RIN 2120–AA64 

Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Turbomeca S.A. Arriel 2E turboshaft 

engines. This AD requires removing the 

pre-TU 193 adjusted high-pressure/lowpressure pump and metering valve 

assembly and replacing it with a part 

that is eligible for installation. This AD 

also requires replacing the constant 

delta-pressure (delta-P) diaphragm of 

the fuel metering valve. This AD was 

prompted by reports of fuel flow nonconformities found during acceptance 

tests of Arriel 2E hydro-mechanical 

metering units (HMUs). We are issuing 

this AD to prevent failure of the deltaP diaphragm, which could result in an 

uncommanded in-flight shutdown and 

damage to the helicopter. 

DATES: This AD becomes effective May 

25, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on January 4, 2016 (81 FR 30). 

The NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Fuel flow non-conformities were found 

during reception tests of ARRIEL 2E 

Hydraulic Mechanical Metering Unit (HMU). 

Investigation and instrumented tests revealed 

instabilities on the additional check valve. 

These instabilities lead to hydraulic pulses. 

All HMU installed on ARRIEL 2E and 2N 

engines could present these instabilities. 

This condition, if not corrected, could lead 

to life reduction of the delta pressure valve 

diaphragm, and consequently, an 

uncommanded engine power increase, or an 

uncommanded in flight shutdown, possibly 

resulting in an emergency landing. 

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– 

5539. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (81 

FR 30, January 4, 2016). 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed. 

Related Service Information 

Turbomeca S.A. has issued 

Mandatory Service Bulletin (MSB) No. 

292 73 2193, Version A, dated July 16, 

2015. The MSB describes procedures for 

incorporating modification TU 193 and 

replacing the constant delta-P 

diaphragm of the fuel metering valve. 

Costs of Compliance 

We estimate that this AD affects 12 

engines installed on helicopters of U.S. 

registry. We also estimate that it will 

take about 2 hours per engine to comply 

with this AD. The average labor rate is 

$85 per hour. Required parts cost about 

$13,400 per engine. Based on these 

figures, we estimate the cost of this AD 

on U.S. operators to be $162,840. 

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 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 


Lhorne on DSK5TPTVN1PROD with RULES
23156 Federal Register / Vol. 81, No. 76 / Wednesday, April 20, 2016 / Rules and Regulations 

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 AD: 

(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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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): 

2016–08–16 Turbomeca S.A.: Amendment 

39–18493; Docket No. FAA–2015–5539;

(d) Reason 

This AD was prompted by reports of fuel 

flow non-conformities found during 

acceptance tests of Arriel 2E hydromechanical metering units. We are issuing 

this AD to prevent failure of the constant 

delta-pressure (delta-P) diaphragm of the fuel 

metering valve, which could result in an 

uncommanded in-flight shutdown and 

damage to the helicopter. 

(e) Actions and Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) Prior to exceeding 880 operating hours 

since new on the adjusted HP/LP pump and

LP pump and metering valve assembly and 

replace with a part that is eligible for 

installation, and 

(ii) replace the constant delta-P diaphragm 

of the fuel metering valve. 

(2) Reserved. 

(f) Installation Prohibition 

After the effective date of this AD, do not 

install into any engine any pre-TU 193 

adjusted HP/LP pump and metering valve 

assembly, nor install onto any helicopter any 

engine that has a pre-TU 193 adjusted HP/LP 

pump and metering valve assembly.

Establishment of the Lewis-Clark 

Valley Viticultural Area and 

Realignment of the Columbia Valley 

Viticultural Area 

AGENCY: Alcohol and Tobacco Tax and 

Trade Bureau, Treasury. 

ACTION: Final rule; Treasury decision. 

SUMMARY: The Alcohol and Tobacco Tax 

and Trade Bureau (TTB) establishes the 

approximately 306,650-acre Lewis-Clark 

Valley viticultural area in portions of 

Nez Perce, Lewis, Clearwater, and Latah 

Counties in Idaho and Asotin, Garfield, 

and Whitman Counties in Washington. 

TTB is also modifying the boundary of 

the existing Columbia Valley 

viticultural area to eliminate a partial 

overlap with the Lewis-Clark Valley 

viticultural area. The boundary 

modification will decrease the size of 

the approximately 11,370,320-acre 

Columbia Valley viticultural area by 

approximately 57,020 acres. The LewisClark Valley viticultural area is not 

located within and does not overlap any 

other viticultural area. TTB designates 

viticultural areas to allow vintners to 

better describe the origin of their wines 

and to allow consumers to better 

identify wines they may purchase. 

DATES: This final rule is effective May 

20, 2016.
