It is not a rule of general applicability. Federal Aviation Administration 14 CFR Part 39 List of Subjects in 14 CFR Part 25 [Docket No. FAA–2009–1109; Directorate Identifier 2009–NM–068–AD; Amendment 39–16123; AD 2009–25–04] Aircraft, Aviation safety, Reporting and recordkeeping requirements. RIN 2120–AA64 The authority citation for these special conditions is as follows: Airworthiness Directives; Airbus Model A330–243 Airplanes and Model A330– 341, –342, and –343 Airplanes Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704. The Proposed Special Condition Accordingly, the Federal Aviation Administration (FAA) proposes the following special condition as part of the type certification basis for Dassault Aviation Falcon Model 2000EX airplanes. ■ AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; request for comments. Landing Pitchover Condition A landing pitchover condition must be addressed that takes into account the effect of the autobrake system. The airplane is assumed to be at the design maximum landing weight, or at the maximum weight allowed with the autobrake system on. The airplane is assumed to land in a tail-down attitude and at the speeds defined in § 25.481. Following main gear contact, the airplane is assumed to rotate about the main gear wheels at the highest pitch rate allowed by the autobrake system. This is considered a limit load condition from which ultimate loads must also be determined. Loads must be determined for critical fuel and payload distributions and centers of gravity. Nose gear loads, as well as airframe loads, must be determined. The airplane must support these loads as described in § 25.305. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 772 B engines experienced an engine#1 uncontained multiple turbine blade failure. Investigations have shown that High Pressure/Intermediate Pressure (HP/IP) oil vent tubes are prone to be affected by carbon deposit or to be damaged by their outer heat shields leading to a fire inside or outside the vent tube and resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT disc overspeed. If not corrected, IPT disc overspeed could lead to an uncontained engine failure, i.e. multiple turbine blade failure or HP/IP turbine disc burst, which would constitute an unsafe condition.

SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2009–0075, dated April 6, 2009 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 772 B engines experienced an engine#1 uncontained multiple turbine blade failure. Investigations have shown that High Pressure/Intermediate Pressure (HP/IP) oil vent tubes are prone to be affected by carbon deposit or to be damaged by their outer heat shields leading to a fire inside or outside the vent tube and resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT disc overspeed. If not corrected, IPT disc overspeed could lead to an uncontained engine failure, i.e. multiple turbine blade failure or HP/IP turbine disc burst, which would constitute an unsafe condition. In order to protect IPT from overspeed, EASA AD 2008–0101 required to activate Intermediate Pressure Turbine Overspeed (IPTOS) protection function by Data Entry Plug (DEP) reprogramming, which consists in limiting the IPT speed (Engine Thrust) when overheat is detected in IPT, for all A330 aeroplanes fitted with RR Trent 700 engines and equipped with Multi Mode Receivers. Original issue of AD 2008–0101 had a limited applicability due to Flight Warning Computer compatibility issue with aircraft not equipped with Multi Mode Receivers. Airbus has now developed a new Flight E:\FR\FM\10DER1.SGM 10DER1 Federal Register / Vol. 74, No. 236 / Thursday, December 10, 2009 / Rules and Regulations Warning Computer standard T2 whose embodiment is also possible on A330 aeroplane fitted with RR Trent 700 engines not equipped with Multi Mode Receivers. For the above described reasons, this AD retains the requirement of EASA AD 2008– 0101, which is superseded, and extends the applicability to all A330 aeroplanes fitted with RR Trent 700 engines. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Mandatory Service Bulletin A330–73–3049, Revision 01, dated November 13, 2008. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future. mstockstill on DSKH9S0YB1PROD with RULES Differences Between the AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a note within the AD. FAA’s Determination of the Effective Date Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. VerDate Nov<24>2008 16:49 Dec 09, 2009 Jkt 220001 Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2009–1109; Directorate Identifier 2009–NM–068– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. 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 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 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 PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 65397 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 regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: ■ PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: ■ 2009–25–04 Airbus: Amendment 39–16123. Docket No. FAA–2009–1109; Directorate Identifier 2009–NM–068–AD. Effective Date (a) This airworthiness directive (AD) becomes effective December 28, 2009. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A330– 243, –341,–342, and –343 airplanes, all manufacturing serial numbers (MSN), except those on which Airbus Modification 56722 has been embodied in production. Subject (d) Air Transport Association (ATA) of America Code 73: Engine fuel and control. Reason (e) The mandatory continued airworthiness information (MCAI) states: An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 772 B engines experienced an engine #1 uncontained multiple turbine blade failure. Investigations have shown that High Pressure/Intermediate Pressure (HP/IP) oil vent tubes are prone to be affected by carbon deposit or to be damaged by their outer heat shields leading to a fire inside or outside the vent tube and resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT disc overspeed. If not corrected, IPT disc overspeed could lead to an uncontained engine failure, i.e. multiple turbine blade failure or HP/IP turbine disc burst, which would constitute an unsafe condition. In order to protect IPT from overspeed, EASA AD 2008–0101 required to activate E:\FR\FM\10DER1.SGM 10DER1 65398 Federal Register / Vol. 74, No. 236 / Thursday, December 10, 2009 / Rules and Regulations Intermediate Pressure Turbine Overspeed (IPTOS) protection function by Data Entry Plug (DEP) reprogramming, which consists in limiting the IPT speed (Engine Thrust) when overheat is detected in IPT, for all A330 aeroplanes fitted with RR Trent 700 engines and equipped with Multi Mode Receivers. Original issue of AD 2008–0101 had a limited applicability due to Flight Warning Computer compatibility issue with aircraft not equipped with Multi Mode Receivers. Airbus has now developed a new Flight Warning Computer standard T2 whose embodiment is also possible on A330 aeroplane fitted with RR Trent 700 engines not equipped with Multi Mode Receivers. For the above described reasons, this AD retains the requirement of EASA AD 2008– 0101, which is superseded, and extends the applicability to all A330 aeroplanes fitted with RR Trent 700 engines. Actions and Compliance (f) Unless already done, do the following actions: Within 12 months after the effective date of this AD, do the actions specified in paragraph (f)(1) of this AD. (1) Reprogram the data entry plug on both engines to activate the intermediate pressure turbine overspeed protection function, including doing applicable revisions of the Airplane Flight Manual (AFM), in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330–73–3049, Revision 01, dated November 13, 2008. Note 1: IPTOS function activation has the following operational consequences: Modification of the AFM and the flightcrew operating manual (FCOM). Accomplishment of the actions specified in Airbus Mandatory Service Bulletin A330–73–3049, Revision 01, dated November 13, 2008 (Airbus Modification 56722), cancels Airbus A330 AFM Supplement 6.03.08, dated June 2, 2006; and Volumes 1 and 3 (1.70.20, 1.70.95, and 3.02.70) of the Airbus A330 FCOM have been modified.

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 
772 B engines experienced an engine1 uncontained multiple 
turbine blade failure. Investigations have shown that High Pressure/
Intermediate Pressure (HP/IP) oil vent tubes are prone to be 
affected by carbon deposit or to be damaged by their outer heat 
shields leading to a fire inside or outside the vent tube and 
resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT 
disc overspeed.
    If not corrected, IPT disc overspeed could lead to an 
uncontained engine failure, i.e. multiple turbine blade failure or 
HP/IP turbine disc burst, which would constitute an unsafe 
condition.
* * * * *
This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2009-0075, dated April 6, 2009 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 
772 B engines experienced an engine1 uncontained multiple 
turbine blade failure. Investigations have shown that High Pressure/
Intermediate Pressure (HP/IP) oil vent tubes are prone to be 
affected by carbon deposit or to be damaged by their outer heat 
shields leading to a fire inside or outside the vent tube and 
resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT 
disc overspeed.
    If not corrected, IPT disc overspeed could lead to an 
uncontained engine failure, i.e. multiple turbine blade failure or 
HP/IP turbine disc burst, which would constitute an unsafe 
condition.
    In order to protect IPT from overspeed, EASA AD 2008-0101 
required to activate Intermediate Pressure Turbine Overspeed (IPTOS) 
protection function by Data Entry Plug (DEP) reprogramming, which 
consists in limiting the IPT speed (Engine Thrust) when overheat is 
detected in IPT, for all A330 aeroplanes fitted with RR Trent 700 
engines and equipped with Multi Mode Receivers.
    Original issue of AD 2008-0101 had a limited applicability due 
to Flight Warning Computer compatibility issue with aircraft not 
equipped with Multi Mode Receivers. Airbus has now developed a new 
Flight

[[Page 65397]]

Warning Computer standard T2 whose embodiment is also possible on 
A330 aeroplane fitted with RR Trent 700 engines not equipped with 
Multi Mode Receivers.
    For the above described reasons, this AD retains the requirement 
of EASA AD 2008-0101, which is superseded, and extends the 
applicability to all A330 aeroplanes fitted with RR Trent 700 
engines.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A330-73-3049, Revision 
01, dated November 13, 2008. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

Differences Between the AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a note within the AD.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2009-1109; Directorate 
Identifier 2009-NM-068-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 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 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2009-25-04 Airbus: Amendment 39-16123. Docket No. FAA-2009-1109; 
Directorate Identifier 2009-NM-068-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
28, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-243, -341,-342, and -
343 airplanes, all manufacturing serial numbers (MSN), except those 
on which Airbus Modification 56722 has been embodied in production.

Subject

    (d) Air Transport Association (ATA) of America Code 73: Engine 
fuel and control.

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:
    An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent 
772 B engines experienced an engine 1 uncontained multiple 
turbine blade failure. Investigations have shown that High Pressure/
Intermediate Pressure (HP/IP) oil vent tubes are prone to be 
affected by carbon deposit or to be damaged by their outer heat 
shields leading to a fire inside or outside the vent tube and 
resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT 
disc overspeed.
    If not corrected, IPT disc overspeed could lead to an 
uncontained engine failure, i.e. multiple turbine blade failure or 
HP/IP turbine disc burst, which would constitute an unsafe 
condition.
    In order to protect IPT from overspeed, EASA AD 2008-0101 
required to activate

[[Page 65398]]

Intermediate Pressure Turbine Overspeed (IPTOS) protection function 
by Data Entry Plug (DEP) reprogramming, which consists in limiting 
the IPT speed (Engine Thrust) when overheat is detected in IPT, for 
all A330 aeroplanes fitted with RR Trent 700 engines and equipped 
with Multi Mode Receivers.
    Original issue of AD 2008-0101 had a limited applicability due 
to Flight Warning Computer compatibility issue with aircraft not 
equipped with Multi Mode Receivers. Airbus has now developed a new 
Flight Warning Computer standard T2 whose embodiment is also 
possible on A330 aeroplane fitted with RR Trent 700 engines not 
equipped with Multi Mode Receivers.
    For the above described reasons, this AD retains the requirement 
of EASA AD 2008-0101, which is superseded, and extends the 
applicability to all A330 aeroplanes fitted with RR Trent 700 
engines.

Actions and Compliance

    (f) Unless already done, do the following actions: Within 12 
months after the effective date of this AD, do the actions specified 
in paragraph (f)(1) of this AD.
    (1) Reprogram the data entry plug on both engines to activate 
the intermediate pressure turbine overspeed protection function, 
including doing applicable revisions of the Airplane Flight Manual 
(AFM), in accordance with the Accomplishment Instructions of Airbus 
Mandatory Service Bulletin A330-73-3049, Revision 01, dated November 
13, 2008.

    Note 1: IPTOS function activation has the following operational 
consequences: Modification of the AFM and the flightcrew operating 
manual (FCOM). Accomplishment of the actions specified in Airbus 
Mandatory Service Bulletin A330-73-3049, Revision 01, dated November 
13, 2008 (Airbus Modification 56722), cancels Airbus A330 AFM 
Supplement 6.03.08, dated June 2, 2006; and Volumes 1 and 3 
(1.70.20, 1.70.95, and 3.02.70) of the Airbus A330 FCOM have been 
modified.

    (2) Actions accomplished before the effective date of this AD in 
accordance with Airbus Mandatory Service Bulletin A330-73-3049, 
dated November 14, 2007, are considered acceptable for compliance 
with the corresponding action specified in paragraph (f)(1) of this 
AD.
