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 all 

Turbomeca S.A. Arriel 1A1, 1A2, 1B, 

1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, 

and 1S1 turboshaft engines. This 

proposed AD was prompted by several 

reports of uncommanded in-flight 

shutdown (IFSD) on Arriel 1 engines. 

This proposed AD would require 

performing a high gas generator speed 

(NG) rating vibration check. We are 

proposing this AD to prevent an 

uncommanded in-flight shut-down of 

the engine, which could result in an 

emergency landing. 

DATES: We must receive comments on 

this proposed AD by November 13, 

2012. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov and follow 

the instructions for sending your 

comments electronically. 

• Mail: Docket Management Facility, 

U.S. Department of Transportation, 1200 

New Jersey Avenue SE., West Building 

Ground Floor, Room W12–140, 

Washington, DC 20590–0001. 

• Hand Delivery: Deliver to Mail 

address above between 9 a.m. and 5 

p.m., Monday through Friday, except 

Federal holidays. 

• Fax: (202) 493–2251. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this proposed AD, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Operations 

office (phone: (800) 647–5527) is the 

same as the Mail address provided in 

the ADDRESSES section. Comments will 

be available in the AD docket shortly 

after receipt.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0117, 

dated July 3, 2012 (referred to after this 

as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Several cases of uncommanded in-flight 

shut-down (IFSD) have been reported on 

ARRIEL 1 engines. Results of subsequent 

investigations showed that some Gas 

Generator (GG) rear bearing failures have 

occurred following ‘‘Level 3’’ maintenance 

operations on the GG Assembly. Some of 

these maintenance operations may have 

created an unbalanced condition of the GG 

rotating assembly and, ultimately, failure of 

the GG rear bearing. 

This condition, if not detected and 

corrected, could lead to an uncommanded 

engine in-flight shut down and may 

ultimately lead to an emergency landing. 

You may obtain further information by 

examining the MCAI in the AD docket. 

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 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. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 1,445 products of U.S. 

registry. We also estimate that it would 

take about 1 work-hour per product to 

comply with this proposed AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

cost of the proposed AD on U.S. 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

56586 Federal Register / Vol. 77, No. 178 / Thursday, September 13, 2012 / Proposed Rules 

operators to be $122,825. Our cost 

estimate is exclusive of possible 

warranty coverage. 

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); and 

3. 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, 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: 

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 AD: 

Turbomeca S.A.: Docket No. FAA–2012– 

0901; Directorate Identifier 2012–NE– 

19–AD. 

(a) Comments Due Date 

We must receive comments by November 

13, 2012. 

(b) Affected Airworthiness Directives (ADs) 

None. 

(c) Applicability 

This AD applies to all Turbomeca S.A. 

ARRIEL 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 

1E2, 1K1, 1S, and 1S1 turboshaft engines. 

(d) Reason 

This AD was prompted by several reports 

of uncommanded in-flight shutdown on 

Arriel 1 engines. We are issuing this AD to 

prevent an uncommanded in-flight shutdown 

of the engine, which could result in an 

emergency landing. 

(e) Actions and Compliance 

Unless already done, from the effective 

date of this AD, do the following. After any 

Level 3 maintenance action on the gas 

generator (GG) rotating assembly and before 

returning the engine to service, accomplish a 

high GG speed (NG) rating vibration check. 

(f) Definition 

Level 3 maintenance on the GG rotating 

assembly is when the Module 03 is removed 

from the helicopter for implementation of 

deep maintenance operation to be performed 

in accordance with the applicable 

maintenance instructions. 

(g) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

may approve AMOCs for this AD. Use the 

procedures found in 14 CFR 39.19 to make 

your request.
