ACTION: Final rule; request for comments. rmajette on PROD1PC67 with RULES AGENCY: 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.

FOR FURTHER INFORMATION CONTACT: Jurgen Priester, Aerospace Engineer, Special Certification Office, FAA, Rotorcraft Directorate, Southwest Regional Headquarters, 2601 Meacham Blvd., Fort Worth, Texas 76137; e-mail: Jurgen.E. Priester@faa.gov; telephone (817) 222–5159; fax (817) 222–5785. 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. 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. 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. 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 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 PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 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. 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 E:\FR\FM\02APR1.SGM 02APR1 15604 Federal Register / Vol. 72, No. 62 / Monday, April 2, 2007 / Rules and Regulations ADDRESSES.

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.

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.

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

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.

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-A1, SA52000-A20P, SA52000-A21P, SA52000-A22P,
