt portions of the ‘‘Discussion’’ section in the preamble of the NPRM (79 FR 42719, July 23, 2014) needed clarification.

We agree with some of the commenter’s language regarding the function of the MGB oil auto bypass system. However, the commenter has not requested that we change the proposed rule.

FAA’s Determination

We have reviewed the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of the same type design and that air safety and the public interest require adopting the AD requirements as proposed.

Related Service Information Under 1 CFR Part 51

We reviewed Sikorsky S–92A Rotorcraft Flight Manual (RFM) Supplement No. 45, Part I, dated July 30, 2012. The RFM supplement provides preflight checks and emergency procedures for the oil pump failure indicating system and the MGB auto bypass. This information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the

**ADDRESSES** section of this AD.

Other Related Service Information

Sikorsky has issued the following service information:

• Alert Service Bulletin (ASB) No. 92–63–024C, Revision C, dated October 7, 2011, for certain serial-numbered helicopters specifies installing a main module input gear box switch assembly and modifying the MGB vacuum switch wiring. Before making the modification, the ASB states an AMS 4.1 or greater version must first be installed and the following Customer Service Notices (CSN) completed: CSN 92–068C, Revision C, dated March 27, 2012, and CSN 92–069A, Revision A, dated November 10, 2011.

• ASB 92–63–027, Basic Issue, datedJanuary 21, 2013, for certain serialnumbered helicopters specifies installing an MGB oil pressure automatic bypass system, activating an MGB ‘‘OIL OUT’’ visual warning in the AMS 7.1 software, and performing systems operational checkout procedures. Before or when installing the MGB oil pressure auto bypass system, the ASB states the following must be complied with: CSN 92–089, Basic Issue, dated January 10, 2013; ASB 92–34–002, Basic Issue, dated January 21, 2013; and ASB 92–63–024C, Revision C, dated October 7, 2011.

• ASB 92–34–002, Basic Issue, datedJanuary 21, 2013, for certain serialnumbered helicopters with certain partnumbered EGPWS installed, specifies installing EGPWS updated software version 030, which adds an MGB ‘‘OIL OUT’’ aural warning, in accordance with Honeywell International, Inc., Service Bulletin 965–1595–34–23, Revision 0, dated March 13, 2012. Before or during installation of the updated software, the ASB states the following must be complied with: ASB 92–63–027, Basic Issue, dated January 21, 2013, and CSN 92–089, Basic Issue, dated January 10, 2013.

Differences Between This AD and the Service Information

This AD requires compliance within 500 hours time-in-service, and the service information specifies certain dates and calendar times. Costs of Compliance

We estimate that this AD will affect 44 helicopters of U.S. Registry.

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


### 32463 Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Rules and Regulations

at $85 per hour. The work hours and required parts costs are estimated as follows:

• .5 work hour to insert the RFM Supplement into the RFM.

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

**ACTION :**  Final rule.

**SUMMARY :**  This action amends VOR Federal Airways V–31, V–36, V–98, V– 164 and V–252 by removing from the route descriptions, those segments that extend into and/or through Canadian airspace. This action is necessary to match route changes made by Canada as part of the Windsor-Toronto-Montreal (W–T–M) project. The route segments in Canada are no longer in effect; therefore, the United States has issued Notices to Airmen (NOTAM) identifying the affected segments as ‘‘not authorized’’ pending the deletion of the segments from the route descriptions through this rulemaking action.

**DATES :**  Effective date: 0901 UTC, August 20, 2015. 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 :**  Authority for This Rulemaking

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 is merely an editorial change to the legal descriptions of V–31, V–36, V–98, V–164 and V–252 to reflect changes in the Canadian route
structure. Background

This action amends VOR Federal airways V–31, V–36, V–98, V–164 andV–252 as a result of the WindsorToronto-Montreal (W–T–M) and Northeast United States Cross-border Airspace Modernization and Redesign initiative. NavCanada, in an effort to transition to an Area Navigation (RNAV) route system, removed a number of conventional airways, many of which crossed the United States/Canadian border. The airways listed above with the exception of V–98 were part of that initiative that became effective on November 13, 2014 (79 FR 57758). Canadian segments of V–98 were subsequently removed by Canada in January 2015. Coordination for the modification of the Federal airways listed above was not completed in time for inclusion in the November 13, 2014, docket action. Currently, the United States has issued regulatory Notices to Airman (NOTAM) classifying the segments of the above listed airways lying within Canadian airspace as ‘‘not authorized.’’

This action is required to match the changes in the Canadian route structure. It will enhance safety within the National Airspace System and will facilitate a seamless air traffic route system between the two countries. Availability and Summary of Documents for Incorporation by Reference

This document amends FAA Order 7400.9Y, Airspace Designations and Reporting Points, dated August 6, 2014, and effective September 15, 2014. FAA Order 7400.9Y is publicly available as listed in the **ADDRESSES** section of this final rule. FAA Order 7400.9Y lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by removing those former route segments in Canadian airspace from the descriptions of VOR Federal airways V– 31, V–36, V–98, V–164 and V–252. This action aligns the United States airways with route changes instituted by Canada as part of NavCanada’s W–T–M project.

The following is a summary of the specific changes by route. Where new navigation aid radials are designated, both True and Magnetic degrees are stated. Otherwise, only True degrees are shown.

V–31 The segment between the intersection of the Rochester 279 ° and the Toronto, Canada 150 ° radials is removed and a new end point formed by the intersection of the Rochester 279 ° and the Buffalo, NY 023 ° (T)/031 ° (M) radials is inserted.

V–36 The segments between Thunder Bay, ON, Canada and the intersection of the Toronto and Buffalo radials is removed, The amended route extends between Buffalo, NY and the intersection of the LaGuardia, NY 310 ° and the Stillwater, NJ 043 ° radials as currently published.

V–98 The segments between Windsor, ON, Canada and St. Jean, PQ, Canada are removed.

V–164 The segment between Toronto, ON, Canada and Buffalo, NY is removed. The amended route extends
