AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).

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.

2
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-to-barrel 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
ADDRESSES. Include “AD Docket No. FAA-2007-25948; Directorate Identifier 2006-NE-32-AD”
in the subject line of your comments. We specifically invite comments on the overall regulatory,
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 information you provide. We will also post a report summarizing each substantive verbal
contact with FAA personnel concerning this AD. Using the search function of the DMS Web site,
anyone can find and read the comments in any of our dockets, including the name of the individual
who sent the comment (or signed the comment on behalf of an association, business, labor union,
etc.). You may review the DOT's complete Privacy Act Statement in the Federal Register published
on April 11, 2000 (65 FR 19477-78) or you may visit http://dms.dot.gov.

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 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.

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.

3
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-A20P, SA47000S-A21P, SA52000-

Cylinder Assembly Removal

(g) Remove all cylinder assemblies with a serial number of 47LE053559 through 47LF053643,
or 47SE054212 through 47SF054251, or 52D0531708 through 52H0532197, or 55E05223 through
55G05289, or 32WE059006 through 32WF059067, or 32WHE05379 through 32WHE05392, or
326WF055517 through 326WF055532, or 36TWF05430 through 36TWG05453, or 36WF058058
through 36WG058124, or 366WE056944 through 366WF057061, or 366WF057150 through
366WF057232, or 366WF057259 through 366WG057534, or 366WG057556, 366WG057569,

366WJ057776, or 366WL058131 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.

(h) For cylinder assemblies with more than 150 hours total TIS on the effective date of this AD,
a 10 hour TIS extension is permitted for the purpose of flying the aircraft to a location where
maintenance action can be done to meet the requirements of this AD.

(i) After the effective date of this AD, do not install any cylinder assemblies with P/Ns
SA47000L-A1, SA47000L-A20P, SA47000S-A1, SA47000S-A20P, SA47000S-A21P, SA52000-
