Federal Aviation Administration, DOT.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes, that currently requires an inspection of the parking brake operated valve (PBOV) of the main landing gear to identify the part and serial numbers, and follow-on actions if necessary. That AD also provides for optional terminating action for the requirements of that AD. This amendment requires accomplishment of the previously optional terminating action. The actions specified by this AD are intended to prevent leakage of the PBOV and consequent failure of the “blue” hydraulic system and alternate parking brake and emergency braking systems, which could affect elements of the hydraulics for flaps, stabilizer, certain spoilers, elevator, rudder, and aileron. This action is intended to address the identified unsafe condition.
Effective February 6, 2003.
The incorporation by reference of the publications listed in the regulations was approved previously by the Director of the Federal Register as of May 8, 2002 (67 FR 19650, April 23, 2002).
The service information referenced in this AD may be obtained from Airbus Industrie, 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.Start Further Info

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 2002-08-12, amendment 39-12720 (67 FR 19650, April 23, 2002), which is applicable to certain Airbus Model A330 and A340 series airplanes, was published in the Federal Register on August 16, 2002 (67 FR 53523). The action proposed to continue to require an inspection of the parking brake operated valve (PBOV) of the main landing gear to identify the part and serial numbers, and follow-on actions if necessary. That action also proposed to require accomplishment of the previously optional terminating action.
Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were submitted in response to the proposal or the FAA's determination of the cost to the public.
The FAA has determined that air safety and the public interest require the adoption of the rule as proposed.
There are approximately 9 airplanes of U.S. registry that are affected by this AD.
The inspection that is currently required by AD 2002-08-12, and retained in this AD, takes approximately 2 work hours per airplane to accomplish, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of the currently required actions is estimated to be $120 per airplane.
The new modification/replacement required by this AD will take approximately 4 work hours per airplane to accomplish, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of the new requirements of this AD on U.S. operators is estimated to be $2,160, or $240 per airplane.
The cost impact figures discussed above are 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.

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 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 ADDRESSES.Start List of Subjects
