Download as PDF 67568 Federal Register / Vol. 72, No. 229 / Thursday, November 29, 2007 / Rules and Regulations Effective Date the FAA amends 14 CFR part 39 as follows: (a) This AD becomes effective on December 4, 2007. PART 39—AIRWORTHINESS DIRECTIVES Affected ADs (b) None. 1. The authority citation for part 39 continues to read as follows: I Applicability Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): I 2007–24–13 Cirrus Design Corporation: Amendment 39–15279; Docket No. FAA–2007–0250; Directorate Identifier 2007–CE–091–AD. (c) This AD applies to Model SR22 airplanes, serial numbers 2334, 2420, and 2438 through 2749, that are certificated in any category. Unsafe Condition (d) This AD results from reports of pilots’ inability to move the aileron control without using excessive force when flying in freezing conditions. Moisture entered through a gap at the interface of the left and right outboard wing tips and wing structure. The moisture traveled along the aft wing shear web, accumulated below the aileron control pulley, and froze at an altitude with an outside air temperature below freezing. When this moisture is exposed to freezing conditions, operation of the aileron control pulley is impaired. We are issuing this AD to prevent moisture from accumulating along the wing shear web where it may freeze in certain conditions. This condition could result in operational failure of the aileron control pulley, which could lead to loss of control. Compliance (e) To address this problem, you must do the following, unless already done: Actions Compliance Procedures Install a drain hole in the left and right outboard wing tips. At whichever of the following occurs first: (1) Within the next 10 hours time-in-service after December 4, 2007 (the effective date of this AD); or (2) Within the next 30 days after December 4, 2007 (the effective date of this AD). Follow Cirrus Design Service Bulletin SB 2X– 57–08, dated November 2, 2007.

ACTION: Final rule; request for comments. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 768– 60, 772–60, and 772B–60 turbofan engines. That AD currently requires initial and repetitive on-wing or in-shop inspections of the high pressure/ intermediate pressure (HP/IP) turbine bearing oil feed tube heat shield. This AD requires the same actions but introduces a terminating action to the repetitive inspections. This AD results PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 from RR introducing a revised HP/IP turbine bearing support structure as terminating action to the repetitive inspections of the HP/IP turbine bearing oil feed tube heat shield. We are issuing this AD to prevent an uncontained failure of the HP turbine disc and damage to the airplane. DATES: Effective December 14, 2007. The Director of the Federal Register previously approved the incorporation by reference of certain publications listed in the regulations as of December 19, 2006 (71 FR 66229, November 14, 2006).

SUPPLEMENTARY INFORMATION: On November 3, 2006, the FAA issued AD 2006–23–11, Amendment 39–14823 (71 FR 66229, November 14, 2006). That AD requires initial and repetitive on-wing or in-shop inspections of the HP/IP turbine bearing oil feed tube heat shield. That AD was the result of a report that a damaged outer heat shield caused fretting of the oil feed tubes. That condition, if not corrected, could result in an uncontained failure of the HP turbine disc and damage to the airplane. Actions Since AD 2006–23–11 Was Issued Since that AD was issued, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, recently notified us that RR introduced a revised HP/IP turbine bearing support structure to terminate the repetitive inspections. This AD requires initial and repetitive on-wing or in-shop inspections of the HP/IP turbine bearing oil feed tube heat shield, and requires revising the HP/IP turbine bearing support structure as terminating action to the repetitive inspections in this AD. We are issuing this AD to prevent an uncontained failure of the HP turbine disc and damage to the airplane. rmajette on PROD1PC64 with RULES Relevant Service Information We have reviewed and approved the technical contents of RR Service Bulletin (SB) No. RB.211–72–F117, Revision 2, dated September 25, 2006, RR SB No. RB.211–72–F227, Revision 1, dated October 8, 2007, and RR Immediate Operational Request SB No. RB.211–72–F048, Revision 11, dated September 9, 2006, that describe procedures for revising the HP/IP turbine bearing support structure. EASA classified these SBs as mandatory and issued AD 2007–0260 in order to ensure the airworthiness of these RR engines in Europe. Bilateral Airworthiness Agreement These engine models are manufactured in the United Kingdom and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the VerDate Aug<31>2005 14:40 Nov 28, 2007 Jkt 214001 applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, EASA has kept the FAA informed of the situation described above. We have examined the findings of EASA, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States. FAA’s Determination and Requirements of This AD Although no airplanes that are registered in the United States use these Trent 768–60, 772–60, and 772B–60 turbofan engines, the possibility exists that these engines could be used on airplanes that are registered in the United States in the future. The unsafe condition described previously is likely to exist or develop on other Trent 768– 60, 772–60, and 772B–60 turbofan engines of the same type design. We are issuing this AD to prevent an uncontained failure of the HP turbine disc and damage to the airplane. This AD requires initial and repetitive onwing or in-shop inspections of the HP/ IP turbine bearing oil feed tube heat shield, and requires revising the HP/IP turbine bearing support structure as terminating action to the repetitive inspections in this AD. You must use the service information described previously to perform the actions required by this AD. FAA’s Determination of the Effective Date Since there are currently no domestic operators of this engine model, notice and opportunity for public comment before issuing this AD are unnecessary. Therefore, a situation exists that allows the immediate adoption of this regulation. 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–2006–26052; Directorate Identifier 2006–NE–30–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:// www.regulations.gov, including any personal information you provide. We PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 67569 will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of the FDMS 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). Examining the AD Docket You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is the same as the Mail address provided in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. 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; E:\FR\FM\29NOR1.SGM 29NOR1 67570 Federal Register / Vol. 72, No. 229 / Thursday, November 29, 2007 / Rules and Regulations 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.

Box 25082, Oklahoma City, OK 73125) telephone: (405) 954–4164. 14 CFR Part 95 This amendment to part 95 of the Federal Aviation Regulations (14 CFR part 95) amends, suspends, or revokes IFR altitudes governing the operation of all aircraft in flight over a specified route or any portion of that route, as well as the changeover points (COPs) for Federal airways, jet routes, or direct routes as prescribed in part 95. [Docket No. 30582; Amdt. No. 471] The Rule IFR Altitudes; Miscellaneous Amendments The specified IFR altitudes, when used in conjunction with the prescribed changeover points for those routes, ensure navigation aid coverage that is adequate for safe flight operations and free of frequency interference. The reasons and circumstances that create the need for this amendment involve matters of flight safety and operational efficiency in the National Airspace System, are related to published aeronautical charts that are essential to the user, and provide for the safe and efficient use of the navigable airspace. In addition, those various reasons or circumstances require making this amendment effective before the next scheduled charting and publication date of the flight information to assure its timely availability to the user. The effective date of this amendment reflects those considerations. In view of the close and immediate relationship between these regulatory changes and safety in air commerce, I find that notice and public procedure before adopting this amendment are impracticable and contrary to the public interest and that good cause exists for making the amendment effective in less than 30 days. SUPPLEMENTARY INFORMATION: BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas. DATES: Effective date: 0901 UTC, December 20, 2007.

Pate, Flight Procedure Standards Branch (AMCAFS–420), Flight Technologies and Programs Division, Flight Standards Service, Federal Aviation Administration, Mike Monroney Aeronautical Center, 6500 South MacArthur Blvd., Oklahoma City, SUMMARY: 67571 Conclusion 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. It, therefore—(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. For the same reason, the FAA certifies that this amendment will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 
turbofan engines. That AD currently requires initial and repetitive on-
wing or in-shop inspections of the high pressure/intermediate pressure 
(HP/IP) turbine bearing oil feed tube heat shield. This AD requires the 
same actions but introduces a terminating action to the repetitive 
inspections. This AD results from RR introducing a revised HP/IP 
turbine bearing support structure as terminating action to the 
repetitive inspections of the HP/IP turbine bearing oil feed tube heat 
shield. We are issuing this AD to prevent an uncontained failure of the 
HP turbine disc and damage to the airplane.

DATES: Effective December 14, 2007. The Director of the Federal 
Register previously approved the incorporation by reference of certain 
publications listed in the regulations as of December 19, 2006 (71 FR

SUPPLEMENTARY INFORMATION: On November 3, 2006, the FAA issued AD 2006-
23-11, Amendment 39-14823 (71 FR 66229, November 14, 2006). That AD 
requires initial and repetitive on-wing or in-shop inspections of the 
HP/IP turbine bearing oil feed tube heat shield. That AD was the result 
of a report that a damaged outer heat shield caused fretting of the oil 
feed tubes. That condition, if not corrected, could result in an 
uncontained failure of the HP turbine disc and damage to the airplane.

Actions Since AD 2006-23-11 Was Issued

    Since that AD was issued, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, recently notified us that RR introduced a revised 
HP/IP turbine bearing support structure to terminate the repetitive 
inspections. This AD requires initial and repetitive on-wing or in-shop 
inspections of the HP/IP turbine bearing oil feed tube heat shield, and 
requires revising the HP/IP turbine bearing support structure as 
terminating action to the repetitive inspections in this AD. We are 
issuing this AD to prevent an uncontained failure of the HP turbine 
disc and damage to the airplane.

Relevant Service Information

    We have reviewed and approved the technical contents of RR Service 
Bulletin (SB) No. RB.211-72-F117, Revision 2, dated September 25, 2006, 
RR SB No. RB.211-72-F227, Revision 1, dated October 8, 2007, and RR 
Immediate Operational Request SB No. RB.211-72-F048, Revision 11, dated 
September 9, 2006, that describe procedures for revising the HP/IP 
turbine bearing support structure. EASA classified these SBs as 
mandatory and issued AD 2007-0260 in order to ensure the airworthiness 
of these RR engines in Europe.

Bilateral Airworthiness Agreement

    These engine models are manufactured in the United Kingdom and are 
type certificated for operation in the United States under the 
provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 
21.29) and the applicable bilateral airworthiness agreement. Under this 
bilateral airworthiness agreement, EASA has kept the FAA informed of 
the situation described above. We have examined the findings of EASA, 
reviewed all available information, and determined that AD action is 
necessary for products of this type design that are certificated for 
operation in the United States.

FAA's Determination and Requirements of This AD

    Although no airplanes that are registered in the United States use 
these Trent 768-60, 772-60, and 772B-60 turbofan engines, the 
possibility exists that these engines could be used on airplanes that 
are registered in the United States in the future. The unsafe condition 
described previously is likely to exist or develop on other Trent 768-
60, 772-60, and 772B-60 turbofan engines of the same type design. We 
are issuing this AD to prevent an uncontained failure of the HP turbine 
disc and damage to the airplane. This AD requires initial and 
repetitive on-wing or in-shop inspections of the HP/IP turbine bearing 
oil feed tube heat shield, and requires revising the HP/IP turbine 
bearing support structure as terminating action to the repetitive 
inspections in this AD. You must use the service information described 
previously to perform the actions required by this AD.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this engine 
model, notice and opportunity for public comment before issuing this AD 
are unnecessary. Therefore, a situation exists that allows the 
immediate adoption of this regulation.

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-2006-26052; 
Directorate Identifier 2006-NE-30-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://
www.regulations.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 
FDMS 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).

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is the same as 
the Mail address provided in the ADDRESSES section. Comments will be 
available in the AD docket shortly after receipt.

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;

[[Page 67570]]

    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.
