ACTION: Final rule; request for comments. AGENCY: 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 undercowl 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 inflight 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 E:\FR\FM\21APR1.SGM 21APR1 Federal Register / Vol. 73, No. 77 / Monday, April 21, 2008 / Rules and Regulations 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 inflight 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. rfrederick on PROD1PC67 with RULES 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.

Adoption of the Amendment Under the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: Authority for This Rulemaking I 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.

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.

ACTION: Final rule. AGENCY: rfrederick on PROD1PC67 with RULES SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Wing anti ice telescopic tubes (P/N [part number] 5035–400 and 5035–500) ball joints were originally designed with high temperature polymer (KynelTM) sealing rings. Temperature induced cracking of these rings associated with long term wear has been encountered in a small number of cases. This degradation may lead to binding of the ball joint and high swiveling forces which may result in improper operation of the leading edge slats and also in failure of the ball joint mounting bracket with possible friction on the aileron control rod, which could lead, if combined with a failure of the aileron emergency actuator, to an aileron jamming. The unsafe condition is a jammed aileron, which results in reduced controllability of the airplane.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 27, 2008. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC. FOR FURTHER INFORMATION CONTACT: Tom Rodriguez, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057–3356; telephone (425) 227–1137; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on February 5, 2008 (73 FR 6618). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Wing anti ice telescopic tubes (P/N [part number] 5035–400 and 5035–500) ball joints were originally designed with high temperature polymer (KynelTM) sealing rings. Temperature induced cracking of these rings associated with long term wear has been encountered in a small number of cases. This degradation may lead to binding of the ball joint and high swiveling forces which may result in improper operation of the leading edge slats and also in failure of the ball joint mounting bracket with possible friction on the aileron control rod, which could lead, if combined with a failure of the aileron emergency actuator, to an aileron jamming. A replacement carbon based material has been defined by the telescopic tube manufacturer ZODIAC and can be applied per ZODIAC Service Bulletins (SB) 5035–30– 001 and 5035–30–002, resulting in P/N redesignations 5035–600 Amdt.A and 5035– 700 Amdt.A, respectively. PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 Date The purpose of this Airworthiness Directive (AD), by requiring modification of the wing anti-ice telescopic tubes in accordance with the ZODIAC service bulletins, is to ensure that no old definition sealing rings remain in operation beyond a life limit of 2,400 flight hours (FH) or 2,000 flight cycles (FC). The unsafe condition is a jammed aileron, which results in reduced controllability of the airplane. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD.

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 https://
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 https://
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.
