Download as PDF 37955 Proposed Rules Federal Register Vol. 74, No. 145 Thursday, July 30, 2009 This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2008–0052; Directorate Identifier 2008–NE–01–AD] RIN 2120–AA64 Airworthiness Directives; Engine Components, Inc. (ECi) Reciprocating Engine Cylinder Assemblies erowe on DSK5CLS3C1PROD with PROPOSALS-1 AGENCY: Federal Aviation Administration (FAA), 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 ‘‘Titan,’’ installed. That AD currently 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-inservice. This proposed AD would require the same actions, but for an expanded population of cylinder assemblies. This proposed AD results from reports of 10 additional cylinder head separations since issuing AD 2008–19–05, on cylinder serial numbers not listed in that AD. We are proposing this AD to prevent loss of engine power due to cracks at the head-to-barrel interface 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 September 28, 2009.

Comments will be available in the AD docket shortly after receipt. Discussion The FAA proposes to amend 14 CFR part 39 by superseding AD 2008–19–05, Amendment 39–15672 (73 FR 53105, September 15, 2008). That 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-inservice. That AD was the result of reports of 45 failures with head separations of ECi cylinder assemblies. That condition, if not corrected, could result in 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. Actions Since AD 2008–19–05 Was Issued Since AD 2008–19–05 was issued, we received reports of 10 additional cylinder head separations, on cylinder serial numbers not listed in that AD. To date, there have been a total of 55 head separations resulting in engine shutdowns and emergency landings in airplanes and helicopters. 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, which 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. The proposed AD would require: E:\FR\FM\30JYP1.SGM 30JYP1 37956 Federal Register / Vol. 74, No. 145 / Thursday, July 30, 2009 / Proposed Rules • 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 time-inservice (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. • Expanding the serial numbers affected of Group ‘‘B’’ cylinder assemblies, and 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 18,000 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 would be replaced. We estimate the total cost of the AD to U.S. operators to be $10,172,000. Our estimate is exclusive of any possible warranty coverage. erowe on DSK5CLS3C1PROD with PROPOSALS-1 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 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. See the ADDRESSES section for a location to examine the regulatory evaluation. 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. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Amendment 39–15672 (73 FR 53105, September 15, 2008) and by adding a new airworthiness directive to read as follows: 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 September 28, 2009. Affected ADs (b) This AD supersedes AD 2008–19–05, Amendment 39–15672. Applicability (c) If your engine has not been overhauled, or not had any cylinder assemblies replaced since new, no further action is required. (d) 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 42179–30 (referred to in this AD as Group ‘‘B’’ cylinder assemblies). (3) 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) 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.

E9–18118 Filed 7–29–09; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2009–0658; Directorate Identifier 2009–NM–058–AD] RIN 2120–AA64 Airworthiness Directives; McDonnell Douglas Model DC–9–14, DC–9–15, and DC–9–15F Airplanes; and McDonnell Douglas Model DC–9–20, DC–9–30, DC–9–40, and DC–9–50 Series Airplanes erowe on DSK5CLS3C1PROD with PROPOSALS-1 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) that applies to all McDonnell Douglas Model DC–9–14, DC–9–15, and DC–9–15F airplanes; and McDonnell Douglas Model DC–9–20, DC–9–30, DC–9–40, and DC–9–50 series airplanes. The existing AD currently requires repetitive inspections for cracks of the main landing gear (MLG) shock strut cylinder, and related investigative and corrective actions if necessary. This proposed AD would add more work on airplanes that have main landing gear shock struts with certain identified part numbers. This proposed AD results from two reports of a collapsed MLG and a report of cracks in two MLG cylinders. We are proposing this AD to detect and correct fatigue cracks in the shock strut cylinder of the MLG, which VerDate Nov<24>2008 14:58 Jul 29, 2009 Jkt 217001 could result in a collapsed MLG during takeoff or landing, and possible reduced structural integrity of the airplane. DATES: We must receive comments on this proposed AD by September 14, 2009.

Discussion On September 7, 2005, we issued AD 2005–19–08, amendment 39–14273 (70 FR 54616, September 16, 2005), for all McDonnell Douglas Model DC–9–14, DC–9–15, and DC–9–15F airplanes; and McDonnell Douglas Model DC–9–20, DC–9–30, DC–9–40, and DC–9–50 series airplanes. That AD requires repetitive inspections for cracks of the main landing gear (MLG) shock strut cylinder, and related investigative and corrective actions if necessary. That AD resulted from two reports of a collapsed MLG and a report of cracks in two MLG cylinders. We issued that AD to detect and correct fatigue cracks in the shock strut cylinder of the MLG, which could result in a collapsed MLG during takeoff or landing, and possible reduced structural integrity of the airplane. Actions Since Existing AD Was Issued Since we issued AD 2005–19–08, the manufacturer revised the service information referenced in that AD, i.e., Boeing Alert Service Bulletin DC9– 32A350, Revision 1, dated August 3, 2005, to add more work on airplanes that have shock struts with part numbers 5924400–505 and 5924400– 506. Relevant Service Information We have reviewed Boeing Alert Service Bulletin DC9–32A350, Revision 2, dated March 20, 2009, which specifies that shock struts having part numbers 5924400–505 and 5924400– 506 must be included with those struts that require repetitive non-destructive testing inspections. The remaining actions are otherwise unchanged. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe E:\FR\FM\30JYP1.SGM 30JYP1

RIN 2120-AA64


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

AGENCY: Federal Aviation Administration (FAA), 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 ``Titan,'' installed. That AD currently 
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 proposed AD would 
require the same actions, but for an expanded population of cylinder 
assemblies. This proposed AD results from reports of 10 additional 
cylinder head separations since issuing AD 2008-19-05, on cylinder 
serial numbers not listed in that AD. We are proposing this AD to 
prevent loss of engine power due to cracks at the head-to-barrel 
interface 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 September 
28, 2009.

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

Discussion

    The FAA proposes to amend 14 CFR part 39 by superseding AD 2008-19-
05, Amendment 39-15672 (73 FR 53105, September 15, 2008). That 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. That AD was the result of 
reports of 45 failures with head separations of ECi cylinder 
assemblies. That condition, if not corrected, could result in 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.

Actions Since AD 2008-19-05 Was Issued

    Since AD 2008-19-05 was issued, we received reports of 10 
additional cylinder head separations, on cylinder serial numbers not 
listed in that AD. To date, there have been a total of 55 head 
separations resulting in engine shutdowns and emergency landings in 
airplanes and helicopters.

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, 
which 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. The 
proposed AD would require:

[[Page 37956]]

     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 time-in-service (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.
     Expanding the serial numbers affected of Group ``B'' 
cylinder assemblies, and 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 18,000 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 would be replaced. We estimate the total cost 
of the AD to U.S. operators to be $10,172,000. 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 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. See the ADDRESSES section for a location 
to examine the regulatory evaluation.

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 removing Amendment 39-15672 (73 FR 
53105, September 15, 2008) and by adding a new airworthiness directive 
to read as follows:

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 September 
28, 2009.

Affected ADs

    (b) This AD supersedes AD 2008-19-05, Amendment 39-15672.

Applicability

    (c) If your engine has not been overhauled, or not had any 
cylinder assemblies replaced since new, no further action is 
required.
    (d) 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 42179-30 (referred to in this AD as 
Group ``B'' cylinder assemblies).
    (3) 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) 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

    (e) This AD results from reports of 10 additional cylinder head 
separations since issuing AD 2008-19-05, on cylinder serial numbers 
not listed in that AD. 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

    (f) 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 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 42179-30, 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 
SN is not listed in this AD, no further action is required.
    (4) If the cylinder assemblies are ECi, P/N AEL65102, and if the 
SN 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 (i) of this AD, and an initial compression 
test as specified in paragraphs (j) through (n) 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 (i) of this AD, and an initial compression 
test as specified in paragraphs (j) through (n) of this AD, within 
the next 10 operating hours TIS, or before exceeding 350 operating 
hours TIS, whichever occurs later, 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 (i) of this AD, and repetitive compression 
tests as specified in paragraphs (j) through (n) 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 (i) of this AD, and initial compression test 
as specified in paragraphs (j) through (n) of this AD, within the 
next 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 each cylinder head 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.

Cylinder Assembly Compression Test

    (j) Perform a standard cylinder differential compression test.
    (k) 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.
    (l) 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.
    (m) Repair or replace the engine cylinder assembly before 
further flight if the cause of the low gauge reading in paragraph 
(l) of this AD is from leaking intake or exhaust valves, or from 
leaking piston rings.

Prohibition of ECi Cylinder Assemblies Affected by This AD

    (n) 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 
42179-30, onto any engine, and do not attempt to repair or reuse 
these ECi cylinder assemblies.

Alternative Methods of Compliance

    (o) The Manager, Special Certification Office, has the authority 
to approve alternative methods of compliance for this

[[Page 37963]]

AD if requested using the procedures found in 14 CFR 39.19.

Special Flight Permits

    (p) Under 14 CFR part 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.
