Airworthiness Directives; WYTWORNIA SPRZETU KOMUNIKACYJNEGO (WSK) 
``PZL-RZESZOW''--SPOLKA AKCYJNA (SA) PZL--10W Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    An uncommanded engine in-flight shutdown of a PZL-10W has been 
recently reported. The investigation has shown that the uncommanded 
engine in-flight shutdown was due to excessive spline wear on the 
fuel metering pump shaft.
    This condition, if not identified and corrected, may lead to 
further uncommanded in-flight engine shutdowns and consequent 
emergency landings of the affected helicopters.

    We are issuing this AD to prevent uncommanded engine in-flight 
shutdown and risk to the helicopter.

DATES: This AD becomes effective October 4, 2011.
    We must receive comments on this AD by October 19, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of WSK Obligatory Bulletin No. E-19W147B/DOA/2010 (this 
bulletin has no issue date), listed in the AD as of October 4, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2011-0030, dated February 25, 2011, (referred 
to after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    An uncommanded engine in-flight shutdown of a PZL-10W has been 
recently reported. The investigation has shown that the uncommanded 
engine in-flight shutdown was due to excessive spline wear on the 
fuel metering pump shaft.
    This condition, if not identified and corrected, may lead to 
further uncommanded in-flight engine shutdowns and consequent 
emergency landings of the affected helicopters.
    To address this unsafe condition, WSK ``PZL-Rzesz[oacute]w'' 
S.A. has developed an inspection programme of the fuel metering pump 
shaft.
    For the reasons described above, this AD requires an inspection 
of the fuel metering pump shaft and the accomplishment of the 
associated corrective actions, as applicable.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    WSK ``PZL-Rzesz[oacute]w'' S.A has issued Obligatory Bulletin No. 
E-19W147B/DOA/2010 (this bulletin has no issue date). The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of Poland, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with EASA, they have notified us of the unsafe 
condition described in the MCAI and service information referenced 
above. We are issuing 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.

FAA's Determination of the Effective Date

    Since no domestic operators use this product, notice and 
opportunity for public comment before issuing this AD are unnecessary. 
Therefore, we are adopting this regulation immediately.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2011-0760; Directorate 
Identifier 2011-NE-10-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact 
with FAA personnel concerning this AD. Using the search function of the 
Web site, anyone can find and read the comments in any of our dockets, 
including, if provided, the name of the individual who sent the comment 
(or signed the comment on behalf of an association, business, labor

union, etc.). You may review the DOT's complete Privacy Act Statement 
in the Federal Register published on April 11, 2000 (65 FR 19477-78).

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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
