AD 2005-04-11

The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A300 B2 and B4, A300-600, and A310 series airplanes. That AD currently requires identification of the part number and serial number of the parking brake operated valve (PBOV); and, if necessary, inspections of the PBOV, including a functional check of the PBOV, and follow-on and corrective actions. That AD also provides for optional terminating action for the requirements of that AD. This new AD requires modification of all affected PBOVs, or replacement with new, non-affected PBOVs, which would terminate the requirements of the existing AD. This AD is prompted by a decision by the FAA and a civil airworthiness authority to require modification or replacement of all affected PBOVs. We are issuing this AD to prevent loss of the yellow hydraulic system, which provides all the hydraulics for certain spoilers; elements of the hydraulics for flaps, stabilizer, pitch and yaw feel systems, pitch and yaw autopilot, and yaw damper; and elevator, rudder, and aileron.

Final rule.

2005-04-11 Airbus: Amendment 39-13983. Docket No. FAA-2004-19451; Directorate Identifier 2002-NM-138-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective April 5, 2005.

Affected ADs

(b) This AD supersedes AD 2002-08-14, amendment 39-12722 (67 FR 19655, April 23, 2002).

Applicability

(c) This AD applies to all Airbus Model A300 B2 and B4 series airplanes; A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600); and A310 series airplanes; certificated in any category.

Unsafe Condition

(d) This AD was prompted by a decision by the FAA and a civil airworthiness authority to require modification or replacement of all affected parking brake operated valves (PBOV).

The FAA proposed to amend part 39 of the Federal Aviation Regulations (14 CFR Part 39) with an AD to supersede AD 2002-08-14, amendment 39-12722 (67 FR 19655, April 23, 2002). The existing AD applies to all Airbus Model A300 B2 and B4; A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); and A310 series airplanes. The proposed AD was published in the Federal Register on October 27, 2004 (69 FR 62627), to retain certain requirements of the existing AD. The action also proposed to require modification of all affected parking brake operated valves (PBOVs), or replacement with new, non-affected PBOVs, which would terminate the requirements of the existing AD.

Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been submitted on the proposed AD.

Request To Withdraw the Proposed AD

One commenter, on behalf of its member operators, has no technical objection to the proposed AD, but requests withdrawing the proposed AD because the service information specified in Table 1 of the proposed AD meets the intent of the proposed AD.

We do not agree with the commenter's request to withdraw the proposed AD. There is no legal requirement for an operator to incorporate a service bulletin without an AD. Therefore, it is necessary to issue this AD to mandate that certain actions be done to correct the identified unsafe condition.

Conclusion

We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD as proposed, except as discussed under "Changes to Applicability."

Changes to Applicability

In the proposed AD, we inadvertently did not include Model A300 C4- 605R Variant F airplanes. We are including that airplane model in this AD. No airplanes of that model are currently on the U.S. Register and thus providing notice and opportunity for public comment is unnecessary before this AD is issued. We have determined that this change 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. This AD will affect about 168 airplanes of U.S. registry.

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