Airworthiness Directives; Kelly Aerospace Power Systems
Turbochargers
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
certain Kelly Aerospace Power Systems turbochargers. This AD requires a
onetime visual inspection of suspect turbochargers for an excessive gap
between the turbocharger turbine housing flange and the exhaust tube
flange, and replacement of turbochargers that fail the gap inspection.
This AD results from two reports of exhaust leakage occurring between
the turbocharger turbine housing flange and the exhaust tube flange due
to machining defects of the turbocharger turbine housing flange. We are
issuing this AD to prevent hazardous amounts of carbon monoxide from
entering the cabin, an increase in under-cowl temperatures hampering
engine and accessory function, and loss of tailpipe retention, which
could lead to an in-flight fire and loss of control of the airplane.
DATES: This AD becomes effective May 6, 2008. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of May 6, 2008.
We must receive any comments on this AD by June 20, 2008.

SUPPLEMENTARY INFORMATION: In January 2008, Lycoming Engines notified
us, and Kelly Aerospace Power Systems, of two reports of exhaust
leakage occurring between the turbocharger turbine housing flange and
the exhaust tube flange. Lycoming Engines found machining defects in
the turbine housing exit flanges of those Kelly Aerospace Power Systems
turbochargers. Kelly Aerospace Power Systems investigated this quality
escape, and found that the same machining defect may exist on as many
as 310 turbochargers. This condition, if not corrected, could result in
hazardous amounts of carbon monoxide entering the cabin and an increase
in under-cowl temperatures hampering engine and accessory function.
This condition could also result in loss of tailpipe retention, which
could lead to an in-flight fire and loss of control of the airplane.
Relevant Service Information
We have reviewed and approved the technical contents of Lycoming
Engines Mandatory Service Bulletin (MSB) No. 580, dated February 15,
2008, Kelly Aerospace Power Systems MSB No. 029, dated February 1,
2008, Kelly Aerospace Power Systems MSB No. 030, Revision A, dated
April 1, 2008, and Kelly Aerospace Power Systems MSB No. 031, dated
February 28, 2008. These MSBs list affected engine model numbers and
suspect turbocharger part numbers and serial numbers.
FAA's Determination and Requirements of this AD
The unsafe condition described previously is likely to exist or
develop on other Kelly Aerospace Power Systems turbochargers of the
same type design. For that reason, we are issuing this AD to prevent
hazardous amounts
[[Page 21223]]
of carbon monoxide from entering the cabin, an increase in under-cowl
temperatures hampering engine and accessory function, and loss of
tailpipe retention, which could lead to an in-flight fire and loss of
control of the airplane. This AD requires a onetime visual inspection
of suspect turbochargers for an excessive gap between the turbocharger
turbine housing flange and the exhaust tube flange, and replacement of
turbochargers that fail the gap inspection. You must use the service
information previously described to identify the suspect population of
turbochargers 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. 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-2008-0314;
Directorate Identifier 2008-NE-09-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 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.

Unsafe Condition
(d) This AD results from two reports of exhaust leakage
occurring between the turbocharger turbine housing flange and the
exhaust tube flange due to machining defects of the turbocharger
turbine housing flange. We are issuing this AD to prevent hazardous
amounts of carbon monoxide from entering the cabin, an increase in
under-cowl temperatures hampering engine and accessory function, and
loss of tailpipe retention, which could lead to an in-flight fire
and loss of control of the airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within 10 hours time-in-service or at the next regular
inspection interval, whichever occurs first, unless the actions have
already been done.
Onetime Visual Inspection of Turbocharger
(f) Carefully remove the ``V'' band clamp from around the
turbocharger turbine housing at the turbocharger exhaust outlet,
taking care not to move the exhaust tube and tailpipe assembly.
(g) Visually inspect the area that was captured by the ``V''
band clamp. Use a feeler gauge at the split line between the turbine
housing flange and the exhaust tube flange all around the
circumference.
(h) The maximum gap must not exceed 0.005 inch.
(i) Before further flight, replace any turbocharger that exceeds
the 0.005 inch maximum gap, with a serviceable turbocharger.
(j) If the maximum gap is not exceeded, metal stamp a 1/8''
upper case ``I'' on the side of the turbocharger discharge flange.
Information on the stamping location can be found in the MSBs
referenced in this AD.
Definition
(k) For the purpose of this AD, a serviceable turbocharger is
one that is not listed in the suspect SN lists of the Lycoming
Engines MSB or KAPS MSBs referenced in this AD, or one that passes
the visual inspection in this AD.
Alternative Methods of Compliance
(l) The Manager, Atlanta Aircraft Certification Office, has the
authority to approve alternative methods of compliance for this AD
if requested using the procedures found in 14 CFR 39.19.
Special Flight Permits
(m) Under 39.23, we are limiting the special flight permits for
this AD by the following condition:
(1) A special flight permit to fly the airplane to where the
visual inspection can be done may be issued after the operator
verifies that the turbocharger tailpipe assembly is secure.
(2) To verify, apply a side load and a vertical load to the
tailpipe assembly by hand. No mechanical deflection is allowed.
(3) After verifying that the tailpipe assembly is secure, the
operator can apply for a special flight permit from the FAA. The FAA
office or person approving the permit must add this condition to the
limitations of the special flight permit.
Previous Credit
(n) If you used Kelly Aerospace Power Systems MSB No. 030, dated
February 15, 2008 before the effective date of this AD to identify
the suspect population of turbochargers identified in applicability
paragraphs (c)(2) through (c)(9) of this AD, you satisfied the
requirements of those paragraphs in this AD.
