Airworthiness Directives; Kelly Aerospace Energy Systems, LLC
Rebuilt Turbochargers
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Kelly Aerospace Energy Systems, LLC (KAES) rebuilt
turbochargers. This AD requires removal from service of certain part
number (P/N) and serial number (S/N) rebuilt turbochargers. This AD
results from three reports of infant mortality turbine wheel failure in
rebuilt turbochargers, since June of 2007. We are issuing this AD to
prevent separation or seizure of the turbocharger turbine, which could
result in full or partial engine power loss, loss of engine oil, and
smoke in the airplane cabin.
DATES: This AD becomes effective April 19, 2010. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of April 19, 2010.
We must receive any comments on this AD by June 1, 2010.

SUPPLEMENTARY INFORMATION: In October 2009, we were made aware by KAES
that since June 2007, three turbochargers rebuilt by KAES have failed.
Two had turbine wheel head separation and the third had a turbine shaft
seizure. Investigation revealed that a steel wire brush was used to
remove the accumulated coking that had built up on these turbine wheels
being reclaimed for re-use in rebuilt turbochargers. This procedure
created a rough surface finish on the turbine wheel shaft that exceeded
allowable limits. The rough surface finish can disrupt the required
formation of a hydrodynamic layer of oil between the shaft and mating
bearings. This condition, if not corrected, could result in separation
or seizure of the turbocharger turbine, which could result in full or
partial engine power loss, loss of engine oil, and smoke in the
airplane cabin.
Relevant Service Information
We have reviewed and approved the technical contents of Kelly
Aerospace Energy Systems, LLC Service Bulletin (SB) No. 039 A, dated
February 10, 2010. That SB identifies the rebuilt turbochargers by P/N
and S/N that are suspect of having a rough shaft surface finish
exceeding allowable limits.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other KAES rebuilt turbochargers of the same type design.
For that reason, we are issuing this AD to prevent separation or
seizure of the turbocharger turbine, which could result in full or
partial engine power loss, loss of engine oil, and smoke in the
airplane cabin. This AD requires removal from service of certain P/N
and S/N rebuilt turbochargers. You must use the service information
described previously to determine what S/N rebuilt turbochargers are
affected by this AD.
FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate
adoption of this AD, we have found that notice and opportunity for
public comment before issuing this AD are impracticable, and that good
cause exists for making this amendment effective in less than 30 days.
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 send us any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. FAA-2009-1259;
Directorate Identifier 2009-NE-41-AD'' in the subject line of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it.
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
[[Page 16663]]
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).
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is the same as
the Mail address provided in the ADDRESSES section. Comments will be
available in the AD docket shortly after receipt.
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 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 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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.
