Airworthiness Directives; Lycoming Engines and Continental 
Motors, Inc. Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for 
Lycoming Engines TSIO-540-AK1A, and Continental Motors, Inc. TSIO-360-
MB, TSIO-360-SB, and TSIO-360-RB reciprocating engines, with certain 
Hartzell Engine Technologies (HET) turbochargers, model TA0411, part 
number (P/N) 466642-0001; 466642-0002; 466642-0006; 466642-9001; 
466642-9002; or 466642-9006, or with certain HET model TA0411 
turbochargers overhauled or repaired since August 29, 2012. This AD 
requires removing the affected turbochargers from service before 
further flight. This AD was prompted by a report of a turbocharger 
turbine wheel that failed a static strength test at its manufacturing 
facility. We are issuing this AD to prevent turbocharger turbine wheel 
failure, reduction or complete loss of engine power, loss of engine 
oil, oil fire, and damage to the airplane.

DATES: This AD is effective December 20, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 20, 
2012.
    We must receive comments on this AD by January 22, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    We received a report of an HET turbocharger turbine wheel that 
failed a static strength test at its manufacturing facility. Subsequent 
tests showed that nearly all turbine wheels, P/N 410188-0019, had 
significant cracking under the surface of a critical weld joint between 
the turbine wheel head and shaft that occurred during manufacturing. 
HET has identified by serial number (S/N) the turbochargers shipped 
from the factory with this unsafe condition. HET has also identified 
the S/N range of affected turbine wheels. Some of the affected turbine 
wheels became available for overhaul or field repair since August 29, 
2012, and may have been installed. This condition, if not corrected, 
could result in turbocharger turbine wheel failure, reduction or 
complete loss of engine power, loss of engine oil, oil fire, and damage 
to the airplane.

Relevant Service Information

    We reviewed HET Alert Service Bulletin (ASB) No. 048, dated 
November 16, 2012. The ASB lists the known serial numbers of affected 
turbochargers.

[[Page 72204]]

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

AD Requirements

    This AD requires removing the affected turbochargers from service 
before further flight.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because HET 
cannot confirm the affected turbochargers can safely be used. 
Therefore, we find that notice and opportunity for prior public comment 
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 any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2012-1245 and 
Directorate Identifier 2012-NE-41-AD at the beginning of your comments. 
We specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    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 we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 56 airplanes of U.S. registry with 
affected turbochargers installed. We also estimate that it will take 
about 4 hours to remove a turbocharger from service. The average labor 
rate is $85 per hour. Based on these figures, we estimate the total 
cost of the AD to U.S. operators to be $19,040.

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

    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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
