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.

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. 

53588 Federal Register / Vol. 70, No. 174 / Friday, September 9, 2005 / Proposed Rules 

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. 

53594 Federal Register / Vol. 70, No. 174 / Friday, September 9, 2005 / Proposed Rules 

(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,
