We propose to supersede airworthiness directive (AD) 2010-11- 10 that applies to all Turbomeca S.A., Astazou XIV B and XIV H turboshaft engines. AD 2010-11-10 requires inspection of certain third stage turbine wheels and removal of any damaged wheel. This AD was prompted by a report of a third stage turbine wheel crack detected during engine overhaul. This proposed AD would expand the population and frequency of repetitive inspections. We are proposing this AD to prevent uncontained failure of the third stage turbine wheel, which could result in damage to the engine and damage to the helicopter.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2010-11-
10 that applies to all Turbomeca S.A., Astazou XIV B and XIV H 
turboshaft engines. AD 2010-11-10 requires inspection of certain third 
stage turbine wheels and removal of any damaged wheel. This AD was 
prompted by a report of a third stage turbine wheel crack detected 
during engine overhaul. This proposed AD would expand the population 
and frequency of repetitive inspections. We are proposing this AD to 
prevent uncontained failure of the third stage turbine wheel, which 
could result in damage to the engine and damage to the helicopter.

Discussion

    On May 19, 2010, we issued AD 2010-11-10, Amendment 39-16315 (75 FR 
30270, June 1, 2010), (``AD 2010-11-10''), for all Turbomeca S.A., 
Astazou XIV B and XIV H turboshaft engines. AD 2010-11-10 requires 
inspection of

[[Page 12844]]

certain third stage turbine wheels and removal of any damaged wheel. AD 
2010-11-10 resulted from European Aviation Safety Agency (EASA) issuing 
an AD to identify and correct an unsafe condition on Turbomeca engines.
    We are issuing this AD to prevent uncontained failures of the third 
stage turbine wheel, which could result in damage to the engine and 
damage to the helicopter.

Actions Since AD 2010-11-10 Was Issued

    Since we issued AD 2010-11-10, Turbomeca reported a cracked third 
stage turbine wheel discovered during engine overhaul. As a result of 
the crack, Turbomeca S.A., expanded the population of affected wheels 
and inspection frequency. Turbomeca S.A., Mandatory Service Bulletin 
(MSB) No. 283 72 0804, Version D, dated July 24, 2015 addresses the 
increased population and inspection frequency. Also, since we issued AD 
2010-11-10, (EASA) has issued AD 2015-0211, dated October 15, 2015, 
which supersedes EASA AD 2010-0004, dated January 5, 2010.

Related Service Information Under 1 CFR Part 51

    Turbomeca S.A., has issued MSB No. 283 72 0804, Version D, dated 
July 24, 2015. That MSB describes procedures for expanding the 
frequency of repetitive inspections. 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 NPRM.

Other Related Service Information

    Turbomeca S.A., has issued Service Bulletin (SB) No. 283 72 0805, 
Version B, dated December 15, 2010. That SB describes terminating 
action for the inspections. 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 NPRM.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require expanding the frequency of 
repetitive inspections. We are proposing this AD to prevent uncontained 
failure of the third stage turbine wheel, which could result in damage 
to the engine, and damage to the helicopter.

Costs of Compliance

    We estimate that this proposed AD affects seven engines installed 
on helicopters of U.S. registry. We also estimate that it would take 
about 5 hours per engine to comply with this proposed AD. The average 
labor rate is $85 per hour. Based on these figures, we estimate the 
cost of this proposed AD on U.S. operators to be $2,975.

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 have 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 above, I certify that the 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.
