[Docket No. FAA-2005-21864; Directorate Identifier 2005-NE-29-AD; 
Amendment 39-14276; AD 2005-19-11]

Airworthiness Directives; Lycoming Engines (Formerly Textron 
Lycoming) AEIO-360, IO-360, O-360, LIO-360, LO-360, AEIO-540, IO-540, 
O-540, and TIO-540 Series Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Lycoming Engines (formerly Textron Lycoming) AEIO-360, IO-360, 
O-360, LIO-360, LO-360, AEIO-540, IO-540, O-540, and TIO-540 series 
reciprocating engines rated at 300 horsepower (HP) or lower. This AD 
requires replacing certain crankshafts. This AD results from reports of 
12 crankshaft failures in Lycoming 360 and 540 series engines rated at 
300 HP or lower. We are issuing this AD to prevent failure of the 
crankshaft, which could result in total engine power loss, in-flight 
engine failure, and possible loss of the aircraft.

DATES: This AD becomes effective October 21, 2005. The Director of the 
Federal Register approved the incorporation by reference of certain

[[Page 54619]]

publications listed in the regulations as of October 21, 2005.

ADDRESSES: You can get the service information identified in this AD 
from Lycoming, 652 Oliver Street, Williamsport, PA 17701; telephone 
(570) 323-6181; fax (570) 327-7101, or on the Internet at http://www.Lycoming.Textron.com.

telephone (516) 228-7337; fax (516) 794-5531.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed airworthiness directive (AD). The proposed AD applies 
to Lycoming Engines (formerly Textron Lycoming) AEIO-360, IO-360, O-
360, LIO-360, LO-360, AEIO-540, IO-540, O-540, and TIO-540 series 
reciprocating engines rated at 300 horsepower (HP) or lower. We 
published the proposed AD in the Federal Register on July 22, 2005 (70 
FR 42282). That action proposed to require replacing certain 
crankshafts within 50 hours time-in-service or 6 months after the 
effective date of the proposed AD, whichever is earlier.

Examining the AD Docket

    You may examine the docket that contains the AD, any comments 
received, and any final disposition in person at the Docket Management 
Facility Docket Offices between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The Docket Office (telephone (800) 
647-5227) is located on the plaza level of the Department of 
Transportation Nassif Building at the street address stated in 
ADDRESSES. Comments will be available in the AD docket shortly after 
the DMS receives them.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Will Additional Engines and Crankshafts Be Affected in the Future

    One commenter asks if additional serial numbered engines and 
crankshafts will be affected in the future.
    At this time we do not anticipate that the affected population will 
increase, but Lycoming and the FAA are monitoring crankshaft 
performance.

Affected Engines and Crankshafts

    The same commenter asks why these engines and crankshafts are the 
only ones affected by the SB and AD.
    Both the previous AD (2002-19-03) and this AD advise that the 
affected population of engines and crankshafts were manufactured in a 
specific time period. We are addressing that time period.

Suspect Crankshafts Should Be Either Tested or Replaced

    One commenter states that suspect crankshafts should be either 
tested or replaced before further flight, because the problem with 
these crankshafts is similar to the problem that caused the crankshaft 
failures on the 540 engines.
    We disagree. The compliance interval in this AD is based on an 
assessment of operating stresses, service experience, and duty cycle of 
the affected engine population. The compliance interval differs from 
that imposed in AD 2002-19-03 due to differences in these parameters.

Request To Include Lycoming TIO-540-AE2A and Other Unspecified Engine 
Models

    One commenter requests that we include the Lycoming TIO-540-AE2A 
and other unspecified engine models in this AD. The commenter states 
that many of the TIO-540-AE2A engines have never been recalled or 
replaced yet should be, because recent litigation has shown that 
Lycoming's crankshaft end core sample test is insufficient.
    We disagree. We have seen no evidence that refutes the validity of 
the test. Further, AD 2002-19-03 (the previous AD) effective on 
September 20, 2002, described two groups of crankshafts. We required 
one crankshaft group to be removed before further flight, and we 
required the other crankshaft group to have a sample of the crankshaft 
material tested. The crankshafts in each group were selected based on 
our evaluation of the risk both groups presented. Crankshafts from 
either group may be installed in the TIO-540-AE2A engine model. No 
failures of crankshafts listed in either group have occurred since.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD as proposed.

Costs of Compliance

    We estimate that this AD will affect 1,128 engines installed on 
aircraft of U.S. registry. We estimate that it will take the following 
work hours to perform the inspection:

------------------------------------------------------------------------
                                                              Number of
             Type of  application               Work-hours     engines
                                                per engine     affected
------------------------------------------------------------------------
Helicopter...................................          12            200
Constant-Speed Propeller.....................           3            557
Fixed-Pitch Propeller........................           1.5          371
------------------------------------------------------------------------

    We also estimate that it will take about 33 work hours to replace 
the crankshaft. We estimate the average labor rate is $65 per work hour 
and that required parts for each engine will cost about $16,218. Based 
on these figures, we estimate the total cost of the AD to U.S. 
operators to be $18,594,724. Lycoming Engines informed us that they 
intend to supply the new parts at no charge, which may substantially 
reduce the estimated cost of this AD.

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;

[[Page 54620]]

    (2) Is not a ``significant rule'' under 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.
