[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 adopt a new 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. This proposed AD would
require replacing these ECi cylinder assemblies. This proposed AD
results from reports of about 30 failures of the subject cylinder
assemblies marketed by ECi. 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 November 8,
2005.
ADDRESSES: Use one of the following addresses to comment on this
proposed AD.

Discussion
We received reports of about 30 failures of ECi cylinder
assemblies, P/N AEL65102 series, with casting P/N AEL65099, installed
on Lycoming Engines models 320, 360, and 540 series, parallel valve
reciprocating engines. Parallel valve Lycoming reciprocating engines
are identified by the intake and exhaust valves in a parallel
configuration. We investigated the failures and discovered that
cylinder head fatigue cracks start in the thin wall located between the
counter-bore of the exhaust valve seat and adjacent cooling fin root.
Our investigation concluded that the wall thickness of the affected
area is too thin, making the wall vulnerable to fatigue cracking. Our
investigation also concluded that the fatigue origin is not associated
with surface damage resulting from cylinder head over-temperature
conditions. Based on these findings, we issued Special Airworthiness
Information Bulletin (SAIB) No. NE-01-32, dated July 18, 2001, to alert
owners and operators to visually inspect, and to report and replace ECi
cylinder heads if found cracked.
As a result of our investigation and issuing SAIB No. NE-01-32, ECi
introduced an improved cylinder head design for casting P/N AEL65099,
starting with serial number (SN) 9880. Their design change increased
the cylinder head exhaust port wall thickness. Since the issuance of
the SAIB, we continue to receive reports of cracking of ECi cylinder
assemblies with casting P/N AEL65099, SNs 1 through 9879. The most
recent report, from Kenya, described three cylinders showing cracks,
with two of the cylinders separating from the barrel. This condition,
if not corrected, could result in loss of engine power due to cracks in
the cylinder assembly and possible engine failure caused by separation
of a cylinder head. This proposed AD only applies to ECi ``Classic
Cast'' cylinder assemblies identified with casting P/N AEL65099 and SNs
1 through 9879.
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 the following:
Determine if ECi cylinder assemblies, P/N AEL65102 series
``Classic Cast'', with casting P/N AEL65099 and SN 1 through 9879 are
installed on your engine; and
If any cylinder assembly is an ECi P/N AEL65102 series
``Classic Cast'', with casting P/N AEL65099 and a SN 1 through 9879,
and has fewer than 800 operating hours-in-service (HIS) on the
effective date of the proposed AD, replace the cylinder assembly at no
later than 800 operating HIS. No action is required until the operating
HIS reaches 800 hours.
If any cylinder assembly is an ECi P/N AEL65102 series
``Classic Cast'', with casting P/N AEL65099 and a SN 1 through 9879,
and has 800 operating HIS or more on the effective date of the proposed
AD, replace the cylinder assembly within 60 operating HIS after the
effective date of the proposed AD.
After the effective date of the proposed AD, do not
install any ECi cylinder assembly, P/N AEL65102, with casting P/N
AEL65099 that has a SN 1 through 9879, onto any engine.
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 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.

Unsafe Condition
(d) This AD results from reports of approximately 30 failures of
the subject cylinder assemblies marketed by ECi. 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 Repaired or Overhauled 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,'' with casting P/N AEL65099 and SNs 1 through 9879
are installed on your engine, as follows:
(i) Inspect the engine log books and maintenance records for
reference to the subject ECi cylinder assemblies.
[[Page 53594]]
(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'', with casting P/N AEL65099, no further action is
required.
(3) If any cylinder assembly is an ECi P/N AEL65102 series
``Classic Cast,'' with casting P/N AEL65099 and a SN 1 through 9879,
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.
Definition of a Replacement Cylinder Assembly
(h) For the purpose of this AD, a replacement cylinder assembly
is defined as follows:
(1) A serviceable cylinder assembly made by Lycoming Engines.
(2) A serviceable FAA-approved, Parts Manufacturer Approval
cylinder assembly from another manufacturer.
(3) A serviceable ECi cylinder assembly, P/N AEL65102 series,
``Titan,'' with casting P/N AEL85009.
(4) A serviceable ECi cylinder assembly, P/N AEL65102 series,
with casting, P/N AEL65099, that has a SN 9880 or higher.
Prohibition of Cylinder Assemblies, P/N AEL65102 Series ``Classic
Cast,'' With Casting P/N AEL65099 and SNs 1 Through 9879
(i) After the effective date of this AD, do not install any ECi
cylinder assembly, P/N AEL65102, with casting P/N AEL65099 that has
a SN 1 through 9879, onto any engine.
Alternative Methods of Compliance
(j) The Manager, Special 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.
Issued in Burlington, Massachusetts, on September 2, 2005.
