Airworthiness Directives; Airbus Model A330-200, A330-300, A340-
200, and A340-300 Series Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to all Airbus Model A330-200, A330-300, 
A340-200, and A340-300 series airplanes. The existing AD currently 
requires a revision of the airplane flight manual to include procedures 
for a pre-flight elevator check before each flight, repetitive 
inspections for cracks of the attachment lugs of the mode selector 
valve position transducers on the elevator servo controls, and 
corrective actions if necessary. This proposed AD would retain the 
existing requirements, reduce the applicability of the existing AD, and 
add terminating actions. For certain airplanes, this proposed AD would 
require upgrading the flight control primary computers. This proposed 
AD results from cracks of the transducer body at its attachment lugs. 
We are proposing this AD to ensure proper functioning of the elevator 
surfaces, and to prevent cracking of the attachment lugs, which could 
result in partial loss of elevator function and consequent reduced 
controllability of the airplane.

DATES: We must receive comments on this proposed AD by December 26, 
2007.

Discussion

    On February 2, 2004, we issued AD 2004-03-24, amendment 39-13468 
(69 FR 6549, February 11, 2004), for all Airbus Model A330-200, A330-
300, A340-200, and A340-300 series airplanes. That AD requires a 
revision of the airplane flight manual to include procedures for a pre-
flight elevator check before each flight, repetitive inspections for 
cracks of the attachment lugs of the mode selector valve position 
transducers on the elevator servo controls, and corrective actions if 
necessary. That AD resulted from a report of cracks of the transducer 
body at its attachment lugs. We issued that AD to ensure proper 
functioning of the elevator surfaces, and to detect and correct 
cracking of the attachment lugs, which could result in partial loss of 
elevator function and consequent reduced controllability of the 
airplane.

Actions Since Existing AD Was Issued

    The preamble to AD 2004-03-24 explains that we consider the 
requirements ``interim action'' and were considering further 
rulemaking. We now have determined that further rulemaking is indeed 
necessary, and this proposed AD follows from that determination.

Relevant Service Information

    The following service information has been issued:

                                These actions must be done prior to or
                                concurrently with the actions specified
                                in Goodrich Actuation Systems Service
                                Bulletin SC4800-27-16.
------------------------------------------------------------------------

    Airbus Service Bulletin A340-27-4131 refers to Airbus Vendor 
Service Bulletins LA2K0-27-017 and LA2K1-27-009, both dated January 25, 
2005, as additional sources of service information for upgrading the 
FCPCs.
    Airbus Service Bulletins A330-27-3128 and A340-27-4129 refer to 
Goodrich Actuation Systems Service Bulletin SC4800-27-16, Revision 3, 
dated May 19, 2006, as an additional source of service information for 
accomplishing the modification of the four elevator servo controls.
    Accomplishing the actions specified in Airbus Service Bulletin 
A330-27-3128 or A340-27-4129, as applicable, Goodrich Actuation Systems 
Service Bulletin SC4800-27-16, and TRW Service Bulletin SC4800-27-34-
09, if required, would cancel the requirements of AD 2004-03-24. 
Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. The European 
Aviation Safety Agency (EASA), which is the Technical Agent for the 
Member States of the European Community, mandated the service 
information and issued airworthiness directive 2007-0011, dated January 
9, 2007, to ensure the continued airworthiness of these airplanes in 
the European Union.

FAA's Determination and Requirements of the Proposed AD

    These airplanes are manufactured in France 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. As described in FAA 
Order 8100.14A, ``Interim Procedures for Working with the European 
Community on Airworthiness Certification and Continued Airworthiness,'' 
dated August 12, 2005, the EASA has kept the FAA informed of the 
situation described above. We have examined the EASA's findings, 
evaluated all pertinent information, and determined that AD action is 
necessary for airplanes of this type design that are certificated for 
operation in the United States.
    This proposed AD would supersede AD 2004-03-24 and would retain the 
requirements of the existing AD. This proposed AD also would require 
accomplishing the actions specified in service information described 
previously. Accomplishing the actions specified in Airbus Service 
Bulletin A330-27-3128 or A340-27-4129, as applicable, Goodrich 
Actuation Systems Service Bulletin SC4800-27-16, and TRW Service 
Bulletin SC4800-27-34-09, if required, would constitute terminating 
action for the retained requirements of 2004-03-24. This proposed AD 
also would remove airplanes from the applicability of the existing AD.

Changes to Existing AD

    This proposed AD would retain all requirements of AD 2004-03-24. 
Since AD 2004-03-24 was issued, the AD format has been revised, and 
certain paragraphs have been rearranged. As a result, the corresponding 
paragraph identifiers have changed in this proposed AD, as listed in 
the following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                           Corresponding  requirement in

Paragraph (b)...........................  Paragraph (g).
Paragraph (c)...........................  Paragraph (h).
Paragraph (d)...........................  Paragraph (i).
Paragraph (e)...........................  Paragraph (j).
Paragraph (f)...........................  Paragraph (k).
------------------------------------------------------------------------

    AD 2004-03-24 affects all Airbus Model A330-200, A330-300, A340-
200, and A340-300 series airplanes. The applicability of this proposed 
AD would

[[Page 65899]]

exclude those airplanes on which a reinforced mode selector valve has 
been installed, which parallels the applicability of EASA airworthiness 
directive 2007-0011.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
of the affected Model A330-200 and A330-300 series airplanes to comply 
with this proposed AD.

                                                 Estimated Costs

Inspection (new proposed action)            1          $80  $80................           29  $2,320.
----------------------------------------------------------------------------------------------------------------

    Currently, there are no affected Model A340-200 and A340-300 series 
airplanes on the U.S. Register. However, if an affected airplane is 
imported and placed on the U.S. Register in the future, the proposed 
upgrade of the FCPCs would take about 2 work hours, at an average labor 
rate of $80 per work hour. The manufacturer states that it would supply 
required parts to the operators at no cost. Based on these figures, we 
estimate the cost of this proposed AD for Model A340-200 and A340-300 
series airplanes to be $160 per airplane.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

[[Page 65900]]

Unsafe Condition

    (d) This AD results from a report of cracks of the transducer 
body at its attachment lugs. We are issuing this AD to ensure proper 
functioning of the elevator surfaces, and to prevent cracking of the 
attachment lugs, which could result in partial loss of elevator 
function and consequent reduced controllability of the airplane.

Compliance

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

Requirements of AD 2004-03-24

Airplane Flight Manual (AFM) Revision

    (f) Within 30 days after February 26, 2004 (the effective date 
of AD 2004-03-24), revise the Limitations section of the AFM to 
include a pre-flight elevator check, by including the following 
language. This may be done by inserting a copy of this AD into the 
applicable AFM. Thereafter perform the pre-flight check before every 
flight in accordance with the procedure.

Prior or During Taxi

``FLIGHT CONTROLS--CHECK

    1. AT A CONVENIENT STAGE, PRIOR TO OR DURING TAXI, AND BEFORE 
ARMING THE AUTOBRAKE, THE PF SILENTLY APPLIES FULL LONGITUDINAL AND 
LATERAL SIDESTICK DEFLECTION. ON THE F/CTL PAGE, THE PNF CHECKS FULL 
TRAVEL OF ALL ELEVATORS AND ALL AILERONS, AND THE CORRECT DEFLECTION 
AND RETRACTION OF ALL SPOILERS. THE PNF CALLS OUT ``FULL UP,'' 
``FULL DOWN,'' ``NEUTRAL,'' ``FULL LEFT,'' ``FULL RIGHT,'' 
``NEUTRAL,'' AS EACH FULL TRAVEL/NEUTRAL POSITION IS REACHED. THE PF 
SILENTLY CHECKS THAT THE PNF CALLS ARE IN ACCORDANCE WITH THE 
SIDESTICK ORDER.
    NOTE: IN ORDER TO REACH FULL TRAVEL, FULL SIDESTICK MUST BE HELD 
FOR A SUFFICIENT PERIOD OF TIME.
    2. THE PF PRESSES THE PEDAL DISC PUSHBUTTON ON THE NOSEWHEEL 
TILLER, AND SILENTLY APPLIES FULL LEFT RUDDER, FULL RIGHT RUDDER, 
AND NEUTRAL. THE PNF CALLS OUT ``FULL LEFT,'' ``FULL RIGHT,'' 
``NEUTRAL,'' AS EACH FULL TRAVEL/NEUTRAL POSITION IS REACHED.
    3. THE PNF APPLIES FULL LONGITUDINAL AND LATERAL SIDESTICK 
DEFLECTION, AND SILENTLY CHECKS FULL TRAVEL AND CORRECT SENSE OF ALL 
ELEVATORS AND ALL AILERONS, AND CORRECT DEFLECTION AND RETRACTION OF 
ALL SPOILERS, ON THE ECAM F/CTL PAGE.''

    Note 1: Full and complete elevator travel (position commanded) 
can be verified on the ECAM Flight Control Page. A determination of 
``correct sense'' should include verification that there is complete 
and full motion of the sidesticks without binding.

    (g) If any pre-flight check required by paragraph (f) of this AD 
reveals improper function of the elevator: Before further flight, 
perform the inspections required by paragraph (h) of this AD.

Inspections

    (h) At the applicable time specified in paragraph (h)(1) or 
(h)(2) of this AD, except as required by paragraph (g) of this AD: 
Perform a dye penetrant inspection of the attachment lugs of the 
mode selector valve position transducers on each elevator servo 
control installed at damping positions 3CS1 and 3CS2. Do the 
inspection in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A330-27A3115 or A340-27A4119, both Revision 
02, both dated December 30, 2003, as applicable (in paragraphs (h) 
through (k) of this AD, referred to as ``the service bulletin''). An 
inspection that is done before February 26, 2004, is acceptable for 
compliance with the initial inspection requirement of this 
paragraph, if the inspection is done in accordance with any of the 
following Airbus All Operators Telexes (AOTs): AOT A330-27A3115 or 
A340-27A4119, dated September 11, 2003, or Revision 01 of each AOT 
dated September 25, 2003; as applicable. Repeat the inspection 
thereafter at intervals not to exceed 350 flight cycles, until the 
applicable actions required by paragraphs (m) and (n) of this AD 
have been done.
    (1) If the age of the servo control from the date of its first 
installation on the airplane can be positively determined: Do the 
inspection before the accumulation of 1,000 total flight cycles on 
the elevator servo control, or within 350 flight cycles on the servo 
control after February 26, 2004, whichever occurs later.
    (2) If the age of the servo control from the date of its first 
installation on the airplane cannot be positively determined, do the 
inspection within 350 flight cycles on the servo control after 
February 26, 2004.

    Note 2: The service bulletin refers to Goodrich Actuation 
Systems Inspection Service Bulletin SC4800-27-13 as an additional 
source of service information for the inspection.

Corrective Actions

    (i) If any crack is found during any inspection required by 
paragraph (h) of this AD: Before further flight, replace either the 
transducer or servo control with a new part, in accordance with the 
service bulletin.

Reporting Requirement
