14 CFR Part 39
[Docket No. FAA-2005-23269; Directorate Identifier 2005-NE-50-AD]
RIN 2120-AA64
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: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt 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
proposed AD would require replacing certain crankshafts. This proposed
AD results from a report of a crankshaft failure in a Lycoming LO-360-
A1H6 reciprocating engine. We are proposing 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: We must receive any comments on this proposed AD by January 26,
2006.
ADDRESSES: Use one of the following addresses to comment on this
proposed AD.

Discussion
On September 9, 2005, we issued AD 2005-19-11, Amendment 39-14276
(70 FR 54618) applicable to 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. That AD
requires replacing certain crankshafts within 50 hours time-in-service
or 6 months after the effective date of the AD, whichever is earlier.
Airworthiness directive 2005-19-11 resulted from 12 reports of
crankshaft failures on engines rated at 300 HP or lower. Our
investigation into the crankshaft failures found that the failures
result from subsurface metallurgical flaws, caused by lack of
crankshaft process control. While this proposed AD would affect
different crankshafts than those affected by AD 2005-19-11, the
crankshafts have the same possible unsafe condition. This proposed AD
results from a report of a crankshaft failure in a Lycoming LO-360-A1H6
engine. This proposed AD would require replacing certain crankshafts
installed in engines manufactured new or rebuilt, overhauled, or that
had a crankshaft replaced after March 1, 1999. This condition, if not
corrected, could result in crankshaft failure, which could result in
total engine power loss, in-flight engine failure, and possible loss of
the aircraft. The engines and crankshafts affected by this proposed AD
are listed by serial number (SN) in Table 1 and Table 2 of Lycoming
Engines Supplement No.1 to Mandatory Service Bulletin (MSB) No. 566.
These engine and crankshaft SNs are different from the engine and
crankshaft SNs affected by Lycoming Engines MSB No. 552, No.
[[Page 76432]]
553, and No. 566; and ADs 2002-19-03 and 2005-19-11.
Relevant Service Information
We have reviewed and approved the technical contents of Lycoming
Engines Supplement No. 1 to Mandatory Service Bulletin No. 566, dated
November 30, 2005, that describes procedures for replacing crankshafts
listed by SN in that Supplement.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other products
of this same type design. We are proposing this AD, which would require
replacing certain crankshafts within 50 hours time-in-service or 6
months after the effective date of the proposed AD, whichever is
earlier. The proposed AD would require you to use the service
information described previously to perform these actions.
Costs of Compliance
We estimate that this proposed AD would affect 282 engines
installed on aircraft of U.S. registry. We estimate that it would 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 would cost about $15,300. Based on these
figures, we estimate the total cost of the proposed 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 proposed 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. Would 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 regulatory evaluation of the estimated costs to
comply with this proposed AD. See the ADDRESSES section for a location
to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39

------------------------------------------------------------------------
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.
