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

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.

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, dated 

January 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, dated 

January 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 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Rules and Regulations 32463 

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. 

• 8 work hours plus $2,200 for 

required parts to install an MGB failed 

pump sensor; 

• 4 work hours plus $250 for required 

parts to install MGB vacuum switch 

wiring; 

• 71.7 work hours plus $4,100 for 

required parts to install an MGB oil 

pressure auto bypass system; 

• 1 work hour to activate AMS 7.1; 

and 

• 1 work hour plus $500 for required 

parts to install EGPWS software. 

The total cost of compliance for all 

actions will be about $14,377 per 

helicopter and $632,588 for the U.S. 

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 

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

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 and 

V–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
