14 CFR Part 39
[Docket No. FAA-2005-23269; Directorate Identifier 2005-NE-50-AD;
Amendment 39-14525; AD 2006-06-16]

Airworthiness Directives; Lycoming Engines (Formerly Textron
Lycoming) AEIO-360, IO-360, O-360, LIO-360, and LO-360 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, and LO-360 series reciprocating engines. This AD
requires replacing certain crankshafts. This AD results from a
crankshaft failure in a Lycoming LO-360-A1H6 reciprocating engine. 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 April 27, 2006. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of April 27, 2006.
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.
FOR FURTHER INFORMATION CONTACT: Norm Perenson, Aerospace Engineer, New
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 AD. The proposed AD applies to certain Lycoming Engines
(formerly Textron Lycoming) AEIO-360, IO-360, O-360, LIO-360, and LO-
360 series reciprocating engines. We published the proposed AD in the
Federal Register on December 27, 2005 (70 FR 76431). That action
proposed to require replacing certain crankshafts within 50 hours time-
in-service or 6 months after the effective date of this 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 received no comments on the proposal or on
the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data 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 282 engines installed on
aircraft of U.S. registry. We estimate that it will take the following
work hours to perform the inspection and crankshaft replacement:
------------------------------------------------------------------------
Number of
Type of application Work-hours engines
per engine affected
------------------------------------------------------------------------
Constant-Speed Propeller...................... 86 251
Fixed-Pitch Propeller......................... 84.5 31
------------------------------------------------------------------------
We estimate the average labor rate is $65 per work hour and that
required parts for each engine will cost about $15,300. Based on these
figures, we estimate the total cost of the AD to U.S. operators to be
$5,887,957. Lycoming Engines informed us that they intend to supply the
new parts at no charge and reimburse labor costs when authorized, for
engine removal and reinstallation, using the current revision of
Lycoming's Removal and Installation Labor Allowance Guidebook. These
actions would 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
[[Page 14639]]
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 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 a crankshaft failure in a Lycoming LO-
360-A1H6 reciprocating engine. 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.
Compliance
(e) You are responsible for having the actions required by this
AD performed within 50 hours time-in-service or 6 months after the
effective date of this AD, whichever is earlier, unless the actions
have already been done.
(f) If Lycoming Engines manufactured new, rebuilt, overhauled,
or replaced the crankshaft in your engine before March 1, 1999, and
you haven't had the crankshaft replaced, no further action is
required.
(g) If Table 1 of Supplement No. 1 to Lycoming Mandatory Service
Bulletin (MSB) No. 566, dated November 30, 2005, lists your engine
serial number (SN), use Table 2 of Supplement No. 1 to verify if
your crankshaft SN is listed.
(h) If Table 1 of Supplement No. 1 to Lycoming MSB No. 566,
dated November 30, 2005, does not list your engine SN, use Table 2
of Supplement No. 1 to verify if your crankshaft SN is listed, if an
affected crankshaft was installed as a replacement.
(i) If Table 2 of Supplement No. 1 to Lycoming Engines MSB No.
566, dated November 30, 2005, lists your crankshaft SN, replace the
crankshaft with a crankshaft that is not listed in Table 2 of
Supplement No. 1 to Lycoming MSB No. 566, dated July 11, 2005.
(j) The engine and crankshaft SNs listed in Table 1 and Table 2
of Supplement No.1 to Lycoming Engines MSB No. 566 are different
from the engine and crankshaft SNs affected by Lycoming MSBs No.
552, No. 553 and No. 566; and ADs 2002-19-03 and 2005-19-11.
Prohibition Against Installing Certain Crankshafts
(k) After the effective date of this AD, do not install any
crankshaft that has a SN listed in Table 2 of Supplement No. 1 to
Lycoming MSB No. 566, dated November 30, 2005, into any engine.
Alternative Methods of Compliance
(l) The Manager, New York 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.
Related Information
(m) None.
