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 superseding airworthiness directive (AD) 2012-24-09 for 
Lycoming Engines TIO-540-AK1A, and Continental Motors, Inc. (CMI) TSIO-
360-MB, TSIO-360-SB, and TSIO-360-RB reciprocating engines, with 
certain Hartzell Engine Technologies (HET) turbochargers, model TA0411, 
installed. AD 2012-24-09 required removing certain HET turbochargers 
from service before further flight. This AD also requires removing 
certain HET turbochargers from service before further flight. This AD 
was prompted by a report that an additional engine, the CMI LTSIO-360-
RB, has the affected HET turbochargers installed. 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 November 13, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 20, 
2012 (77 FR 72203, December 5, 2012).
    We must receive any comments on this AD by December 13, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    On November 29, 2012, we issued AD 2012-24-09, Amendment 39-17279 
(77 FR 72203, December 5, 2012), for Lycoming Engines TSIO-540-AK1A, 
and CMI TSIO-360-MB, TSIO-360-SB, and TSIO-360-RB reciprocating 
engines, with certain HET turbochargers, model TA0411, part numbers 
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. On January 7, 2013, we issued a 
correction to AD 2012-24-09 (78 FR 2615, January 14, 2013), which 
corrected the affected Lycoming Engines engine model from ``TSIO-540-
AK1A'' to ``TIO-540-AK1A.'' AD 2012-24-09 required removing the 
affected turbochargers from service before further flight. AD 2012-24-
09 resulted from a report of a turbocharger turbine wheel that failed a 
static strength test at the manufacturing facility. We issued AD 2012-
24-09 to prevent turbocharger turbine wheel failure, reduction or 
complete loss of engine power, loss of engine oil, oil fire, and damage 
to the airplane.

Actions Since AD 2012-24-09 Was Issued

    Since we issued AD 2012-24-09 (77 FR 72203, December 5, 2012; 
corrected January 14, 2013 (78 FR 2615)), we received a report that an 
additional engine, the CMI LTSIO-360-RB, has the affected HET 
turbochargers installed.

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 the 
AD requires removal of the affected turbochargers before further 
flight. 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 we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. 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 
``Docket No. FAA-2012-1245; 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 engines 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 this 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 to the extent 
that it justifies making a regulatory distinction, 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.

Packet generated 2026-08-18 08:53 UTC.

This packet is not an airworthiness determination and not legal or maintenance advice. AircraftDirectives reproduces official records and condenses their wording for easier reading. It does not decide, certify or imply whether any aircraft, engine, appliance or part is airworthy, compliant, affected by this directive, or eligible for return to service. No inspection, approval, or determination of any kind is performed or implied by this document.

Section 1 is a reading aid, not the rule. It is our own plain-language condensation, written to help a reader find the relevant directive quickly. It is NOT a substitute for the regulation, it may omit conditions, exceptions, compliance times, alternative methods of compliance (AMOCs) and applicability limits, and it has no legal force whatsoever. Only the official text governs. Where Section 1 and Section 2 differ in any respect, Section 2 - and the official source it was retrieved from - controls absolutely.

Responsibility remains with the owner/operator. Under 14 CFR §91.403 and §91.417 the owner or operator is responsible for maintaining airworthiness and for required records; under §39.7 no person may operate a product to which an airworthiness directive applies except in accordance with that directive. Determining applicability to a specific serial number and configuration, and performing or supervising any required action, is the responsibility of the owner/operator and appropriately certificated personnel.

Accuracy and currency. Section 2 was retrieved at the time stamped above and is reproduced without edit; Federal Register material is a work of the United States Government. Directives are amended, corrected and superseded over time, and this sheet is a snapshot, not a live record - it does not update after printing. Re-check the official sources before acting on it. This packet is provided without warranty of any kind, express or implied, including fitness for a particular purpose. We do not sell parts and have no commercial interest in any action a directive may require.
