We are adopting a new airworthiness directive (AD) for certain Turbomeca S.A. Arriel 2B, 2B1, 2C, 2C1, 2C2, 2D, 2E, 2S1, and 2S2 turboshaft engines. This AD requires inspection, and, depending on the results, removal of the engine accessory gearbox (AGB). This AD was prompted by a report of an uncommanded in-flight shutdown (IFSD) of an Arriel 2 engine caused by rupture of the 41-tooth gear, which forms part of the bevel gear in the engine AGB. We are issuing this AD to prevent failure of the engine AGB, which could lead to in-flight shutdown, damage to the engine, and damage to the aircraft.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Turbomeca S.A. Arriel 2B, 2B1, 2C, 2C1, 2C2, 2D, 2E, 2S1, and 2S2 
turboshaft engines. This AD requires inspection, and, depending on the 
results, removal of the engine accessory gearbox (AGB). This AD was 
prompted by a report of an uncommanded in-flight shutdown (IFSD) of an 
Arriel 2 engine caused by rupture of the 41-tooth gear, which forms 
part of the bevel gear in the engine AGB. We are issuing this AD to 
prevent failure of the engine AGB, which could lead to in-flight 
shutdown, damage to the engine, and damage to the aircraft.

DATES: This AD becomes effective April 14, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 14, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM was published in the Federal Register on November 24, 2015 (80 FR 
73148). The NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:


[[Page 12584]]


    An uncommanded in-flight shut-down (IFSD) of an ARRIEL 2 engine 
was reported, caused by rupture of the 41-tooth gear, which forms 
part of the bevel gear of the accessory gearbox (module M01). The 
subsequent investigation revealed that wear on the housing of the 
front bearing of this gear was a major contributor to this rupture. 
In addition, the investigation showed that this wear mechanism had 
resulted in positive Spectrometric Oil Analysis (SOA) indications 
before the event.
    This condition, if not detected and corrected, could potentially 
lead to further cases of IFSD, possibly resulting in an emergency 
landing.

    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-2015-3753.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 73148, November 24, 
2015).

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed.

Related Service Information Under 1 CFR Part 51

    Turbomeca S.A. has issued Mandatory Service Bulletin No. 292 72 
2861, Version A, dated April 24, 2015. The service information 
describes procedures for inspecting the engine AGB. 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 final rule.

Costs of Compliance

    We estimate that this AD affects 250 engines installed on aircraft 
of U.S. registry. We also estimate that it will take about 0.5 hours 
per engine to comply with the initial inspection requirement in this AD 
and about 2 hours per engine to remove the engine AGB. The 
spectrometric oil analysis kit costs about $79. 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 $72,875.

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 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 this AD:
    (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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2016-04-12 Turbomeca S.A.: Amendment 39-18406; Docket No. FAA-2015-
3753; Directorate Identifier 2015-NE-26-AD.

(a) Effective Date

    This AD becomes effective April 14, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Turbomeca S.A. Arriel 2B, 2B1, 2C, 2C1, 2C2, 
2D, 2E, 2S1, and 2S2 turboshaft engines with an engine accessory 
gearbox (AGB), part number (P/N) 0292120650, with a machined front 
casing.

(d) Reason

    This AD was prompted by a report of an uncommanded in-flight 
shutdown (IFSD) of an Arriel 2 engine caused by rupture of the 41-
tooth gear, which forms part of the bevel gear in the engine AGB. We 
are issuing this AD to prevent failure of the engine AGB, which 
could lead to IFSD, damage to the engine, and damage to the 
aircraft.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(1) Initial Spectrometric Oil Analysis (SOA)

    (i) Perform an initial SOA within the compliance times given in 
paragraph (e)(1)(i)(A) or (e)(1)(i)(B) of this AD:
    (A) If the engine AGB has less than 800 engine hours (EHs) since 
new or since last overhaul, do an initial SOA before exceeding 850 
EHs since new or since last overhaul.
    (B) If the engine AGB has 800 EHs or more since new or since 
last overhaul, or if the EHs are unknown, do an initial SOA within 
50 EHs after the effective date of this AD.
    (C) Use paragraphs 2.4.2.1 and 2.4.2.2 of Turbomeca S.A. 
Mandatory Service Bulletin (MSB) No. 292 72 2861, Version A, dated 
April 24, 2015, to perform the SOA required by paragraph (e) of this 
AD.
    (ii) Reserved.

(2) Repetitive SOA

    (i) If the aluminum concentration determined from the most 
recent SOA is less than 0.8 parts per million (PPM), repeat the SOA 
required by paragraph (e) of this AD within 100 EHs time since last 
analysis (TSLA).
    (ii) If the aluminum concentration determined from the most 
recent SOA is between 0.8 PPM and 1.4 PPM, inclusive, repeat the SOA 
required by paragraph (e) of this AD within 50 EHs TSLA. Do not 
perform draining before doing the next SOA.
    (iii) If the aluminum concentration determined from the most 
recent SOA is greater than 1.4 PPM, remove the engine AGB from 
service within 50 EHs TSLA.

(f) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, FAA, may approve AMOCs 
for this AD. Use the procedures found in 14 CFR 39.19 to make your 
request. You may email your request to: [email protected].
