14 CFR Part 39

[Docket No. FAA-2005-22358; Directorate Identifier 2005-NE-20-AD]
RIN 2120-AA64


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

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede 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 
proposed AD would require the same actions, but would replace the 
``Engine Models'' Table 1 and ``Engines Installed On, But Not Limited 
To'' Table 2 with corrected tables. Also, this proposed AD would 
correct a casting part number. This proposed AD results from reports of 
applicability errors found in AD 2005-26-10. We are proposing 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: We must receive any comments on this proposed AD by March 13, 
2006.

ADDRESSES: Use one of the following addresses to comment on this 
proposed AD.

Discussion

    On December 19, 2005, we issued AD 2005-26-10, Amendment 39-14431 
(70 FR 76385, December 27, 2005). That AD requires replacing ECi 
cylinder assemblies P/N AEL65102 series ``Classic Cast'', having 
casting P/N AEL65099 and SN 1 through 9879. That AD was the result of 
reports of about 30 failures of the subject cylinder assemblies 
marketed by ECi. That condition, if not corrected, could result in loss 
of engine power due to cracks in the cylinder assemblies and possible 
engine failure caused by separation of a cylinder head.

Actions Since AD 2005-26-10 was Issued

    Since AD 2005-26-10 was issued, we received reports of errors in 
the ``Engine Models'' Table 1, and ``Engines Installed On, But Not 
Limited To'' Table 2. Also, we discovered an incorrect part number in 
paragraph (h)(3).

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. For that reason, we are proposing this AD to 
ensure that operators are provided with the correct applicability, 
which would require:
     Replacing ECi cylinder assemblies P/N AEL65102 series 
``Classic Cast'', having casting P/N AEL65099 and SN 1 through 9879 
(sold from January 1997 to September 2001); (same as AD 2005-26-10);
     Replacing the ``Engine Models'' Table 1 with a corrected 
Table 1, to ensure that operators are provided with the correct 
applicability; and
     Replacing the ``Engines Installed On, But Not Limited To'' 
Table 2 with a corrected Table 2; and
     Replacing casting P/N AEL85009 with P/N AEL85099 in 
paragraph (h)(3),

[[Page 9481]]

``Definition of a Replacement Cylinder Assembly''.

Costs of Compliance

    There were 9,879 ECi cylinder assemblies produced of the affected 
design available to the worldwide fleet. ECi reported that about 
fifteen percent of their cylinder assemblies go to foreign countries. 
We estimate ten percent of the remaining cylinders were never installed 
or are already removed from service, leaving 7,557 cylinder assemblies 
in service in the United States. We estimate that 1,574 Lycoming 
engines are in the United States with the subject cylinder assemblies 
installed. We estimate that it would take about two work hours per 
engine to perform the proposed aircraft inspections of the cylinder 
assemblies for applicability, and that the average labor rate is $65 
per work hour. 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 would cost about $1,000 per cylinder assembly. Based on 
these figures, we estimate that the total cost of the proposed 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 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.

    (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:
