FOR FURTHER INFORMATION CONTACT: Vladimir Ulyanov, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, Washington 98057–3356; telephone (425) 227–1138; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: FCPC Standard W11 (part number (P/N) LA2K2B100GA0000) and —For A330 and A340–200/–300, to take into account the possibility to embody in service a new FCPC3 second electrical power supply equivalent to the production one. This [EASA] AD, which supersedes EASA AD 2008–0010R1 retaining its requirements, is issued to extend the applicability to the newly certified models A330–223F and A330–243F. Federal Aviation Administration Discussion The FAA did not issue corresponding ADs for EASA Airworthiness Directive 2008–0010–E and EASA Airworthiness Directive 2008–0010R1 since it was determined at that time that the FAA Master Minimum Equipment List (MMEL) was an acceptable method for controlling exposure of the U.S. fleet to the safety issue addressed in the EASA ADs. Since that decision was made, the FAA determined that an AD is needed to control dispatch restrictions. In addition, EASA Airworthiness Directive 2010–0109, dated June 28, 2010, added two new Airbus models in the applicability and we are proceeding with this FAA AD in order to address the identified unsafe condition for the U.S. fleet. You may obtain further information by examining the MCAI in the AD docket. This section of the FEDERAL REGISTER contains regulatory documents having general applicability and legal effect, most of which are keyed to and codified in the Code of Federal Regulations, which is published under 50 titles pursuant to 44 U.S.C. 1510. The Code of Federal Regulations is sold by the Superintendent of Documents. Prices of new books are listed in the first FEDERAL REGISTER issue of each week. We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on December 22, 2011 (76 FR 79560). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: 14 CFR Part 39 [Docket No. FAA–2011–1323; Directorate Identifier 2010–NM–212–AD; Amendment 39–17018; AD 2012–08–02] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all Model A330–200 and –300 series airplanes; Model A330–223F and –243F airplanes; and Model A340–200, –300, –500, and –600 series airplanes. This AD was prompted by a report that during the evaluation of engine failures at take-off on Airbus flight simulators, it has been shown that with flight control primary computer (FCPC) 1 inoperative, in worst case scenario when FCPC2 and FCPC3 resets occur during rotation at take off, a transient loss of elevator control associated with a temporary incorrect flight control law reconfiguration could occur. This AD requires revising the Limitations section of the applicable airplane flight manual. We are issuing this AD to prevent movement of the elevators to zero position, which could result in inducing a pitch down movement instead of a pitch up movement needed for lift off, resulting in loss of controllability of the airplane. DATES: This AD becomes effective May 31, 2012. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, mstockstill on DSK4VPTVN1PROD with RULES SUMMARY: VerDate Mar<15>2010 16:14 Apr 25, 2012 Jkt 226001 On A330/A340 aeroplanes, the Flight Control Primary Computer 2 (FCPC2) and FCPC3 are supplied with power from the 2PP bus bar. Electrical transients on the 2PP bus bar occur, in particular during engine n.2 failure on A330 aeroplanes or engine n.3 failure on A340 aeroplanes. Such electrical transients lead to a FCPC2 reset. FCPC3 reset does not occur thanks to the introduction of second electrical power supply to FCPC3 from 1PP bus bar associated to the Electrical Contactor Management Unit (ECMU) standard 5. During the evaluation of specific engine failure cases at take-off on Airbus flight simulators, it has been evidenced that with FCPC1 inoperative, in the worst case, when FCPC2 and FCPC3 resets occur during rotation at take off, a transient loss of elevator control associated with a temporary incorrect flight control law reconfiguration could occur. This condition leads to a movement of the elevators to the zero position, which induces a pitch down movement instead of a pitch up movement needed to lift off. In addition, it leads to a limitation of the pilot control on pitch axis and limits the pilot capacity to counter the pitch down movement during this flight phase, which constitutes an unsafe condition. To prevent such condition, [EASA] Emergency Airworthiness Directive (EAD) 2008–0010–E was issued to prohibit aeroplanes dispatch with FCPC1 inoperative (from GO to NO–GO) for certain aeroplane configurations. For other configurations, dispatch is allowed when the integrity of the FCPC3 second electrical power supply is ensured. EASA AD 2008–0010R1 was issued to: —For A340–500/–600, alleviate the dispatch restriction on aeroplanes fitted with new PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. The commenter, Air Line Pilots Association, International, supports the NPRM (76 FR 79560, December 22, 2011). Explanation of Changes Made to This AD We have made the following changes to this AD: • Redesignated Note 2 to paragraph (g) of the NPRM (76 FR 79560, December 22, 2011) as paragraph (g)(4) of this AD, and redesignated subsequent notes accordingly. • Redesignated paragraph (h) of the NPRM (76 FR 79560, December 22, 2011) as paragraph (h)(1) of this AD. • Redesignated Note 3 to paragraph (h) of the NPRM (76 FR 79560, December 22, 2011) as paragraph (h)(2) of this AD. • Updated paragraph reference in paragraph (h)(2) of this AD. • Updated paragraph references in Note 2 to paragraph (h)(1) of this AD. E:\FR\FM\26APR1.SGM 26APR1 24830 Federal Register / Vol. 77, No. 81 / Thursday, April 26, 2012 / Rules and Regulations Conclusion We 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— except for minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (76 FR 79560, December 22, 2011) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (76 FR 79560, December 22, 2011). Costs of Compliance We estimate that this AD will affect 55 products of U.S. registry. We also estimate that it will take about 1 workhour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $4,675 or $85 per product. 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. mstockstill on DSK4VPTVN1PROD with RULES 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 that this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; VerDate Mar<15>2010 16:14 Apr 25, 2012 Jkt 226001 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska; and 4. 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. Examining the AD Docket You may examine the AD docket on the Internet at https:// 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 the NPRM (76 FR 79560, December 22, 2011), the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2011-1323; Directorate Identifier 2010-NM-212-AD; 
Amendment 39-17018; AD 2012-08-02]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Model A330-200 and -300 series airplanes; Model A330-223F and -243F 
airplanes; and Model A340-200, -300, -500, and -600 series airplanes. 
This AD was prompted by a report that during the evaluation of engine 
failures at take-off on Airbus flight simulators, it has been shown 
that with flight control primary computer (FCPC) 1 inoperative, in 
worst case scenario when FCPC2 and FCPC3 resets occur during rotation 
at take off, a transient loss of elevator control associated with a 
temporary incorrect flight control law reconfiguration could occur. 
This AD requires revising the Limitations section of the applicable 
airplane flight manual. We are issuing this AD to prevent movement of 
the elevators to zero position, which could result in inducing a pitch 
down movement instead of a pitch up movement needed for lift off, 
resulting in loss of controllability of the airplane.

DATES: This AD becomes effective May 31, 2012.

ADDRESSES: You may examine the AD docket on the Internet at https://www.regulations.gov or in person at the U.S. Department of

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on December 22, 2011 
(76 FR 79560). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    On A330/A340 aeroplanes, the Flight Control Primary Computer 2 
(FCPC2) and FCPC3 are supplied with power from the 2PP bus bar. 
Electrical transients on the 2PP bus bar occur, in particular during 
engine n.2 failure on A330 aeroplanes or engine n.3 failure on A340 
aeroplanes. Such electrical transients lead to a FCPC2 reset. FCPC3 
reset does not occur thanks to the introduction of second electrical 
power supply to FCPC3 from 1PP bus bar associated to the Electrical 
Contactor Management Unit (ECMU) standard 5.
    During the evaluation of specific engine failure cases at take-
off on Airbus flight simulators, it has been evidenced that with 
FCPC1 inoperative, in the worst case, when FCPC2 and FCPC3 resets 
occur during rotation at take off, a transient loss of elevator 
control associated with a temporary incorrect flight control law 
reconfiguration could occur. This condition leads to a movement of 
the elevators to the zero position, which induces a pitch down 
movement instead of a pitch up movement needed to lift off. In 
addition, it leads to a limitation of the pilot control on pitch 
axis and limits the pilot capacity to counter the pitch down 
movement during this flight phase, which constitutes an unsafe 
condition.
    To prevent such condition, [EASA] Emergency Airworthiness 
Directive (EAD) 2008-0010-E was issued to prohibit aeroplanes 
dispatch with FCPC1 inoperative (from GO to NO-GO) for certain 
aeroplane configurations. For other configurations, dispatch is 
allowed when the integrity of the FCPC3 second electrical power 
supply is ensured.
    EASA AD 2008-0010R1 was issued to:

--For A340-500/-600, alleviate the dispatch restriction on 
aeroplanes fitted with new FCPC Standard W11 (part number (P/N) 
LA2K2B100GA0000)

and

--For A330 and A340-200/-300, to take into account the possibility 
to embody in service a new FCPC3 second electrical power supply 
equivalent to the production one.

    This [EASA] AD, which supersedes EASA AD 2008-0010R1 retaining 
its requirements, is issued to extend the applicability to the newly 
certified models A330-223F and A330-243F.

    The FAA did not issue corresponding ADs for EASA Airworthiness 
Directive 2008-0010-E and EASA Airworthiness Directive 2008-0010R1 
since it was determined at that time that the FAA Master Minimum 
Equipment List (MMEL) was an acceptable method for controlling exposure 
of the U.S. fleet to the safety issue addressed in the EASA ADs. Since 
that decision was made, the FAA determined that an AD is needed to 
control dispatch restrictions. In addition, EASA Airworthiness 
Directive 2010-0109, dated June 28, 2010, added two new Airbus models 
in the applicability and we are proceeding with this FAA AD in order to 
address the identified unsafe condition for the U.S. fleet. You may 
obtain further information by examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. The commenter, Air Line 
Pilots Association, International, supports the NPRM (76 FR 79560, 
December 22, 2011).

Explanation of Changes Made to This AD

    We have made the following changes to this AD:
     Redesignated Note 2 to paragraph (g) of the NPRM (76 FR 
79560, December 22, 2011) as paragraph (g)(4) of this AD, and 
redesignated subsequent notes accordingly.
     Redesignated paragraph (h) of the NPRM (76 FR 79560, 
December 22, 2011) as paragraph (h)(1) of this AD.

Conclusion

    We 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--except for minor 
editorial changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 79560, December 22, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 79560, December 22, 2011).

Costs of Compliance

    We estimate that this AD will affect 55 products of U.S. registry. 
We also estimate that it will take about 1 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $4,675 or $85 per product.

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 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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

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:

2012-08-02 Airbus: Amendment 39-17018. Docket No. FAA-2011-1323; 
Directorate Identifier 2010-NM-212-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective May 31, 
2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A330-201, -202, -203, -223, -
223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342, 
and -343 airplanes; and Model A340-211, -212, -213, -311, -312, -
313, -541, and -642 airplanes; certificated in any category; all 
serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 27: Flight 
Controls.

(e) Reason

    This AD was prompted by a report that during the evaluation of 
engine failures at take-off on Airbus flight simulators, it has been 
shown that with flight control primary computer (FCPC) 1 
inoperative, in worst case scenario when FCPC2 and FCPC3 resets 
occur during rotation at take off, a transient loss of elevator 
control associated with a temporary incorrect flight control law 
reconfiguration could occur. We are issuing this AD to prevent 
movement of the elevators to zero position, which could result in 
inducing a pitch down movement instead of a pitch up movement needed 
for lift off, resulting in loss of controllability of the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.
