14 CFR Part 39

[Docket No. FAA-2007-27565; Directorate Identifier 2006-NM-215-AD; 
Amendment 39-15111; AD 2007-13-07]

Airworthiness Directives; Airbus Model A330 and A340 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 certain Airbus Model A330-200, A330-300, A340-
200, and A340-300 series airplanes; and Model A340-541 and -642 
airplanes. That AD currently requires repetitively resetting the 
display units (DUs) for the electronic instrument system (EIS), either 
by switching them off and back on again or by performing a complete 
electrical shutdown of the airplane. This new AD requires installing 
new software, which would end the actions required by the existing AD. 
This new AD also adds additional airplanes that may be placed on the 
U.S. Register in the future. This AD results from an incident in which 
all of the DUs for the EIS went blank simultaneously during flight. We 
are issuing this AD to prevent automatic reset of the DUs for the EIS 
during flight and consequent loss of data from the DUs, which could 
reduce the ability of the flightcrew to control the airplane during 
adverse flight conditions.

DATES: This AD becomes effective July 25, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 25, 2007.
    On September 12, 2005 (70 FR 50166, August 26, 2005), the Director 
of the Federal Register approved the incorporation by reference of 
certain other publications listed in the AD.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2005-17-18, amendment 
39-14239 (70 FR 50166, August 26, 2005). The existing AD applies to 
certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series 
airplanes; and Model A340-541 and -642 airplanes. That NPRM was 
published in the Federal Register on March 15, 2007 (72 FR 12127). That 
NPRM proposed to continue to require repetitively resetting the display 
units for the electronic instrument system, either by switching them 
off and back on again or by performing a complete electrical shutdown 
of the airplane. That NPRM also proposed to require installing new 
software, which would end the actions required by the existing AD. That 
NPRM also proposed to add additional airplanes that may be placed on 
the U.S. Register in the future.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM or 
on the determination of the cost to the public.

New Service Bulletin Revision

    Since we issued the NPRM, we have received Revision 03 of Airbus 
Service Bulletin A330-31-3056, dated November 25, 2004. Airbus issued 
this service bulletin to add non-U.S.-registered airplanes to the 
effectivity. The service bulletin describes procedures for installing 
Thales display system standard L4 or L5 in the electronic instrument 
system 2. No additional work is required for airplanes on which the 
required actions have been done in accordance with Airbus Service 
Bulletin A330-31-3056, Revision 02, dated March 24, 2003, which was 
referred to as the appropriate source of service information for the 
actions specified in the NPRM. We have changed the reference to this 
service bulletin in paragraph (i)(1)(ii) of the AD, added a new 
paragraph (j) of this AD to give credit for actions done before the 
effective date of this AD according to Revision 02 of the service 
bulletin, and redesignated subsequent paragraphs of the AD accordingly.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Clarification of Paragraph Identifiers in Paragraph (h) of This AD

    We have revised paragraph (h) of this AD to include certain 
paragraph identifiers in Table 2 that were unintentionally omitted from 
the NPRM.

Clarification of Applicability

    We unintentionally included only the A340-200 of the Model A340 
airplanes in the subject line on the first page of the NPRM. It should 
have read ``Airbus Model A330 and A340 Airplanes.'' The correct models 
appeared in all other sections of the NPRM. We have corrected the 
subject line in the heading of this final rule.

Conclusion

    We have carefully reviewed the available data 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 
to comply with this AD. The average labor rate per work hour is $80.

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

[[Page 33874]]

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 an incident in which all of the display 
units (DUs) for the EIS went blank simultaneously during flight. We 
are issuing this AD to prevent automatic reset of the DUs for the 
EIS during flight and consequent loss of data from the DUs, which 
could reduce the ability of the flightcrew to control the airplane 
during adverse flight conditions.

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.
