Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD No. 2013– 

0177, dated August 8, 2013, to correct 

an unsafe condition for Agusta Model 

AB139 and AW139 helicopters. EASA 

advises that leaking hydraulic system 

flexible hoses have been reported on inservice helicopters. An investigation 

indicated that single braided flexible 

hydraulic hoses, which are part of the 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 136 / Wednesday, July 16, 2014 / Proposed Rules 41465 

original design for Model AB139 and 

AW139 helicopters, may not be strong 

enough to cope with the hydraulic 

system pressure over long periods. If not 

corrected, this condition could lead to 

other hydraulic system leaks, possibly 

resulting in loss of hydraulic power and 

reduced control of the helicopter, EASA 

advises. EASA consequently requires 

that the flexible single-braided 

hydraulic hoses be replaced with 

flexible double-braided hydraulic hoses. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Italy and are 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Italy, EASA, its 

technical representative, has notified us 

of the unsafe condition described in its 

AD. We are proposing this AD because 

we evaluated all known relevant 

information and determined that an 

unsafe condition is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information 

AgustaWestland Bolletino Tecnico 

No. 139–307, dated June 19, 2013 (BT), 

calls for replacing certain single braided 

flexible hydraulic hoses with double 

braided flexible hydraulic hoses for 

Model AB139 and AW139 helicopters. 

The BT states that the replacement 

should be conducted within 300 flight 

hours or six months from receipt of the 

BT, whichever comes first, to prevent 

in-service leaks. 

Proposed AD Requirements 

This proposed AD would require, 

within 300 hours time-in-service (TIS), 

replacing the flexible single-braided 

hydraulic hose with a flexible doublebraided hydraulic hose. The AD would 

also prohibit installing the singlebraided flexible hydraulic hose on any 

helicopter. 

Differences Between This Proposed AD 

and the EASA AD 

The EASA AD requires replacing the 

flexible single-braided hydraulic hoses 

within 300 flight hours or 6 months, 

whichever occurs first. This proposed 

AD requires that the flexible singlebraided hydraulic hoses be replaced 

within 300 hours TIS. TIS and flight 

hours are synonymous. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 115 helicopters of U.S. 

Registry and that labor costs average $85 

per work-hour. Based on these 

estimates, we expect that replacing the 

flexible single-braided hydraulic hoses 

with flexible double-braided hydraulic 

flexible hoses would require 6 workhours for a labor cost of $510. Parts 

would cost $3,089 for a total cost of 

$3,599 per helicopter, and $413,885 for 

the U.S. fleet. 

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, 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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

Discussion 

On August 21, 2013, we issued AD 

2013–18–01, amendment 39–17574 (78 

FR 56599, September 13, 2013) for 

Eurocopter France Model EC 155B, 

EC155B1, SA–365N, SA–365N1, AS– 

365N2, AS 365 N3, and SA–366G1 

helicopters, except helicopters with 

modification (MOD) 0767B5 installed. 

AD 2013–18–01 requires inspecting the 

collective pitch lever for correct 

unlocking with a spring scale, and if 

required, adjusting the collective pitch 

lever restraining tab and, for certain 

models, adjusting the collective link 

rods. AD 2013–18–01 also requires 

inspecting the collective pitch lever for 

the risk of inadvertent locking by 

measuring the clearance between the 

locking pin of the collective pitch lever 

and the L-section of the restraining tab, 

and if required, modifying the tab with 

a slight bend to the tab. 

AD 2013–18–01 was prompted by AD 

No. 2011–0154, dated August 22, 2011, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union. EASA issued AD 

2011–0154 to correct an unsafe 

condition for Eurocopter Model EC 

155B, EC155B1, SA–365N, SA–365N1, 

AS–365N2, AS 365 N3, and SA–366G1 

helicopters. EASA advises that two 

occurrences have been reported of 

inadvertent locking and unlocking of 

the collective pitch lever. One 

inadvertent collective pitch lever 

locking occurred when moving the 

collective pitch lever to the low-pitch 

position, and one inadvertent collective 

pitch lever unlocking occurred during
