14 CFR Part 39

[Docket No. FAA-2005-22358; Directorate Identifier 2005-NE-20-AD; 
Amendment 39-14632; AD 2006-12-07]
RIN 2120-AA64


Airworthiness Directives; Engine Components Inc. (ECi) 
Reciprocating Engine Cylinder Assemblies

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Lycoming Engines (formerly Textron Lycoming) models 320, 360, 
and 540 series, ``Parallel Valve'' reciprocating engines, with certain 
Engine Components Inc. (ECi) cylinder assemblies, part number (P/N) 
AEL65102 series ``Classic Cast'', installed. That AD currently requires 
replacing these ECi cylinder assemblies. This AD requires the same 
actions, but replaces the ``Engine Models'' Table 1 and ``Engines 
Installed On, But Not Limited To'' Table 2 with corrected tables. Also, 
this AD corrects the casting part number. This AD results from reports 
of applicability errors found in AD 2005-26-10. We are issuing this AD 
to prevent loss of engine power due to cracks in the cylinder 
assemblies and possible engine failure caused by separation of a 
cylinder head.

DATES: This AD becomes effective July 11, 2006.

ADDRESSES: 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: Peter Hakala, Aerospace Engineer, 
Special Certification Office, FAA, Rotorcraft Directorate, 2601 Meacham 
Blvd., Fort Worth, TX 76193; telephone (817) 222-5145; fax (817) 222-
5785.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to Lycoming Engines models 
320, 360, and 540 series, ``Parallel Valve'' reciprocating engines, 
with certain ECi cylinder assemblies, P/N AEL65102 series ``Classic 
Cast'', installed. We published the proposed AD in the Federal Register 
on February 24, 2006 (71 FR 9480). That action proposed to require the 
same actions as AD 2005-26-10, but would replace the

[[Page 32428]]

``Engine Models'' Table 1 and ``Engines Installed On, But Not Limited 
To'' Table 2 with corrected tables. Also, that action proposed to 
correct the casting part number.

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 Office 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.

Request To Change All References to Casting P/N AEL65099

    One commenter requests that we change all references to casting P/N 
AEL65099 to read ``casting head markings EC 65099-REV-1'' to more 
accurately describe the actual markings. We agree, and made the 
reference changes in the AD.

Request To Explain Another Set of Numbers on the Cylinder

    The same commenter requests that we explain that the set of numbers 
appearing on the cylinder below and to the left of the SN, in the form 
of ``12345-67'' is not used for determining applicability. We agree, 
and have added a statement to point this out in the AD.

Update to Related Information

    Under paragraph (k), Related Information, we updated the reference 
to ECi Service Bulletin No. 05-08, Revision 1, dated December 29, 2005, 
to Revision 2, dated February 28, 2006.

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 with the changes described previously. 
We have determined that these changes will neither increase the 
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    We estimate that 7,557 ECi cylinder assemblies are installed on 
Lycoming engines in the United States. We estimate that it will take 
about two workhours per engine to perform the aircraft inspections of 
the cylinder assemblies for applicability, and that the average labor 
rate is $65 per workhour. From the Lycoming Engines ``Removal and 
Installation Labor Allowance Guidebook'', dated May 2000, the complete 
cylinder replacement for a four cylinder engine takes 12 hours, while 
the complete cylinder replacement for a six cylinder engine takes 16 
hours. Required parts will cost about $1,000 per cylinder assembly. 
Based on these figures, we estimate that the total cost of the AD to 
U.S. operators to be $9,152,140. ECi indicated that they might give 
operators and repair stations credit for returned cylinder assemblies 
toward the purchase of new ECi cylinder assemblies.

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;
    (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 reports of applicability errors found 
in AD 2005-26-10. We are issuing this AD to prevent loss of engine 
power due to cracks in the cylinder assemblies and possible engine 
failure caused by separation of a cylinder head.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified unless the 
actions have already been done.

Engines Not Overhauled or Repaired Since New

    (f) If your engine has not been overhauled or had any major 
repair since new, no further action is required.

Engines Overhauled or Repaired Since New

    (g) If your engine was overhauled or repaired since new, do the 
following:
    (1) Determine if ECi cylinder assemblies, P/N AEL65102 series 
``Classic Cast'', having casting head markings EC 65099-REV-1 and 
SNs 1 through 9879 (SN may have an ``L'' prefix for a long reach 
spark plug) are installed on your engine, as follows:
    (i) Inspect the engine log books and maintenance records for 
reference to the subject ECi cylinder assemblies.
    (ii) If the engine log books and maintenance records did not 
record the P/N and SN of the cylinder assemblies, visually inspect 
the cylinder assemblies and verify the P/N and SN of the cylinder 
assemblies.
    (2) If the cylinder assemblies are not ECi, P/N AEL65102 series 
``Classic Cast'', having casting head markings EC 65099-REV-1, no 
further action is required.
    (3) If any cylinder assembly is an ECi P/N AEL65102 series 
``Classic Cast'', having casting head markings EC 65099-REV-1 and a 
SN 1 through 9879 (SN may have an ``L'' prefix for a long reach 
spark plug), do the following:
    (i) If the cylinder assembly has fewer than 800 operating hours-
in-service (HIS) on the effective date of this AD, replace the 
cylinder assembly at no later than 800 operating HIS. No action is 
required until the operating HIS reaches 800 hours.
    (ii) If the cylinder assembly has 800 operating HIS or more on 
the effective date of this AD, replace the cylinder assembly within 
60 operating HIS after the effective date of this AD.
