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

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-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
[[Page 15604]]
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.
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.
