[Docket No. FAA-2007-28863; Directorate Identifier 2007-NE-33-AD;
Amendment 39-15149; AD 2007-16-10]

Airworthiness Directives; Teledyne Continental Motors
Reciprocating (TCM) Engine Models IO-550-N, TSIO-520-BE, TSIO-550-A,
TSIO-550-B, TSIO-550-C, TSIO-550-E, and TSIO-550-G
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for TCM
IO-550-N, TSIO-520-BE, TSIO-550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E,
and TSIO-550-G reciprocating engines. This AD requires removing before
further flight, certain Kelly Aerospace Power Systems turbochargers,
part number (P/N) 466304-0003, listed by serial number in this AD. This
AD results from four incidents of the turbine rotor separating from the
shaft of the turbocharger. We are issuing this AD to prevent the
turbine rotor from separating from the shaft of the turbocharger due to
a machining defect in the turbocharger compressor. This condition could
result in full engine power loss, loss of engine lubricant, or smoke in
the airplane cabin.
DATES: This AD becomes effective August 23, 2007. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of August 23, 2007.
We must receive any comments on this AD by October 9, 2007.

SUPPLEMENTARY INFORMATION: On July 16, 2007, Kelly Aerospace Power
Systems informed us that there were potential nonconforming
turbochargers, P/N 466304-0003 that might have a machining defect in
the compressors of the turbochargers. A machining defect in the
turbocharger compressor leads to a condition where the center bore of
the compressor is not perpendicular to the backface of the compressor.
The machining defect leads to abnormal turbocharger rotor vibration
which results in abnormal wear characteristics. The wear could result
in the turbocharger rotor separating from the shaft. This condition, if
not corrected, could result in full engine power loss, loss of engine
lubricant, or smoke in the airplane cabin.
Relevant Service Information
We have reviewed and approved the technical contents of Kelly
Aerospace Power Systems Service Bulletins (SBs) No. 026, Revision B,
dated July 27, 2007, and No. 027, dated July 25, 2007. Those SBs list
affected turbochargers by SN, and describe procedures for visually
inspecting the turbocharger.
FAA's Determination and Requirements of this AD
The unsafe condition described previously is likely to exist or
develop on other engines of the same type design. For that reason, we
are issuing this AD to prevent the turbine rotor from separating from
the shaft of the turbocharger due to a machining defect in the
turbocharger compressor. This condition could result in full engine
power loss, loss of engine lubricant, or smoke in the airplane cabin.
This AD requires replacing certain turbochargers before further flight.
You must use the service information described previously to perform
the actions required 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-2007-28863;
Directorate Identifier 2007-NE-33-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://dms.dot.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 DMS Web
site, anyone can find and read the comments in any of our dockets,
including 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) or you may visit
http://dms.dot.gov.
Examining the AD Docket
You may examine the AD docket on the Internet at http://dms.dot.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 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
[[Page 44371]]
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.
