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: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to all Airbus Model A330-200, A330-300, A340-200, 
and A340-300 series airplanes. That 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 
new AD retains the existing requirements, reduces the applicability of 
the existing AD, and adds terminating actions. For certain airplanes, 
this AD requires upgrading the flight control primary computers. 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.

DATES: This AD becomes effective April 16, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of April 16, 
2008.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2004-03-24, amendment 
39-13468 (69 FR 6549, February 11, 2004). The existing AD applies to 
all Airbus Model A330-200, A330-300, A340-200, and A340-300 series 
airplanes. That NPRM was published in the Federal Register on November 
26, 2007 (72 FR 65897). That NPRM proposed to retain the existing 
requirements, reduce the applicability of the existing AD, and add 
terminating actions.

New Service Information

    Airbus has issued Revision 03 of Airbus Service Bulletins A330-27-
3115 and A340-27-4119, both dated April 22, 2005. In the NPRM, we 
referred to Revision 02 dated December 30, 2003, of those service 
bulletins as the appropriate sources of service information for 
accomplishing certain required actions. Revision 03 of the service 
bulletins updates the operator and aircraft effectivity to show the 
latest information. No additional work is required by this revision of 
the service bulletins. We have changed paragraph (h) of this AD to 
refer to Airbus Service Bulletins A330-27-3115 and A340-27-4119, both 
Revision 03, both dated April 22, 2005. We have also added paragraph 
(h)(3) to the AD to give credit to operators that have done the actions 
previously in accordance with Revision 02 of those service bulletins.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment that has been 
received on the NPRM.

Request To Extend Compliance Time for the Modification

    Air Transport Association (ATA) and one of its members, Northwest 
Airlines (NWA), state that the terminating action specified in the 
proposed AD should be mandated at a maximum of 24 months after the 
effective date for coordination with the aircraft C-check intervals. 
NWA adds that the repetitive tests of the elevator servo-loops will 
ensure continued safe operation until terminating action is 
accomplished.
    We do not agree with the request from ATA and NWA to extend the 
compliance time. In developing an appropriate compliance time for this 
action, we considered the urgency associated with the subject unsafe 
condition, the availability of required parts, and the practical aspect 
of accomplishing the required modification within a period of time that 
corresponds to the normal scheduled maintenance for most affected 
operators. In light of these items, we have determined that a 17-month 
compliance time is appropriate. However, according to the provisions of 
paragraph (p) of the AD, we might approve requests to adjust the 
compliance time if the request includes data that justify that the new 
compliance time would provide an acceptable level of safety.

Conclusion

    We have carefully reviewed the available data, including the 
comment that has been received, and determined that air safety and the 
public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

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 AD.

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

    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 upgrade of 
the flight control primary computers (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 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 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 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

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.

[[Page 13095]]

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 A330-27-3115 or A340-27-4119, both Revision 
03, both including Appendix 01, both dated April 22, 2005, 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.
    (3) Actions done before the effective date of this AD in 
accordance with Airbus Service Bulletin A330-27A3115 or A340-
27A4119, both Revision 02, both including Appendix 01, both dated 
December 30, 2003, are acceptable for compliance with the 
corresponding requirements of this AD.
