Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt 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 proposed AD was prompted by a report that during the evaluation of 
specific engine failure cases 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 proposed AD would require revising 
the Limitations section of the applicable airplane flight manual. We 
are proposing 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: We must receive comments on this proposed AD by February 6, 
2012.

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 2010-0109, dated June 28, 2010 (referred to 
after this as ``the MCAI''), 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 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.

FAA's Determination and Requirements of This Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

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