Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

airworthiness directive (AD) 2014–19– 

05 for all Turbomeca S.A. Arriel 1A1, 

1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 

1K1, 1S, 1S1, 2B, 2B1, 2C, 2C1, 2C2, 

2S1, and 2S2 turboshaft engines. AD 

2014–19–05 required an initial one-time 

vibration check of the engine accessory 

gearbox (AGB) on certain Arriel 1 and 

Arriel 2 model engines, and repetitive 

vibration checks for all Arriel 1 and 

Arriel 2 engines. This AD was prompted 

by our determination that we incorrectly 

identified technical references in AD 

2014–19–05. We are issuing this AD to 

prevent failure of the engine AGB, 

which could lead to in-flight shutdown 

and damage to the engine, which may 

result in damage to the aircraft. 

DATES: This AD is effective September 1, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 1, 2015. 

The Director of the Federal Register 

approved the incorporation by reference

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2014–19–05, 

Amendment 39–17973 (79 FR 59091, 

October 1, 2014), (‘‘AD 2014–19–05’’). 

AD 2014–19–05 applied to the specified 

products. The NPRM published in the 

Federal Register on February 4, 2015 

(80 FR 6017). The NPRM proposed to 

continue to require an initial one-time 

vibration check of the engine AGB on 

certain higher risk Arriel 1 and Arriel 2 

model engines. That NPRM also 

proposed to continue to require 

repetitive vibration checks of the engine 

AGB for all Arriel 1 and Arriel 2 engines 

at every engine shop visit. 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Allow Sufficient 

Compliance Time 

One commenter requested that 

sufficient time be allowed to comply 

with this AD to account for the 

availability of the vibration test 

equipment and Turbomeca technical 

representatives. The commenter 

indicated that the initial one-time 

vibration check of the engine AGB 

requires use of Turbomeca-specified 

vibration test equipment and is 

performed by Turbomeca technical 

personnel. 

We do not agree. The compliance 

times in the AD provide sufficient time 

for the operator to perform the required 

maintenance. Operators can also 

procure the required vibration test 

equipment to perform the test. We did 

not change this AD. 

Request To Revise Definition of Shop 

Visit 

One commenter requested that we 

revise the AD to make the definition of 

‘‘shop visit’’ consistent with EASA AD 

2014–0036. The EASA AD specifies that 

the repetitive vibration check of the 

engine AGB be performed during a 

‘‘qualifying shop visit,’’ which is when 

the engine is ‘‘overhauled or repaired in 

a qualified Repair Center.’’ The 

commenter indicated that because of the 

modularity of the Arriel engine, it is 

possible to separate a major mating 

flange during ‘‘Level 2’’ or ‘‘Level 1 

maintenance.’’ 

We do not agree. We do not find 

specific criteria in EASA AD 2014– 

0036’s definition of ‘‘engine shop visit’’ 

for when the repetitive AGB vibration 

check should be conducted. We did not 

change this AD. 

Request To Eliminate Repetitive 

Vibration Check 

One commenter requested that the 

repetitive vibration check required by 

this AD be eliminated. The commenter 

indicated that this vibration check is 

already incorporated in Turbomeca 

Level 4 maintenance, and in subsequent 

test requirements, so it will always be 

done. Further, adding this requirement 

to the AD only adds to the cost and 

paperwork requirements for operators. 

We do not agree. The repetitive 

vibration checks of the engine AGB are 

required to prevent failure of the AGB. 

We did not change this AD. 

Revisions To Service Information 

References 

Turbomeca S.A. updated the service 

bulletins (SBs) referenced in this AD. 

We reviewed the updated SBs and 

found they adequately addressed the 

unsafe condition. Therefore, we revised 

this AD to reference the updated 

versions of the SBs. This AD now 

references Turbomeca S.A. Mandatory 

Service Bulletin (MSB) No. 292 72 0839, 

Version C, dated June 18, 2014, and 

Turbomeca S.A. MSB No. 292 72 2849, 

Version C, dated June 18, 2014. We also 

revised compliance paragraph (e) of this 

AD to refer to the corresponding 

paragraphs used in these updated MSBs 

to require the vibration checks. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of 

this AD.

Related Service Information Under 1 

CFR Part 51 

We reviewed Turbomeca S.A. MSB 

No. 292 72 0839, Version C, dated June 

18, 2014; and Turbomeca S.A. MSB No. 

292 72 2849, Version C, dated June 18, 

2014. The service information describes 

procedures for vibration checks. 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 AD. 

Costs of Compliance 

We estimate that this AD affects 1,268 

engines installed on aircraft of U.S. 

registry. We also estimate that it will 

take about 4 hours per engine to comply 

with the inspection requirement in this 

AD. The average labor rate is $85 per 

hour. Based on these figures, we 

estimate the cost of this AD on U.S. 

operators to be $431,120. 

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 

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.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part, A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it amends 

Class E airspace at Headland Municipal 

Airport, Headland, AL. 

History 

On April 24, 2015, the FAA published 

in the Federal Register a notice of 

proposed rulemaking (NPRM) to 

establish Class E airspace extending 

upward from 700 feet above the surface 

at Headland Municipal Airport, 

Headland, AL (80 FR 22946). Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal to the 

FAA. No comments were received. 

Class E airspace designations are 

published in paragraph 6005 of FAA 

Order 7400.9Y dated August 6, 2014, 

and effective September 15, 2014, which 

is incorporated by reference in 14 CFR
