Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2005-22358; Directorate Identifier 2005-NE-20-AD; 
Amendment 39-14431; AD 2005-26-10]
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 ``Classic Cast'', installed. This AD requires replacing these 
ECi cylinder assemblies. This AD results from reports of about 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.

DATES: This AD becomes effective January 31, 2006.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in Room PL-401 on the plaza level of the Nassif 
Building, 400 Seventh Street, SW., Washington, DC.

FOR FURTHER INFORMATION CONTACT: Peter Hakala, Aerospace Engineer, 
Special Certification Office, FAA, Rotorcraft Directorate, 2601 Meacham 
Blvd., Fort Worth, TX 76193; telephone (817) 222-5145; fax (817) 222-
5785.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed AD. The proposed AD applies to certain 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 published the proposed AD in the Federal Register on 
September 9, 2005 (70 FR 53586). That action proposed to require 
replacing these ECi cylinder assemblies.

Examining the AD Docket

    You may examine the docket that contains the AD, any comments 
received, and any final disposition in person at the Docket Management 
Facility Docket Office between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The Docket Office (telephone (800) 
647-5227) is located on the plaza level of the Department of 
Transportation Nassif Building at the street address stated in 
ADDRESSES. Comments will be available in the AD docket shortly after 
the DMS receives them.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Request To Extend the Proposed AD Comment Period

    One commenter, a law office representing ECi, requests we extend 
the proposed AD comment period an additional 90 days. We do not agree. 
We have worked with ECi for the past four years regarding the safety 
and airworthiness issues with the affected ECi cylinder assemblies. ECi 
is very familiar with the problems with these cylinder assemblies. ECi 
published Service Bulletin No. 05-08, dated September 1, 2005, for the 
identification and warranty of the affected cylinder assemblies. 
Evidence of ECi's awareness of the problem is confirmed by the 
extensive correspondence with the FAA regarding the service 
difficulties with P/N AEL65102 ``Classic Cast'' cylinder assemblies. 
For these reasons, and because of the minimal amount of comments 
received (two) on the proposed AD, we find it unnecessary to extend the 
proposed AD comment period.

Request To Allow Cylinder Assembly Removal at Normal Operating Time-
Between-Overhaul

    One commenter, ECi, requests that we allow affected cylinder 
assemblies to be removed at the normal engine operating time-between-
overhaul. We do not agree. We have carefully reviewed ECi's request. 
Both ECi and the FAA participated in the Alloytek Metallurgical 
Services, Inc. examination and analysis. The examination and

[[Page 76386]]

analysis showed that the failure mode of the ECi cylinder assemblies, 
P/N AEL65102, is most likely due to metal fatigue. The proposed AD 
required replacing affected cylinder assemblies at no later than 800 
operating hours-in-service. The failure data records show that a longer 
operating time for the affected cylinder assemblies would jeopardize 
aircraft safety. We have not changed 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.

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 will take about two work hours per 
engine to perform the 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 will cost about $1,000 per cylinder assembly. Based on 
these figures, we estimate that the total cost of the 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 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.

Unsafe Condition

    (d) This AD results from reports of about 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.
    (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.
