AGENCY: Federal Aviation 

Administration (FAA), Department of

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is revising an 

existing airworthiness directive (AD) for 

certain SAP cylinder assemblies 

installed in Teledyne Continental 

Motors (TCM) 470, 520, and 550 series 

reciprocating engines, Lycoming 

Engines (LE) 320, 360, and 540 series 

reciprocating engines, Avco Lycoming 

(AL) 540 series reciprocating engines, 

and Superior Air Parts, Inc. (SAP) 360 

series reciprocating engines. That AD 

currently requires removing from 

service certain SAP part numbered 

(P/N) cylinder assemblies installed in 

TCM, LE, and AL reciprocating engines. 

That AD also requires removing from 

service certain cylinder assemblies 

installed as original equipment in SAP 

reciprocating engines, or in certain 

overhauled or repaired SAP 

reciprocating engines. 

This AD continues to require those 

same actions. This AD results from 

comments from the Public on the 

existing AD. We are issuing this AD to 

prevent cylinder separation that can 

lead to engine failure, a possible engine 

compartment fire, and damage to the 

airplane. 

DATES: Effective May 7, 2007. 

We must receive any comments on 

this AD by June 1, 2007.

SUPPLEMENTARY INFORMATION: On 

February 13, 2007, the FAA issued AD 

2007–04–19, Amendment 39–14951 (72 

FR 8089, February 23, 2007). That AD 

requires removing from service certain 

installed SAP cylinder assemblies, 

listed in that AD by P/N and serial 

number (SN), no later than 150 hours 

total time-in-service (TIS) to preclude 

cylinder head fatigue failure and 

separation at the head-to-barrel threaded 

interface. That AD was the result of nine 

separated SAP cylinder assemblies in 

TCM reciprocating engines and one in a 

LE reciprocating engine. That condition, 

if not corrected, could result in cylinder 

separation that can lead to engine 

failure, a possible engine compartment 

fire, and damage to the airplane. 

Actions Since We Issued AD 2007–04– 

19 

Since we issued AD 2007–04–19, we 

received comments that cause us to 

better define and reduce the 

applicability of this AD. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comments received. 

Request To Provide a Range of Dates 

That SAP Manufactured the Suspect 

Cylinders 

A number of commenters ask us to 

include the date range when SAP 

manufactured the cylinders. The 

commenters state that including the 

range of dates will help users to 

determine if they need to investigate 

further and will eliminate unnecessary 

time and money spent to determine if a 

suspect cylinder assembly is installed 

on their engine. 

We agree. We changed the 

applicability to provide a date range to 

help narrow the applicability. Also, we 

clarified the SN range to narrow the 

applicability even further. 

Minor Editorial Changes 

We included some minor editorial 

changes in this AD to clarify some 

nomenclature. 

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 with the changes described 

previously. We have determined that 

these changes will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

FAA’s Determination and Requirements 

of This AD 

The unsafe condition described 

previously is likely to exist or develop 

on other TCM 470, 520, and 550; LE 

320, 360, and 540; AL 540, and SAP 360 

series reciprocating engines of the same 

type design with certain SAP cylinder 

assemblies that have a part number 

listed in this AD. For that reason, we are 

issuing this AD to prevent cylinder 

separation which can lead to engine 

failure, a possible engine compartment 

fire, and damage to the airplane. This 

AD requires removing from service 

installed SAP cylinder assemblies listed 

in this AD, no later than 150 hours total 

TIS to preclude cylinder head fatigue 

failure and separation at the head-tobarrel threaded interface. 

FAA’s Determination for No Prior 

Public Notice 

Since we do not anticipate adverse 

public interest in this action, a situation 

exists that allows for immediate 

adoption of this AD, and we have found 

that notice and opportunity for further 

public comment before issuing this AD 

are unnecessary. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to send us any 

written relevant data, views, or 

arguments regarding this AD. Send your 

comments to an address listed under 


rmajette on PROD1PC67 with RULES

economic, environmental, and energy 

aspects of the rule that might suggest a 

need to modify it. 

We will post all comments we 

receive, without change, to http:// 

dms.dot.gov, including any personal

Comments will be available in the AD 

docket shortly after the DMS receives 

them. 

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 the 

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 comments from 

the Public on the existing AD. We are issuing 

this AD to prevent cylinder separation that 

can lead to engine failure, a possible engine 

compartment fire, and damage to the 

airplane. 

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. 

Determining Which Cylinder Assemblies Are 

Installed 

(f) If aircraft engine records do not list the 

P/N of the cylinder installed during engine 

overhaul or repair, visually inspect the 

cylinders. The affected SAP cylinder head 

barrel flanges are marked: SA47000L–A1, 

SA47000L–A20P, SA47000S–A1, SA47000S–
