DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2008-0052; Directorate Identifier 2008-NE-01-AD;
Amendment 39-15672; AD 2008-19-05]
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 adopting 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 ``Titan'', installed. This AD requires initial and repetitive
visual inspections and compression tests to detect cracks at the head-
to-barrel interface, replacement of cylinder assemblies found cracked,
and replacement of certain cylinder assemblies, at new reduced times-
in-service. This AD results from reports of 45 failures with head
separations of ECi cylinder assemblies. We are issuing this AD to
prevent loss of engine power due to cracks at the head-to-barrel
interface in the cylinder assemblies and possible engine failure caused
by separation of a cylinder head, which could result in loss of control
of the aircraft.
DATES: This AD becomes effective October 20, 2008.
ADDRESSES: You can get the service information identified in this AD
from Engine Components, Inc., 9503 Middlex, San Antonio, TX 78217;

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed AD. The proposed AD applies to 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 ``Titan'',
installed. We published the proposed AD in the Federal Register on May
19, 2008 (73 FR 28756). That action proposed to require initial and
repetitive visual inspections and compression tests to detect cracks at
the head-to-barrel interface, replacement of cylinder assemblies found
cracked, and replacement of certain cylinder assemblies, at new reduced
times-in-service.
Examining the AD Docket
You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is provided in
the ADDRESSES section. Comments will be available in the AD docket
shortly after receipt.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Reduce the Economic Impact
One commenter, the Aircraft Owners and Pilots Association, states
that the 50-hour inspection interval should be increased to 100 hours,
to reduce the economic impact of the cylinder assembly inspections.
Another commenter, a private citizen, states that the cost of the 50-
hour inspections was not considered in the NPRM economic estimate.
We do not agree. We selected the 50-hour inspection interval so
that aluminum cylinder cracks could be detected before a head
separation occurred. By removing leaking cylinder heads discovered
during the periodic 50-hour inspections, the probability of having an
in flight head separation is greatly reduced. Also, the 50-hour
inspection interval coincides with the scheduled maintenance for normal
engine oil and filter changes. Also, the costs of compliance in the
NPRM did include costs for the additional cylinder assembly
inspections. We did not change the AD.
Retiring Cylinder Assemblies at Time-Between-Overhaul Is Too Expensive
One commenter, a private citizen, states that it is too expensive
to retire all the subject cylinder assemblies at the normal overhaul
time. Another commenter, a private citizen, states that it is
unreasonable for general aviation airplane owners, in Part 91 use, to
be required to retire cylinder assemblies at the time-between-overhaul
or at normal engine overhaul time.
We do not agree. The subject cylinder assemblies can be safely run
to the normal TBO with the required 50-hour inspections, with
compression tests. Because of metallurgical analysis results of the
fatigue cracks in the aluminum alloy cylinder heads, and also the
history of the head separation hours-in-service, the probability of a
head separation is greater with the subject cylinder assemblies running
past the time-between-overhaul time. Therefore, we do not consider the
cylinder assemblies to be airworthy past the normal engine overhaul
time. We did not change the AD.
[[Page 53106]]
Cylinder Assembly Serial Number Range Is Different in the ECi Mandatory
Service Bulletin
One commenter, ECi., states that the cylinder assembly serial
number range in the proposed AD for the Group ``B'' cylinders is
slightly different from the serial numbers listed in the ECi Mandatory
service Bulletin No. 08-1. The commenter states that several additional
cylinder serial numbers should be included in Group ``B''.
We do not agree. We researched the cylinder assembly serial numbers
in the proposed AD and they are correct. The Group ``A'' cylinder
assemblies go up to serial number 35171-22. The Group ``B'' cylinder
assemblies start at serial number 35239-01. We discussed the serial
number comment with ECi. They agree that the serial number range in the
proposed AD is correct. ECi states that they have revised the serial
numbers in ECi. Mandatory Service Bulletin (MSB) No. 08-1 to match the
serial numbers in the AD, and issued MSB No. 08-1, Revision 3, dated
August 19, 2008. We now reference this MSB Revision 3 in the AD.
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 as proposed. 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 this AD will affect 13,000 ECi cylinder assemblies
installed in aircraft of U.S. registry. The visual inspection and
compression tests will take about 4 work-hours for each engine. An
individual cylinder replacement will require $1,100 for parts and 6
work-hours. Lycoming engines with a set of 4 ECi cylinders will require
12 work-hours for the cylinder replacement. Lycoming engines with a set
of 6 ECi cylinders will require 16 work-hours for the cylinder
replacement. We estimate 18 percent of the affected population of
cylinders will be replaced. We estimate the total cost of the AD to
U.S. operators to be $7,952,000. Our estimate is exclusive of any
possible warranty coverage.
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.

Air transportation, Aircraft, Aviation safety, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the Federal Aviation Administration amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2008-19-05 Engine Components, Inc. (ECi): Amendment 39-15672. Docket
No. FAA-2008-0052; Directorate Identifier 2008-NE-01-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective October
20, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the Lycoming Engines (formerly Textron
Lycoming) models 320, 360, and 540 series, ``Parallel Valve'',
reciprocating engines listed in Table 1 of this AD, with ECi
cylinder assembly, part number (P/N) AEL65102 series ``Titan'', and
with cylinder head, P/N AEL85099, installed.
(1) The applicable cylinder assembly serial numbers (SNs) are SN
1138-02 through SN 35171-22, (referred to in this AD as Group ``A''
cylinder assemblies); and
(2) SN 35239-01 through SN 37016-28 (referred to in this AD as
Group ``B'' cylinder assemblies).
(3) Note that the cylinder assembly P/N is at the crankcase end
of the cylinder assembly, and might be difficult to see. As a guide
in determining if your cylinder assemblies are affected, all
affected cylinder assemblies have cylinder head P/N AEL85099. The
cylinder head P/N is at the top of the cylinder head, near the
intake and exhaust valve springs, and is easier to locate than the
cylinder assembly P/N.
(4) Note that the set of numbers appearing on the cylinder,
above and to the left of the SN, in the form of ``123456'' is not
used for determining applicability.

------------------------------------------------------------------------
Unsafe Condition
(d) This AD results from reports of 45 failures with head
separations of ECi cylinder assemblies. We are issuing this AD to
prevent loss of engine power due to cracks at the head-to-barrel
interface in the cylinder assemblies and possible engine failure
caused by separation of a cylinder head, which could result in loss
of control of the aircraft.
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 Cylinder Assemblies Not Replaced Since New
(f) If your engine has not been overhauled or had any cylinder
assemblies replaced since new, no further action is required.
Engines Overhauled or Cylinder Assemblies Replaced Since New
(g) If your engine was overhauled or had a cylinder assembly
replaced since new, do the following:
(1) Before further flight, inspect the maintenance records and
engine logbook to determine if the overhaul or repair facility used
ECi cylinder assemblies, P/N AEL65102, with cylinder head, PN
AEL85099, with a SN 1138-02 through SN 35171-22, or a SN 35239-01
through SN 37016-28, installed.
(2) If the cylinder assemblies are not ECi, P/N AEL65102, no
further action is required.
(3) If the cylinder assemblies are ECi, P/N AEL65102, and if the
serial number is not listed in this AD, no further action is
required.
(4) If the cylinder assemblies are ECi, P/N AEL65102, and if the
serial number is listed in this AD, do the following:
Group ``A'' Cylinder Assemblies
(i) For Group ``A'' cylinder assemblies:
(A) Perform an initial visual inspection as specified in
paragraphs (h) through (j) of this AD, and an initial compression
test as specified in paragraphs (k) through (o) of this AD, within
the next 10 operating hours time-in-service (TIS), if the cylinder
assembly has 350 or more operating hours TIS on the effective date
of this AD, but fewer than 2,000 operating hours TIS.
(B) Perform an initial visual inspection as specified in
paragraphs (h) through (j) of this AD, and an initial compression
test as specified in paragraphs (k) through (o) of this AD, before
exceeding 350 operating hours TIS, if the cylinder assembly has
fewer than 350 operating hours TIS on the effective date of this AD.
(C) Replace cylinder assemblies installed in helicopter engines
within the next 25 operating hours TIS after the effective date of
this AD if the cylinder assembly has 1,500 operating hours TIS or
more on the effective date of this AD.
(D) Replace cylinder assemblies installed in airplane engines
within the next 25 operating hours TIS after the effective date of
this AD if the cylinder assembly has 2,000 operating hours TIS or
more on the effective date of this AD.
(E) Perform repetitive visual inspections as specified in
paragraphs (h) through (j) of this AD, and repetitive compression
tests as specified in paragraphs (k) through (o) of this AD, within
every 50 operating hours TIS.
(F) Replace cylinder assemblies installed in helicopter engines
that pass the visual inspections and compression tests, no later
than 1,500 operating hours TIS after the effective date of this AD.
(G) Replace cylinder assemblies installed in airplane engines
that pass the visual inspections and compression tests, no later
than 2,000 operating hours TIS after the effective date of this AD.
Group ``B'' Cylinder Assemblies
(ii) For Group ``B'' cylinder assemblies:
(A) Perform an initial visual inspection as specified in
paragraphs (h) through (j) of this AD, and initial compression test
as specified in paragraphs (k) through (o) of this AD, within an
additional 10 operating hours TIS.
(B) Replace the cylinder assembly within the next 25 operating
hours TIS after the effective date of this AD if the cylinder
assembly has 350 or more operating hours TIS on the effective date
of this AD.
(C) Replace cylinder assemblies that pass the initial visual
inspections and compression tests, before exceeding 350 operating
hours TIS after the effective date of this AD.
Visual Inspection
(h) Visually inspect around the exhaust valve side, for cracks
or any signs of black or white residue of combustion leakage from
cracks.
(i) Replace cracked cylinder assemblies before further flight.
(j) Information on cylinder assembly visual inspection can be
found in ECi Mandatory Service Bulletin (MSB) No. 08-1, Revision 3,
dated August 19, 2008.
Cylinder Assembly Compression Test
(k) Compression test the cylinder assembly.
(l) Information on cylinder assembly compression testing can be
found in ECi MSB No. 08-1, Revision 3, dated August 19, 2008.
(m) During the compression test, if the cylinder pressure gauge
reads below 70 pounds-per-square-inch, apply a water and
[[Page 53113]]
soap solution to the side of the leaking cylinder, near the head-to-
barrel interface.
(n) Replace the cylinder assembly before further flight, if air
leakage and bubbles are observed on the side of the cylinder
assembly, near the head-to-barrel interface.
(o) Repair or replace the engine cylinder assembly before
further flight if the cause of the low gauge reading in paragraph
(m) of this AD is from leaking intake or exhaust valves, or from
leaking piston rings.
Prohibition of ECi Cylinder Assemblies Affected by This AD
(p) After the effective date of this AD, do not install any ECi
cylinder assembly, P/N AEL65102, with cylinder head, P/N AEL85099,
and with SN 1138-02 through SN 35171-22, or SN 35239-01 through SN
37016-28, onto any engine, and do not attempt to repair or reuse
these ECi cylinder assemblies.
Alternative Methods of Compliance
(q) 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.
Special Flight Permits
(r) Under 14 CFR 39.23, we will not approve special flight
permits for this AD for engines that have failed the visual
inspection or the cylinder assembly compression test required by
this AD.
