ACTION: Final rule; request for comments. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain SAP cast 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. This AD requires removing from service certain SAP part numbered (P/N) cast cylinder assemblies installed in TCM, LE, and AL reciprocating engines. This AD also requires removing from service certain cast cylinder assemblies installed as original equipment in SAP reciprocating engines, or in certain overhauled or repaired SAP reciprocating engines. This AD results from nine separated SAP cylinder assemblies in TCM reciprocating engines and one in LE reciprocating engines. 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. 8089 This AD becomes effective March 12, 2007. We must receive any comments on this AD by April 24, 2007. ADDRESSES: Use one of the following addresses to comment on this AD: • DOT Docket Web site: Go to https://dms.dot.gov and follow the instructions for sending your comments electronically. • Government-wide rulemaking Web site: Go to https://www.regulations.gov and follow the instructions for sending your comments electronically. • Mail: Docket Management Facility; U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL–401, Washington, DC 20590– 0001. • Fax: (202) 493–2251. • Hand Delivery: Room PL–401 on the plaza level of the Nassif Building, 400 Seventh Street, SW., Washington, DC, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION: SAP informed the FAA on July 12, 2006, that at least nine SAP cylinder assemblies installed in TCM 470, 520, and 550 series reciprocating engines and one installed in LE 320, 360, and 540 series reciprocating engines had separated at the cylinder head-to-barrel threaded interface because SAP omitted a heat treat process step during cylinder barrel manufacture. This omission resulted in higher stresses in the cylinder head-tobarrel threaded interface, leading to fatigue cracking and cylinder head separation. The lowest time-in-service (TIS) for a cylinder assembly known to have separated from this defect is 202 hours TIS. SAP isolated this defect to a specific production lot of 1,354 barrel forgings used as original equipment on SAP O–360 engines and in SAP PMA cylinder assemblies as replacement parts for various TCM, LE, and AL engine models. This AD addresses the barrels used in SAP PMA cylinders installed in the engines listed below.

The Class E airspace designations listed in this document will be published subsequently in that Order. The Rule DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 71 [Docket No. FAA–2005–20381; Airspace Docket No. 05–ANM–3] Revision of Class E Airspace; Gillette, WY Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: SUMMARY: This action will revise the Class E airspace at Gillette, WY. Additional Class E airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Gillette-Campbell County Airport. This will improve the safety of Instrument Flight Rules (IFR) aircraft executing the new RNAV GPS SIAP at Gillette-Campbell County Airport, Gillette, WY. DATES: Effective Date: 0901 UTC, May 10, 2007. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments. FOR FURTHER INFORMATION CONTACT: Ed Haeseker, Federal Aviation Administration, Western Service Area, System Support, 1601 Lind Avenue SW., Renton, WA, 98055–4056; telephone (425) 227–2527. SUPPLEMENTARY INFORMATION: History On August 11, 2006, the FAA published in the Federal Register a notice of proposed rulemaking to revise Class E airspace at Gillette, WY, (71 FR 46133). This action would improve the safety of Instrument Flight Rules (IFR) aircraft executing this new RNAV GPS approach procedure at GilletteCampbell County Airport, Gillette WY. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by revising Class E airspace at Gillette, WY. Additional controlled airspace is necessary to accommodate IFR aircraft executing a new RNAV (GPS) approach procedure at Gillette-Campbell Airport, Gillette WY. The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 71 Airspace, Incorporation by reference, Navigation (air). Adoption of the Amendment In consideration of the foregoing, the Federal Aviation Administration amends 14 CFR part 71 as follows: I PART 71—DESIGNATION OF CLASS A, B, C, D, AND E AIRSPACE AREAS; AIR TRAFFIC SERVICE ROUTES; AND REPORTING POINTS 1. The authority citation for 14 CFR part 71 continues to read as follows: I Authority: 49 U.S.C. 106(g), 40103, 40113, 40120; E.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain SAP cast 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. This AD requires removing 
from service certain SAP part numbered (P/N) cast cylinder assemblies 
installed in TCM, LE, and AL reciprocating engines. This AD also 
requires removing from service certain cast cylinder assemblies 
installed as original equipment in SAP reciprocating engines, or in 
certain overhauled or repaired SAP reciprocating engines. This AD 
results from nine separated SAP cylinder assemblies in TCM 
reciprocating engines and one in LE reciprocating engines. 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: This AD becomes effective March 12, 2007.
    We must receive any comments on this AD by April 24, 2007.

SUPPLEMENTARY INFORMATION: SAP informed the FAA on July 12, 2006, that 
at least nine SAP cylinder assemblies installed in TCM 470, 520, and 
550 series reciprocating engines and one installed in LE 320, 360, and 
540 series reciprocating engines had separated at the cylinder head-to-
barrel threaded interface because SAP omitted a heat treat process step 
during cylinder barrel manufacture. This omission resulted in higher 
stresses in the cylinder head-to-barrel threaded interface, leading to 
fatigue cracking and cylinder head separation. The lowest time-in-
service (TIS) for a cylinder assembly known to have separated from this 
defect is 202 hours TIS. SAP isolated this defect to a specific 
production lot of 1,354 barrel forgings used as original equipment on 
SAP O-360 engines and in SAP PMA cylinder assemblies as replacement 
parts for various TCM, LE, and AL engine models. This AD addresses the 
barrels used in SAP PMA cylinders installed in the engines listed 
below.

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 
SAP cast cylinder assemblies that have as original equipment, or have 
been overhauled or repaired using SAP part numbers listed in the table 
above. 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 cast cylinder assemblies listed in the table 
above, 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 of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause exists for making this amendment effective in less than 30 days.

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-2006-25948; 
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 https://
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

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 the discovery of nine separated SAP 
cylinder assemblies installed in TCM 470, 520, and 550 series 
reciprocating engines and one separated SAP cylinder assembly 
installed in LE 320, 360, and 540 series reciprocating engines. 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 Cast 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 flanges are 
marked: SA47000L-A1, SA47000L-A20P, SA47000S-A1, SA47000S-A20P, 
SA47000S-A21P, SA52000-A1, SA52000-A20P, SA52000-A21P, SA52000-A22P, 
SA52000-A23P, SA55000-A1, or SA55000-A20P or SL32000W-A1, SL32000W-
A20P, SL32000W-A21P, SL32000WH-A1, SL32000WH-A20P, SL32006W-A1, 
SL32006W-A20P, SL32006W-A21P, SL36000TW-A1, SL36000TW-A20P, 
SL36000TW-A21P, SL36000TW-A22P, SL36000W-A1, SL36000W-A20P, 
SL36000W-A21P, SL36006W-A1, SL36006W-A20P, or SL36006W-A21P.

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 
36WJ058182, or 366WE056944 through 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
