30 Federal Register / Vol. 81, No. 1 / Monday, January 4, 2016 / Proposed Rules 

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; 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.

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 2E turboshaft 

engines. This proposed AD was 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 81, No. 1 / Monday, January 4, 2016 / Proposed Rules 31 

prompted by reports of fuel flow nonconformities found during acceptance 

tests of Arriel 2E hydro-mechanical 

metering units (HMUs). This proposed 

AD would require removing the pre-TU 

193 adjusted high-pressure/lowpressure (HP/LP) pump and metering 

valve assembly and replacing it with a 

part that is eligible for installation. This 

proposed AD would also require 

replacing the constant delta-pressure 

(delta-P) diaphragm of the fuel metering 

valve. We are proposing this AD to 

prevent failure of the delta-P diaphragm, 

which could result in an uncommanded 

in-flight shutdown and damage to the 

helicopter. 

DATES: We must receive comments on 

this proposed AD by March 4, 2016.

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– 

0213, dated October 16, 2015 (referred 

to hereinafter as ‘‘the MCAI’’), 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. 

This proposed AD applies to Arriel 2E 

engines only. There are no Arriel 2N 

engines installed on aircraft of U.S. 

registry. 

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. 

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. 

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 referenced above. We are 

proposing this NPRM 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 NPRM would require 

removing the pre-TU 193 adjusted HP/ 

LP pump and metering valve assembly 

and replacing it with a part that is 

eligible for installation. This NPRM 

would also require replacing the 

constant delta-P diaphragm of the fuel 

metering valve. 

Costs of Compliance 

We estimate that this proposed AD 

affects 12 engines installed on 

helicopters of U.S. registry. We also 

estimate that it would take about 2 

hours per engine to comply with this 

proposed 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 

proposed 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. 


tkelley on DSK3SPTVN1PROD with PROPOSALS
32 Federal Register / Vol. 81, No. 1 / Monday, January 4, 2016 / Proposed Rules 

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.

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B16 

(CL–604 Variant) airplanes. This 

proposed AD was prompted by a 

determination that certain maintenance

proposed AD would require revising the 

maintenance or inspection program, as 

applicable, to incorporate new 

airworthiness limitations for the HSTA. 

We are proposing this AD to detect and 

correct premature wear and cracking of 

the HSTA, which could result in failure 

of the HSTA and consequent loss of 

control of the airplane.
