[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

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.
