Airworthiness Directives; Wytwornia Sprzetu Komunikacyjnego (WSK)
PZL-10W Turboshaft Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Wytwornia Sprzetu Komunikacyjnego
[[Page 52834]]
(WSK) PZL-10W turboshaft engines. This AD requires a one-time
inspection of the four engine-to-gearbox pin retaining joints for loose
or improperly crimped retaining nuts and damaged bolts on certain
serial number engines. This AD is prompted by reports of loose or
improperly crimped engine-to-gearbox pin joint retaining nuts found
during overhaul. We are issuing this AD to prevent loss of nut torque
and loosening of engine-to-gearbox pin joint retaining nuts, which
could result in misalignment of the engine to the gearbox, causing loss
of drive to the gearbox, power turbine overspeed, and uncontained power
turbine disc failure.
DATES: Effective September 23, 2003. The Director of the Federal
Register approved the incorporation by reference of certain
publications listed in the regulations as of September 23, 2003.
We must receive any comments on this AD by November 7, 2003.
ADDRESSES: Use one of the following addresses to submit comments on

SUPPLEMENTARY INFORMATION: The Polish General Inspectorate of Civil
Aviation, which is the airworthiness authority for Poland, recently
notified the FAA that an unsafe condition may exist on Wytwornia
Sprzetu Komunikacyjnego (WSK) PZL-10W turboshaft engines. The Polish
General Inspectorate of Civil Aviation advises that reports have been
received of loose or improperly crimped engine-to-gearbox pin joint
retaining nuts and damaged bolts found during overhaul.
Relevant Service Information
We have reviewed and approved the technical contents of Wytwornia
Sprzetu Komunikacyjnego Obligatory Service Bulletin (OSB) No. E-19W096/
2000, (original issue--2000), that describes procedures for performing
a one-time inspection of the four engine-to-gearbox pin retaining
joints for loose or improperly crimped retaining nuts and damaged bolts
on the serial number PZL-10W engines listed in the OSB. The Polish
General Inspectorate of Civil Aviation classified this OSB as mandatory
and issued AD No. SP-0008-2001-B, dated October 2, 2001.
Bilateral Airworthiness Agreement
This engine model is manufactured in Poland and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Under this bilateral
airworthiness agreement, the Polish General Inspectorate of Civil
Aviation has kept the FAA informed of the situation described above. We
have examined the findings of the Polish General Inspectorate of Civil
Aviation, reviewed all available information, and determined that AD
action is necessary for products of this type design that are
certificated for operation in the United States.
FAA's Determination and Requirements of This AD
Although no helicopters that are registered in the United States
use these PZL-10W turboshaft engines, the possibility exists that the
PZL-10W turboshaft engines could be used on helicopters that are
registered in the United States in the future. The unsafe condition
described previously is likely to exist or develop on other WSK PZL-10W
turboshaft engines of the same type design. We are issuing this AD to
prevent loss of nut torque and loosening of engine-to-gearbox pin joint
retaining nuts, which could result in misalignment of the engine to the
gearbox, causing loss of drive to the gearbox, power turbine overspeed,
and uncontained power turbine disc failure. This AD requires performing
a one-time inspection of the four engine-to-gearbox pin retaining
joints for loose or improperly crimped retaining nuts and damaged bolts
on the serial number PZL-10W engines listed in OSB No. E-19W096/2000,
(original issue--2000). You must use the service information described
previously to perform the actions required by this AD.
FAA's Determination of the Effective Date
Since there are currently no domestic operators of this engine
model, notice and opportunity for public comment before issuing this AD
are unnecessary. Therefore, a situation exists that allows the
immediate adoption of this regulation.
Changes to 14 CFR Part 39--Effect on the AD
On July 10, 2002, we issued a new version of 14 CFR part 39 (67 FR
47997, July 22, 2002), which governs our AD system. This regulation now
includes material that relates to special flight permits, alternative
methods of compliance, and altered products. This material previously
was included in each individual AD. Since this material is included in
14 CFR part 39, we will not include it in future AD actions.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment; however, we invite you to submit any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. 2003-NE-30-AD'' in the
subject line of your comments. If you want us to acknowledge receipt of
your mailed comments, send us a self-addressed, stamped postcard with
the docket number written on it; we will date-stamp your postcard and
mail it back to you. We specifically invite comments on the overall
regulatory, economic, environmental, and energy aspects of the rule
that might suggest a need to modify it. If a person contacts us
verbally, and that contact relates to a substantive part of this AD, we
will summarize the contact and place the summary in the docket. We will
consider all comments received by the closing date and may amend the AD
in light of those comments.
We are reviewing the writing style we currently use in regulatory
documents. We are interested in your comments on whether the style of
this document is clear, and your suggestions to improve the clarity of
our communications with you. You may get more information about plain
language at http://www.faa.gov/language and http://www.plainlanguage.gov

Examining the AD Docket
You may examine the AD Docket (including any comments and service
information), by appointment, between 8:00 a.m. and 4:30 p.m., Monday
through Friday, except Federal holidays. See ADDRESSES for the
location.
Regulatory Findings
We have 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 that the 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); 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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket No. 2003-NE-30-AD'' in your request.
