We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A. MAKILA 2A and MAKILA 2A1 turboshaft engines. This proposed AD was prompted by two occurrences of crack initiation on a ferrule of the diffuser. This proposed AD would require repetitive diffuser inspections and replacement of those diffusers that fail inspection. We are proposing this AD to prevent rupture of the ferrule of the diffuser, which could result in engine fire and damage to the helicopter.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2015-0209, dated October 16, 2015 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

Two occurrences of crack initiation were reported on a ferrule of 
diffuser part number (P/N) 0298210100, which propagated and led to 
the ferrule rupture. The investigation shows in both cases that the 
ruptured ferrule contacted and punctured the main fuel supply line, 
resulting in a fuel leak. This condition, if not detected and 
corrected, could lead to an engine fire, consequently triggering an 
uncommanded engine in flight shut down, possibly resulting in an 
emergency landing. Prompted by these occurrences, Turbomeca 
published Mandatory Service Bulletin (MSB) No. 298 72 2832 to 
provide repetitive inspection instructions.

    This proposed AD would require repetitive inspections of the 
affected diffuser and removal of those diffusers that fail the required 
inspection. 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-2015-8257.

Related Service Information Under 1 CFR Part 51

    Turbomeca S.A. has issued Alert Mandatory Service Bulletin (MSB) 
No. A298 72 2832, Version B, dated October 12, 2015. The Alert MSB 
describes procedures for repetitive inspections of the affected 
diffuser and depending on findings, accomplishment of the corrective 
action(s).
    Turbomeca S.A. has issued Service Bulletin (SB) No. 298 72 2833, 
Version A, dated July 29, 2015. The SB identifies post-TU52 HP gas 
generator modules that have been released with a new ferrule after 
repair or overhaul in a Repair Center. When applying Alert Mandatory 
Service Bulletin (MSB) No. A298 72 2832, it is necessary to know if an 
HP gas generator module released by a Repair Center is equipped with a 
new ferrule.
    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 and Requirements of This Proposed AD

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with the European Community, EASA has notified us 
of the unsafe condition described in the MCAI and service information 
referenced above. We are proposing 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 products of the same type 
design. This proposed AD would require repetitive inspections of the 
affected diffuser and depending on findings, accomplishment of the 
corrective action(s).

Costs of Compliance

    We estimate that this proposed AD affects 10 engines installed on 
helicopters of U.S. registry. We also estimate that it would take about 
2 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 $1,700.

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 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,

[[Page 12836]]

    (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.
