[Docket No. FAA–2006–23809; Directorate 

Identifier 2005–NE–52–AD] 

RIN 2120–AA64 

Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2007–10– 

07, which applies to all Turbomeca S.A. 

Arriel 2B, 2B1, and 2B1A turboshaft 

engines. AD 2007–10–07 currently 

requires an inspection of the splines of 

the coupling assembly and the hydromechanical metering unit (HMU) drive 

gear shaft for wear. This proposed AD 

would require the same inspection and 

expand the affected population. This 

proposed AD would also remove Arriel 

2B1A engines from the applicability. We 

are proposing this AD to prevent failure 

of the HMU drive gear shaft, which 

could lead to damage to the engine and 

damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by April 22, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2006–23809; Directorate Identifier 

2005–NE–52–AD’’ at the beginning of 

your comments. We specifically invite

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

On May 4, 2007, we issued AD 2007– 

10–07, Amendment 39–15048 (72 FR 

26711, May 11, 2007). AD 2007–10–07 

applies to all Turbomeca Arriel S.A. 2B, 

2B1, and 2B1A turboshaft engines. AD 

2007–10–07 requires an initial 

inspection of the splines of the coupling 

assembly and the HMU drive gear shaft 

for wear as well as an additional 

inspection every time the HMU is 

removed. AD 2007–10–07 resulted from 

reports of in-flight shutdown resulting 

from deterioration of the splines of the 

coupling assembly and the HMU drive 

gear shaft. We issued AD 2007–10–07 to 

prevent failure of the HMU drive gear 

shaft, which could lead to damage to the 

engine, and damage to the airplane. 

Actions Since Existing AD Was Issued 

Since we issued AD 2007–10–07, 

Amendment 39–15048 (72 FR 26711, 

May 11, 2007), we received a report of 

HMU drive gear shaft spline wear on 

Turbomeca S.A. Arriel 2 engines. Also, 

since we issued AD 2007–10–07, the 

European Aviation Safety Agency 

issued AD 2013–0170, dated July 30, 

2013. AD 2013–0170 requires inspection 

of the coupling assembly splines and 

the HMU drive gear shaft for wear. AD 

2013–0170 also adds the Arriel 2C, 2C1, 

2C2, 2S1, and 2S2 engines to the list of 

affected engines. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would retain the 

requirements of AD 2007–10–07, 

Amendment 39–15048 (72 FR 26711, 

May 11, 2007) except it would eliminate 

the additional inspection when the 

HMU is compliant after the 500 hour 

inspection and the HMU assembly is 

unchanged. This proposed AD would 

expand the applicability to include 

Turbomeca S.A. Arriel 2C, 2C1, 2C2, 

2S1, and 2S2 engines, while removing 

Arriel 2B1A engines. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 470 engines installed on 

aircraft of U.S. registry. We also estimate 


rmajette on DSK2TPTVN1PROD with PROPOSALS-1
Federal Register / Vol. 79, No. 35 / Friday, February 21, 2014 / Proposed Rules 9869 

that it would take about 2 hours per 

engine to comply with this proposed 

AD. The average labor rate is $85 per 

hour. No parts are required. Based on 

these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $79,900. 

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 

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 that the 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed 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. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator,

I. General Information 

A. Does this action apply to me? 

You may be potentially affected by 

this action if you are an agricultural 

producer, food manufacturer, or 

pesticide manufacturer. The following 

list of North American Industrial 

Classification System (NAICS) codes is 

not intended to be exhaustive, but rather 

provides a guide to help readers 

determine whether this document 

applies to them. Potentially affected 

entities may include: 

• Crop production (NAICS code 111). 

• Animal production (NAICS code 

112). 

• Food manufacturing (NAICS code 

311). 

• Pesticide manufacturing (NAICS 

code 32532). 

If you have any questions regarding 

the applicability of this action to a 

particular entity, consult the person 

listed at the end of the pesticide petition 

summary of interest. 

B. What should I consider as I prepare 

my comments for EPA? 

1. Submitting CBI. Do not submit this 

information to EPA through 

regulations.gov or email. Clearly mark 

the part or all of the information that 

you claim to be CBI. For CBI 

information in a disk or CD–ROM that 

you mail to EPA, mark the outside of the 

disk or CD–ROM as CBI and then 

identify electronically within the disk or 

CD–ROM the specific information that 

is claimed as CBI. In addition to one 

complete version of the comment that 

includes information claimed as CBI, a 

copy of the comment that does not 

contain the information claimed as CBI 

must be submitted for inclusion in the 

public docket. Information so marked 

will not be disclosed except in 

accordance with procedures set forth in 

40 CFR part 2. 

2. Tips for preparing your comments. 

When submitting comments, remember 

to: 

i. Identify the document by docket ID 

number and other identifying 

information (subject heading, Federal 

Register date and page number). 

ii. Follow directions. The Agency may 

ask you to respond to specific questions 

or organize comments by referencing a 

Code of Federal Regulations (CFR) part 

or section number. 

iii. Explain why you agree or disagree; 

suggest alternatives and substitute 

language for your requested changes. 

iv. Describe any assumptions and 

provide any technical information and/ 

or data that you used. 

v. If you estimate potential costs or 

burdens, explain how you arrived at 

your estimate in sufficient detail to 

allow for it to be reproduced. 

vi. Provide specific examples to 

illustrate your concerns and suggest 

alternatives. 

vii. Explain your views as clearly as 

possible, avoiding the use of profanity 

or personal threats. 

viii. Make sure to submit your 

comments by the comment period 

deadline identified. 

3. Environmental justice. EPA seeks to 

achieve environmental justice, the fair 

treatment and meaningful involvement 

of any group, including minority and/or 

low-income populations, in the 

development, implementation, and 

enforcement of environmental laws, 

regulations, and policies. To help 

address potential environmental justice 

issues, the Agency seeks information on 

any groups or segments of the 

population who, as a result of their 

location, cultural practices, or other 

factors, may have atypical or 

disproportionately high and adverse 

human health impacts or environmental 

effects from exposure to the pesticides 

discussed in this document, compared 

to the general population. 

II. What action is the Agency taking? 

EPA is announcing its receipt of 

several pesticide petitions filed under 

section 408 of the Federal Food, Drug, 

and Cosmetic Act (FFDCA), (21 U.S.C. 

346a), requesting the establishment or 

modification of regulations in 40 CFR 

part 180 for residues of pesticide 

chemicals in or on various food 

commodities. The Agency is taking 

public comment on the requests before 

responding to the petitioners. EPA is not 

proposing any particular action at this 

time. EPA has determined that the
