Vol. 79, No. 35

Friday, February 21, 2014

**DEPARTMENT OF TRANSPORTATION**

**Federal Aviation Administration**

**14 CFR Part 39**

**[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 ofthe 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:

. **SUPPLEMENTARY INFORMATION :** 
Comments Invited

We invite you to send any written 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 comments on the overall regulatory, economic, environmental, and energy 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


### 9869 Federal Register / Vol. 79, No. 35 / Friday, February 21, 2014 / Proposed Rules

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, the FAA proposes to amend 14 CFR part 39 as follows:

**SUPPLEMENTARY INFORMATION :** 
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
