ACTION: Final rule. AGENCY: 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 https:// www.Lycoming.Textron.com. You may examine the AD docket on the Internet at https://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 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 (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: Type of application Constant-Speed Propeller ........ Fixed-Pitch Propeller ............. Work-hours per engine Number of engines affected 86 251 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 E:\FR\FM\23MRR1.SGM 23MRR1 Federal Register / Vol. 71, No. 56 / Thursday, March 23, 2006 / Rules and Regulations 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.

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 https://

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.
