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.

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.

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.

[[Page 44840]]

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.
