Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Turbomeca S.A. Arrius 2F turboshaft 

engines with a certain part number oil 

pump installed. This proposed AD was 

prompted by cases of deterioration of 

the gas generator front bearing due to a 

link loss between the pump driver and 

the oil pump shaft. This proposed AD 

would require inspection, and if 

necessary, replacement before further 

flight of the oil pump driver assembly 

and/or the oil pump shaft, or the oil 

pump itself. We are proposing this AD 

to prevent link loss between the pump 

driver and the oil pump shaft, which 

could lead to an engine in-flight 

shutdown, forced landing, and damage 

to the helicopter. 

DATES: We must receive comments on 

this proposed AD by July 20, 2015. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2015– 

0049, dated March 17, 2015 (Corrected 

May 7, 2015) (referred to hereinafter as 

‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

A risk of an in-flight shutdown (IFSD) has 

been identified on an ARRIUS 2F engine, due 

to deterioration of gas generator front bearing. 

This could be the result of lack of lubrication, 

due to a link loss between pump driver and 

oil pump shaft. 

This condition, if not detected and 

corrected, could lead to cases of IFSD, 

possibly resulting in forced landing with 

consequent damage to the helicopter and 

injury to occupants. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

0900. 

Related Service Information Under 1 

CFR Part 51 

Turbomeca S.A. has issued 

Mandatory Service Bulletin (MSB) No. 

319 79 4834, Version B, dated October 

21, 2014. The MSB describes procedures 

for inspecting the oil pump driver 

assembly on the oil pump shaft, the 

pump driver splines, and the oil pump 

splines. This service 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 NPRM. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of France, and is 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing 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 

products of the same type design. This 

proposed AD would require inspection, 

and if necessary, replacement before 

further flight, of the oil pump driver 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 80, No. 98 / Thursday, May 21, 2015 / Proposed Rules 29225 

assembly and/or the oil pump shaft, or 

the oil pump itself. 

Costs of Compliance 

We estimate that this proposed AD 

affects about 96 engines installed on 

helicopters of U.S. registry. We also 

estimate that it would take about two 

hours per product to comply with this 

proposed AD. The average labor rate is 

$85 per hour. Required parts would cost 

about $17,312 per engine. Based on 

these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $1,678,272. 

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 determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the 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.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 airworthiness 

directive (AD): 

Turbomeca S.A.: Docket No. FAA–2015– 

0900; Directorate Identifier 2015–NE– 

12–AD. 

(a) Comments Due Date 

We must receive comments by July 20, 

2015. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Turbomeca S.A. 

Arrius 2F turboshaft engines with oil pump, 

part number (P/N) 0319155050, installed,

Availability and Summary of 

Documents Proposed for Incorporation 

by Reference 

This document proposes to amend 

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 proposed 

rule. FAA Order 7400.9Y lists Class A, 

B, C, D, and E airspace areas, air traffic 

service routes, and reporting points. 

The Proposal 

This action proposes to amend Title 

14, Code of Federal Regulations (14 

CFR), Part 71 by modifying Class E 

airspace extending upward from 700 

feet above the surface to within a 6.4- 

mile radius of Tekamah Municipal 

Airport, Tekamah, NE., reconfiguring 

the airspace for standard instrument 

approach procedures at the airport. The 

Tekamah VOR facility has been 

decommissioned and its associated 

SIAPs have been canceled. Controlled 

airspace is necessary for the safety and 

management of IFR operations for other 

SIAPs at the airport. 

Class E airspace areas are published 

in Paragraph 6005 of FAA Order 

7400.9Y, dated August 6, 2014 and 

effective September 15, 2014, which is 

incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document will be 

published subsequently in the Order. 

The FAA has determined that this 

proposed 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
