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.
You may examine the AD docket on the Internet at http://dms.dot.gov
or in Room PL-401 on the plaza level of the Nassif Building, 400
Seventh Street, SW., Washington, DC.

York Aircraft Certification Office, FAA, Engine & Propeller
Directorate, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590;
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.
