ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
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 ‘‘Titan’’, installed. This
proposed AD would 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-inservice. This proposed AD results from
reports of 45 failures with head
separations of ECi cylinder assemblies.
We are proposing 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: We must receive any comments
on this proposed AD by July 18, 2008.

Discussion
In November 2005, we started
receiving reports from the National
Transportation Safety Board, FAA Flight
Standards District Offices, and other
FAA offices, of failures of ECi cylinder
assemblies, P/N AEL65102 series,
installed on Lycoming Engines models
320, 360, and 540 series, parallel valve
reciprocating engines. ECi holds the
Parts Manufacturer Approval (PMA) for
the affected cylinder assemblies.
Parallel valve Lycoming reciprocating
engines are identified by the intake and
exhaust valves in a parallel
configuration. We investigated the
failures and determined they were
caused by fatigue cracking of the
aluminum alloy cylinder head at the
head-to-barrel interface.
We identified two manufacturing
groups of cylinder assemblies requiring
action. Group ‘‘A’’ cylinder assemblies
(serial number (SN) 1138–02 through
SN 35171–22) require initial and
repetitive visual inspections and
compression tests, and removal from
service at 2,000 operating hours time-inservice (TIS), unless installed in
helicopters. If installed in helicopters,
group ‘‘A’’ cylinder assemblies require
the same actions, but must be removed
from service at 1,500 operating hours
TIS. The helicopter ECi cylinder
assemblies are removed at 1,500 hours,
because the more strenuous operating
conditions require a shorter time
between overhaul (TBO). Group ‘‘B’’
cylinder assemblies (SN 35239–01
through SN 37016–28) require the same
initial visual inspection and
compression test, but must be removed
from service before exceeding 350
operating hours TIS. All of the affected
cylinder assemblies are marked with
cylinder head P/N AEL85099. This
unsafe condition, if not corrected, could
result in loss of engine power due to
cracks in the cylinder assembly and
possible engine failure caused by
cylinder head separation.
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:
• Determining if Group ‘‘A’’ or Group
‘‘B’’ ECi cylinder assemblies, P/N
AEL65102 series ‘‘Titan’’, with cylinder
head P/N AEL85099, are installed on
your engine.
• For any Group ‘‘A’’ cylinder
assembly, performing initial and
PO 00000
Frm 00019
Fmt 4702
Sfmt 4702
28757
repetitive visual inspections and
compression tests, and replacement not
later than 2,000 operating hours TIS or
within 25 operating hours TIS if the
cylinder assembly exceeds 2,000
operating hours TIS on the effective date
of the proposed AD.
• For any Group ‘‘A’’ cylinder
assembly installed in a helicopter,
performing the same initial and
repetitive visual inspections and
compression tests, but replacement not
later than 1,500 operating hours TIS or
within 25 operating hours TIS if the
cylinder assembly exceeds 1,500
operating hours TIS on the effective date
of the proposed AD.
• For any Group ‘‘B’’ cylinder
assembly, performing the same initial
visual inspection and compression test,
and replacement not later than 350
operating hours TIS or within 25
operating hours TIS if the cylinder
assembly exceeds 350 operating hours
TIS on the effective date of the proposed
AD.
Costs of Compliance
We estimate that this proposed AD
would affect 13,000 ECi cylinder
assemblies installed in aircraft of U.S.
registry. The visual inspection and
compression tests would take about 4
work-hours for each engine. An
individual cylinder replacement would
require $1,100 for parts and 6 workhours. Lycoming engines with a set of
4 ECi cylinders would require 12 workhours for the cylinder replacement.
Lycoming engines with a set of 6 ECi
cylinders would require 16 work-hours
for the cylinder replacement. We
estimate 18 percent of the affected
population of cylinders will be
replaced. The total cost of the proposed
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
E:\FR\FM\19MYP1.SGM
19MYP1
28758
Federal Register / Vol. 73, No. 97 / Monday, May 19, 2008 / Proposed Rules
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 AD:
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. You may get a copy
of this summary at the address listed
under ADDRESSES.

Applicability
The Proposed Amendment
Under the authority delegated to me
by the Administrator, the Federal
Aviation Administration proposes to
amend 14 CFR part 39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new airworthiness
directive:
Engine Components Inc. (ECi): Docket No.
FAA–2008–0052; Directorate Identifier
2008–NE–01–AD.
Comments Due Date
(a) The Federal Aviation Administration
(FAA) must receive comments on this
airworthiness directive (AD) action by July
18, 2008.
(b) None.
(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
Compliance
(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.
(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.

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 ``Titan'', installed. This proposed AD would 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. This proposed AD results
from reports of 45 failures with head separations of ECi cylinder
assemblies. We are proposing 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: We must receive any comments on this proposed AD by July 18,
2008.
ADDRESSES: Use one of the following addresses to comment on this
proposed AD.

Discussion
In November 2005, we started receiving reports from the National
Transportation Safety Board, FAA Flight Standards District Offices, and
other FAA offices, of failures of ECi cylinder assemblies, P/N AEL65102
series, installed on Lycoming Engines models 320, 360, and 540 series,
parallel valve reciprocating engines. ECi holds the Parts Manufacturer
Approval (PMA) for the affected cylinder assemblies. Parallel valve
Lycoming reciprocating engines are identified by the intake and exhaust
valves in a parallel configuration. We investigated the failures and
determined they were caused by fatigue cracking of the aluminum alloy
cylinder head at the head-to-barrel interface.
We identified two manufacturing groups of cylinder assemblies
requiring action. Group ``A'' cylinder assemblies (serial number (SN)
1138-02 through SN 35171-22) require initial and repetitive visual
inspections and compression tests, and removal from service at 2,000
operating hours time-in-service (TIS), unless installed in helicopters.
If installed in helicopters, group ``A'' cylinder assemblies require
the same actions, but must be removed from service at 1,500 operating
hours TIS. The helicopter ECi cylinder assemblies are removed at 1,500
hours, because the more strenuous operating conditions require a
shorter time between overhaul (TBO). Group ``B'' cylinder assemblies
(SN 35239-01 through SN 37016-28) require the same initial visual
inspection and compression test, but must be removed from service
before exceeding 350 operating hours TIS. All of the affected cylinder
assemblies are marked with cylinder head P/N AEL85099. This unsafe
condition, if not corrected, could result in loss of engine power due
to cracks in the cylinder assembly and possible engine failure caused
by cylinder head separation.
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:
Determining if Group ``A'' or Group ``B'' ECi cylinder
assemblies, P/N AEL65102 series ``Titan'', with cylinder head P/N
AEL85099, are installed on your engine.
For any Group ``A'' cylinder assembly, performing initial
and repetitive visual inspections and compression tests, and
replacement not later than 2,000 operating hours TIS or within 25
operating hours TIS if the cylinder assembly exceeds 2,000 operating
hours TIS on the effective date of the proposed AD.
For any Group ``A'' cylinder assembly installed in a
helicopter, performing the same initial and repetitive visual
inspections and compression tests, but replacement not later than 1,500
operating hours TIS or within 25 operating hours TIS if the cylinder
assembly exceeds 1,500 operating hours TIS on the effective date of the
proposed AD.
For any Group ``B'' cylinder assembly, performing the same
initial visual inspection and compression test, and replacement not
later than 350 operating hours TIS or within 25 operating hours TIS if
the cylinder assembly exceeds 350 operating hours TIS on the effective
date of the proposed AD.
Costs of Compliance
We estimate that this proposed AD would affect 13,000 ECi cylinder
assemblies installed in aircraft of U.S. registry. The visual
inspection and compression tests would take about 4 work-hours for each
engine. An individual cylinder replacement would require $1,100 for
parts and 6 work-hours. Lycoming engines with a set of 4 ECi cylinders
would require 12 work-hours for the cylinder replacement. Lycoming
engines with a set of 6 ECi cylinders would require 16 work-hours for
the cylinder replacement. We estimate 18 percent of the affected
population of cylinders will be replaced. The total cost of the
proposed 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
[[Page 28758]]
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 AD:
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. You may get a copy of this summary at the
address listed under ADDRESSES.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
The Proposed Amendment
Under the authority delegated to me by the Administrator, the
Federal Aviation Administration proposes to amend 14 CFR part 39 as
follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The FAA amends Sec. 39.13 by adding the following new
airworthiness directive:
Engine Components Inc. (ECi): Docket No. FAA-2008-0052; Directorate
Identifier 2008-NE-01-AD.
Comments Due Date
(a) The Federal Aviation Administration (FAA) must receive
comments on this airworthiness directive (AD) action by July 18,
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, P/N
AEL85099, with a SN 1138-02 through SN
[[Page 28764]]
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 1,
dated April 8, 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 1, dated April 8, 2008.
(m) During the compression test, if the cylinder pressure gauge
reads below 70 pounds-per-square-inch, apply a water and 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.
