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 2010–0271, dated December 22, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: When there are significant differences between all airspeed sources, the flight controls of an Airbus A330 or A340 aeroplane will revert to alternate law, the autopilot (AP) and the auto-thrust (A/THR) automatically disconnect, and the Flight Directors (FD) bars are automatically removed.

E:\FR\FM\25JAR1.SGM 25JAR1 4220 Federal Register / Vol. 76, No. 16 / Tuesday, January 25, 2011 / Rules and Regulations In order to prevent such event which may, under specific circumstances, constitute an unsafe condition, this AD requires an amendment of the Flight Manual to ensure that flight crews apply the appropriate operational procedure. The unsafe condition is the potential for abrupt pitch command which may lead to unexpected maneuvers of the airplane and cause injuries of the crew and passengers, as well as reduced controllability of the airplane and increased pilot workload. Required actions include revising the limitations and abnormal sections of the airplane flight manual to include a procedure for when the autopilot and auto-thrust are automatically disconnected and flight controls have reverted to alternate law.

Relevant Service Information Airbus has issued A330/A340 Temporary Revisions TR149 and TR150, both Issue 1.0, both dated December 20, 2010, to the Airbus A330/A340 Airplane Flight Manual. 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. srobinson on DSKHWCL6B1PROD 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. VerDate Mar<15>2010 16:23 Jan 24, 2011 Jkt 223001 FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because of the potential for abrupt pitch command which may lead to unexpected maneuvers of the airplane and cause injuries of the crew and passengers, as well as reduced controllability of the airplane, and increased pilot workload. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. 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–2011–0029; Directorate Identifier 2010–NM–279– 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 PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 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.

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:

    When there are significant differences between all airspeed 
sources, the flight controls of an Airbus A330 or A340 aeroplane 
will revert to alternate law, the autopilot (AP) and the auto-thrust 
(A/THR) automatically disconnect, and the Flight Directors (FD) bars 
are automatically removed.
    It has been identified that, after such an event, if two 
airspeed sources become similar while still erroneous, the flight 
guidance computers will:

--Display FD bars again, and
--Enable autopilot and auto-thrust re-engagement

    However, in some cases, the autopilot orders may be 
inappropriate, such as possible abrupt pitch command.
* * * * *
The unsafe condition is the potential for abrupt pitch command which 
may lead to unexpected maneuvers of the airplane and cause injuries of 
the crew and passengers, as well as reduced controllability of the 
airplane, and increased pilot workload. This AD requires actions that 
are intended to address the unsafe condition described in the MCAI.

DATES: This AD becomes effective February 9, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of February 9, 
2011.
    We must receive comments on this AD by March 11, 2011.

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 2010-0271, dated December 22, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    When there are significant differences between all airspeed 
sources, the flight controls of an Airbus A330 or A340 aeroplane 
will revert to alternate law, the autopilot (AP) and the auto-thrust 
(A/THR) automatically disconnect, and the Flight Directors (FD) bars 
are automatically removed.
    It has been identified that, after such an event, if two 
airspeed sources become similar while still erroneous, the flight 
guidance computers will:

--Display FD bars again, and
--Enable autopilot and auto-thrust re-engagement

    However, in some cases, the autopilot orders may be 
inappropriate, such as possible abrupt pitch command.

[[Page 4220]]

    In order to prevent such event which may, under specific 
circumstances, constitute an unsafe condition, this AD requires an 
amendment of the Flight Manual to ensure that flight crews apply the 
appropriate operational procedure.

The unsafe condition is the potential for abrupt pitch command which 
may lead to unexpected maneuvers of the airplane and cause injuries of 
the crew and passengers, as well as reduced controllability of the 
airplane and increased pilot workload. Required actions include 
revising the limitations and abnormal sections of the airplane flight 
manual to include a procedure for when the autopilot and auto-thrust 
are automatically disconnected and flight controls have reverted to 
alternate law. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    Airbus has issued A330/A340 Temporary Revisions TR149 and TR150, 
both Issue 1.0, both dated December 20, 2010, to the Airbus A330/A340 
Airplane Flight Manual. 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.

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

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because of 
the potential for abrupt pitch command which may lead to unexpected 
maneuvers of the airplane and cause injuries of the crew and 
passengers, as well as reduced controllability of the airplane, and 
increased pilot workload. Therefore, we determined that notice and 
opportunity for public comment before issuing this AD are impracticable 
and that good cause exists for making this amendment effective in fewer

    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-2011-0029; Directorate 
Identifier 2010-NM-279-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.

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

2011-02-09 Airbus: Amendment 39-16583. Docket No. FAA-2011-0029; 
Directorate Identifier 2010-NM-279-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective February 
9, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-201, -202, -203, -223, 
-223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342,

Subject

    (d) Air Transport Association (ATA) of America Code 22: Auto 
Flight.

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:
    When there are significant differences between all airspeed 
sources, the flight controls of an Airbus A330 or A340 aeroplane 
will revert to alternate law, the autopilot (AP) and the auto-thrust 
(A/THR) automatically disconnect, and the Flight Directors (FD) bars 
are automatically removed.
    It has been identified that, after such an event, if two 
airspeed sources become similar while still erroneous, the flight 
guidance computers will:

--Display FD bars again, and
--Enable autopilot and auto-thrust re-engagement

    However, in some cases, the autopilot orders may be 
inappropriate, such as possible abrupt pitch command.
* * * * *
The unsafe condition is the potential for abrupt pitch command which 
may lead to unexpected maneuvers of the airplane and cause injuries 
of the crew and passengers, as well as reduced controllability of 
the airplane and increased pilot workload.

Compliance

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

Actions

    (g) Within 15 days after the effective date of this AD, do the 
actions in paragraph (g)(1) or (g)(2) of this AD.
    (1) Revise the Limitations and Abnormal Sections of the Airbus 
A330/A340 Airplane Flight Manual (AFM) to include the following 
statement and operate the airplane according to these limitations 
and procedures. This may be done by inserting a copy of this AD in 
the AFM.
    ``PROCEDURE:
    When autopilot and auto-thrust are automatically disconnected 
and flight controls have reverted to alternate law:

--Do not engage the AP and the A/THR, even if FD bars have 
reappeared
--Do not follow the FD orders
--ALL SPEED INDICATIONS--X-CHECK

     If unreliable speed indication is suspected:

--UNRELIABLE SPEED INDIC/ADR CHECK PROC--APPLY

     If at least two ADRs provide reliable speed indication 
for at least 30 seconds, and the aircraft is stablised on the 
intended path:
    AP/FD and A/THR--As required''

    Note 1: When a statement identical to that in paragraph (g)(1) 
of this AD has been included in the general revisions of the 
Limitations and Abnormal Sections of the AFM, the general revisions 
may be inserted into the AFM, and the copy of this AD may be removed 
from the AFM.

    (2) Revise the Limitations and Abnormal Sections of the Airbus 
A330/A340 Airplane Flight Manual (AFM) to include the information in 
Airbus A330/A340 Temporary Revision (TR) TR149 (for Model A330 
airplanes) or TR150 (for Model A340-200 and -300 series airplanes), 
both Issue 1.0, both dated December 20, 2010. These TRs introduce 
procedures for operation of the auto pilot and auto-thrust 
disconnect. Operate the airplane according to the limitations and 
procedures in the TRs.

    Note 2: This may be done by inserting copies of Airbus A330/A340 
TR TR149 or TR150, both Issue 1.0, both dated December 20, 2010; as 
applicable; in the Airbus A330/A340 AFM. When these TRs have been 
included in general revisions of the AFM, the general revisions may 
be inserted in the AFM, and the TRs may be removed.

FAA AD Differences

    Note 3: This AD differs from the MCAI and/or service information 
as follows: No Differences.
