ACTION: Final rule.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to all Airbus Model A319, A320, and A321 series 
airplanes. That AD currently requires identification of the part number 
and serial number of the parking brake operated valve (PBOV); and, if 
necessary, inspection of the PBOV, including a functional check of the 
PBOV, and follow-on and corrective actions. That AD also provides for 
an optional terminating action for the requirements of that AD. This 
new action mandates the previously optional terminating action, which 
terminates the inspection requirements of the previous AD. The actions 
specified by this AD are intended to prevent leakage of hydraulic fluid 
from the PBOV, which could cause the loss of the parking brake 
accumulator, and render the alternate braking system and the parking/
emergency braking system inoperative, as well as causing the loss of 
function of the yellow hydraulic system (which provides all or part of 
the hydraulics for the elevator, rudder, aileron, flaps, stabilizer, 
yaw damper, pitch and yaw feel systems and autopilot, and certain 
spoilers).

DATES: Effective June 2, 2004.
    The incorporation by reference of Airbus Service Bulletin A320-
32A1233, Revision 01, excluding Appendix 01, dated October 1, 2001, as 
listed in the regulations, is approved by the Director of the Federal 
Register as of June 2, 2004.
    The incorporation by reference of Airbus Service Bulletin A320-
32A1233, including Appendix 01, dated August 16, 2001, as listed in the 
regulations, was approved previously by the Director of the Federal 
Register as of May 8, 2002 (67 FR 19652, April 23, 2002).

ADDRESSES: The service information referenced in this AD may be 
obtained from Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac 
Cedex, France. This information may be examined at the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, Rules Docket, 
1601 Lind Avenue, SW., Renton, Washington; or at the Office of the 
Federal Register, 800 North Capitol Street, NW., suite 700, Washington, 
DC.

227-2125; fax (425) 227-1149.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 2002-08-13, 
amendment 39-12721 (67 FR 19652, April 23, 2002), which is applicable 
to all Airbus Model A319, A320, and A321 series airplanes, was 
published in the Federal Register on January 26, 2004 (69 FR 3535). The 
action proposed to continue to require identification of the part 
number and serial number of the parking brake operated valve (PBOV); 
and, if necessary, inspection of the PBOV, including a functional check 
of the PBOV, and follow-on and corrective actions. The action also 
proposed to mandate the optional terminating action, which would 
terminate the inspection requirements of the previous AD.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the single comment received.

Request To Change Applicability

    One commenter, the manufacturer, requests that the FAA change the 
applicability statement to designate the part number and serial numbers 
of the affected PBOV(s). The commenter states no rationale for its 
request.
    We do not agree that the change requested by the commenter is 
necessary. The applicability of this AD (``All Model A319, A320, and 
A321 series airplanes, certificated in any category'') is identical to 
that in AD 2002-08-13. This AD restates certain requirements of that 
AD, including the requirement to identify the part number and serial 
number of the PBOV to determine whether the PBOV is affected. Since 
this action is restated in this AD, it would be redundant to state the 
part number and serial numbers of the affected PBOV(s) in the 
applicability statement. Also, the requirement in paragraph (e) of this 
new AD specifies repair or replacement of PBOVs having the affected 
part number and serial numbers. We find no justification to alter the 
requirements of this AD. Therefore, we have not changed the final rule 
in this matter.

Changes Made to This Final Rule

    Operators should note that Airbus Service Bulletin A320-32A1233, 
including Appendix 01, dated August 16, 2001, listed in paragraph (a) 
of this AD, was previously incorporated by reference in AD 2002-08-13, 
amendment 39-12721 (67 FR 19652, April 23, 2002). The citation for that 
service bulletin ``included'' Appendix 01, which consisted of an 
inspection report. According to the Office of the Federal Register's 
guidelines for materials previously incorporated by reference, we must 
restate the document citation exactly as it appeared in the original 
incorporation. However, it was not our intent to require accomplishment 
of that report.
    Operators should note that we have added new paragraph (h) to this 
final rule (and reidentified subsequent paragraphs) to clarify that 
submission of the inspection report contained in Appendix 01 of the 
referenced service bulletins is not required.

Conclusion

    After careful review of the available data, including the comment 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule with the change described 
previously. The FAA has determined that this change will neither 
increase the economic burden on any operator nor increase the scope of 
the AD.

Cost Impact

    There are approximately 333 airplanes of U.S. registry that will be 
affected by this AD. The new requirements of this AD add no additional 
economic burden. The current costs for this AD are as follows:
    The actions that are currently required by AD 2002-08-13, and that 
are also required by this AD, take approximately 2 work hours per 
airplane to accomplish, at an average labor rate of $65 per work hour. 
Based on these figures, the cost impact of the currently required 
actions on U.S. operators is estimated to be $43,290 or $130 per 
airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the requirements of this AD 
action, and that no operator would accomplish those actions in the 
future if this AD were not adopted. The cost impact figures discussed 
in AD rulemaking actions represent only the time necessary to perform 
the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    The regulations adopted herein 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

[[Page 23097]]

levels of government. Therefore, it is determined that this final rule 
does not have federalism implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption
