Airworthiness Directives; Airbus Model A330 and A340 Series 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Model A330 and A340 series airplanes. This AD requires 
revising the airplane flight manual to provide procedures for the 
flightcrew to follow in the event of the loss of all liquid crystal 
display (LCD) units on airplanes equipped with the EIS2 standard of 
electronic instrument system. This AD is prompted by reports of the 
brief but total loss of all LCD units during cruise on airplanes 
equipped with the EIS2 standard of electronic instrument system. We are 
issuing this AD to provide procedures to the flightcrew to restore 
operation of these LCD units and prevent prolonged loss of critical 
flight information to the flightcrew and the consequent reduced ability 
of the flightcrew to control the airplane during adverse flight 
conditions.

DATES: Effective October 15, 2004.
    The incorporation by reference of certain publications listed in 
the AD is approved by the Director of the Federal Register as of 
October 15, 2004.
    We must receive comments on this AD by November 29, 2004.

Docket Management System (DMS)

    The FAA has implemented new procedures for maintaining AD dockets 
electronically. As of May 17, 2004, new AD actions are posted on DMS 
and assigned a docket number. We track each action and assign a 
corresponding directorate identifier. The DMS AD docket number is in 
the form ``Docket No. FAA-2004-99999.'' The Transport Airplane 
Directorate identifier is in the form ``Directorate Identifier 2004-NM-
999-AD.'' Each DMS AD docket also lists the directorate identifier 
(``Old

[[Page 58254]]

Docket Number'') as a cross-reference for searching purposes.

SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile 
(DGAC), which is the airworthiness authority for France, notified the 
FAA that an unsafe condition may exist on certain Airbus Model A330 and 
A340 series airplanes. The DGAC advises that there have been several 
reports of total loss of all six liquid crystal display (LCD) units for 
the electronic instrument system (EIS) of standard EIS2 during cruise 
for a short period of time. The flightcrew used the standby 
instruments, and the LCD units were eventually recovered. Subsequent 
investigation revealed that the three display management computers had 
received erroneous data from one LCD unit. Loss of all LCD units, if 
not corrected, could result in loss of critical flight information and 
the reduced ability of the flightcrew to control the airplane during 
adverse operating conditions.

Relevant Service Information

    Airbus has issued the following temporary revisions (TRs) to the 
Airbus A330 and A340 airplane flight manuals (AFMs), as applicable:

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

    The TRs provide procedures for the flightcrew to follow in the 
event of the loss of all LCD units on airplanes equipped with the EIS2 
standard of electronic instrument system. The DGAC mandated 
incorporation of the TRs and issued French airworthiness directive F-
2004-117, dated July 21, 2004, to ensure the continued airworthiness of 
these airplanes in France.

FAA's Determination and Requirements of This AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
Sec.  21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the 
applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for products of this type design that are certificated for 
operation in the United States.
    Therefore, we are issuing this AD to provide procedures to the 
flightcrew to restore operation of these LCD units and prevent 
prolonged loss of critical flight information to the flightcrew and the 
consequent reduced ability of the flightcrew to control the airplane 
during adverse flight conditions. This AD requires revising the AFM to 
incorporate the TRs described previously.

Differences Between FAA and DGAC Airworthiness Directives

    The DGAC airworthiness directive mandates changes to the master 
minimum equipment list (MMEL). But this (FAA) AD will not mandate those 
MMEL changes because the limits imposed by the FAA-approved MMEL meet 
or exceed those mandated by the French airworthiness directive.
    Although the DGAC airworthiness directive mandates the immediate 
incorporation of the TRs' operational limitations, this (FAA) AD would 
allow up to 10 days for compliance. We find that a 10-day compliance 
time will provide the time necessary for operators to accomplish the 
requirements of this AD without adversely affecting safety.

Interim Action

    We consider this AD interim action. If final action is later 
identified, we may consider further rulemaking then.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD; therefore, providing notice and opportunity for public comment 
before the AD is issued is impracticable, and good cause exists to make 
this AD effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any relevant written 
data, views, or arguments regarding this AD. Send your comments to an 
address listed under ADDRESSES. Include ``Docket No. FAA-2004-19184; 
Directorate Identifier 2004-NM-159-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD. We will consider 
all comments received by the closing date and may amend the AD in light 
of those comments.
    We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact with FAA

[[Page 58255]]

personnel concerning this AD. Using the search function of our docket 
Web site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.). 
You can review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477-78), or you can visit 
http://dms.dot.gov.
    We are reviewing the writing style we currently use in regulatory 
documents. We are interested in your comments on whether the style of 
this document is clear, and your suggestions to improve the clarity of 
our communications with you. You can get more information about plain 
language at http://www/faa.gov/language and http://www.plainlanguage.gov.

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 the 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 AD. See the ADDRESSES section for a location to 
examine the regulatory evaluation.
