AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for Airbus 

Helicopters Model AS332C, AS332L, 

AS332L1, AS332L2, EC225LP, and 

SA330J helicopters with a certain tail 

rotor control turnbuckle (turnbuckle) 

installed. This AD requires inspecting 

the turnbuckles for corrosion or a crack, 

and depending on the results, either 

replacing the turnbuckle or treating the 

turnbuckle for corrosion. This AD was 

prompted by a report that a turnbuckle 

had failed because of corrosion. The 

actions of this AD are intended to detect 

corrosion or a crack on a turnbuckle and 

prevent the failure of a turnbuckle, loss 

of control of the tail rotor and 

subsequent loss of control of the 

helicopter. 

DATES: This AD is effective April 15, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain documents listed in this AD 

as of April 15, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

On October 24, 2013, at 78 FR 63429, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 by adding an AD that would apply 

to Eurocopter France (now Airbus 

Helicopters) Model AS332C, AS332L, 

AS332L1, AS332L2, EC225LP, and 

SA330J helicopters with a turnbuckle, 

part number (P/N) 330A27–5031–20, 

installed. The NPRM proposed to 

require inspecting the turnbuckles for 

corrosion or a crack, and depending on 

the results, either replacing the 

turnbuckle or treating the turnbuckle for 

corrosion. The proposed requirements 

were intended to detect corrosion or a 

crack on a turnbuckle and prevent the 

failure of a turnbuckle, loss of control of 

the tail rotor and subsequent loss of 

control of the helicopter. 

The NPRM was prompted by AD No. 

2013–0081, dated March 26, 2013, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union. EASA published AD 

No. 2013–0081 to correct an unsafe 

condition for Eurocopter Model SA330J, 

AS332C, AS332C1, AS332L, AS332L1, 

AS332L2, EC225LP helicopters 

equipped with tail rotor control 

turnbuckles, part number 330A27– 

5031–20. EASA advises that one of the 

two turnbuckles installed on the tail 

rotor’s yaw flight control cables failed 

on a helicopter because of corrosion. 

The subsequent investigation revealed a 

lack of Mastinox sealant coating 

between both sides of the turnbuckle’s 

internal tappings and the interface 

screws of the end-fitting components of 

the yaw flight control cables. To address 

this condition, EASA issued AD No. 

2013–0081, which requires repetitive 

inspections of each turnbuckle and, 

depending on the results, either 

replacing the turnbuckle or treating the 

turnbuckle for corrosion. EASA revised 

its AD and issued AD No. 2013–0081R1, 

dated June 20, 2013, to clarify some of 

the requirements. 

mstockstill on DSK4VPTVN1PROD with RULES

13520 Federal Register / Vol. 79, No. 47 / Tuesday, March 11, 2014 / Rules and Regulations 

Since we issued the NPRM, 

Eurocopter France changed its name to 

Airbus Helicopters. This AD reflects 

that change and updates the contact 

information to obtain service 

documentation. 

Comments 

We gave the public the opportunity to 

participate in developing this AD, but 

we received no comments on the NPRM 

(78 FR 63429, October 24, 2013). 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of France and 

are approved for operation in the United 

States. Pursuant to our bilateral 

agreement with France, EASA, its 

technical representative, has notified us 

of the unsafe condition described in the 

EASA AD. We are issuing 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 helicopters of 

the same type designs and that air safety 

and the public interest require adopting 

the AD requirements as proposed except 

for the minor change previously 

described. This change is consistent 

with the intent of the proposals in the 

NPRM (78 FR 63429, October 24, 2013) 

and will not increase the economic 

burden on any operator nor increase the 

scope of the AD. 

Differences Between This AD and the 

EASA AD 

The EASA AD applies to Eurocopter 

Model AS332C1 helicopters. This AD 

does not because Model AS332C1 

helicopters are not type certificated in 

the United States. 

Related Service Information 

On March 14, 2013, Eurocopter issued 

Alert Service Bulletin (ASB) No. EC225– 

05A031 for Model No. EC225LP 

helicopters; ASB No. AS332–05.00.95 

for Model AS332C, AS332C1, AS332L, 

AS332L1 and AS332L2 and for military 

Model AS332B, AS332B1, AS332F1, 

AS332M and AS332M1 helicopters; and 

ASB No. SA330–05.98 for Model 

SA330J and military Model SA330Ba, 

SA330Ca, SA330Ea, SA330H, SA330L, 

SA330Jm, SA330S1 and SA330Sm 

helicopters. Eurocopter reports that a 

tail rotor control turnbuckle ruptured 

because of corrosion. The damage was 

discovered during a flight-control check 

after the main gearbox was replaced. An 

investigation revealed that Mastinox 

sealant was missing between the 

turnbuckle tappings and end-fittings 

and led to the formation of galvanic 

corrosion. To prevent a turnbuckle from 

splitting, Eurocopter called for checking 

all tail rotor control turnbuckles for 

cracks and corrosion every 12 months. 

On June 5, 2013, Eurocopter revised all 

of the ASBs with Revision 1 to clarify 

a requirement. 

Costs of Compliance 

We estimate that this AD affects 46 

helicopters of U.S. Registry and that 

labor costs average $85 a work-hour. 

Based on these estimates, we expect the 

following costs: 

• Inspecting the tail rotor control 

turnbuckles for corrosion or a crack 

requires 4 work-hours for a labor cost of 

$340. Parts cost $148 for a total cost of 

$488 per helicopter, $22,448 for the U.S. 

fleet. 

• Treating the turnbuckle to prevent 

corrosion require 1 work-hour for a 

labor cost of $85. The cost of parts is 

minimal for a total cost of $85 per 

helicopter. 

• Replacing the turnbuckle requires 

no additional labor costs because it can 

be done as part of the inspection. Parts 

cost $173 for a total cost of $173 per 

helicopter. 

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 

helicopters identified in this rulemaking 

action. 

Regulatory Findings 

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 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 this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

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 AD and placed it in the AD docket.
