Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to supersede an existing airworthiness directive (AD) that 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 existing 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. The existing AD also provides for optional terminating action for the requirements of that AD. This proposed AD would require modification of all affected PBOVs, or replacement with new, nonaffected PBOVs, which would terminate the requirements of the existing AD. This proposed 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 proposing 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.

DATES:

We must receive comments on this proposed AD by November 26, 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 Docket Number”) as a cross-reference for searching purposes.

Comments Invited

We invite you to submit any relevant written data, views, or arguments regarding this proposed AD. Send your comments to an address listed under ADDRESSES. Include “Docket No. FAA-2004-19451; Directorate Identifier 2002-NM-138-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed AD. We will consider all comments received by the closing date and may amend the proposed 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 personnel concerning this proposed 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.

Discussion

On April 12, 2002, we issued AD 2002-08-14, amendment 39-12722 (67 FR 19655, April 23, 2002), for all Airbus Model A300 B2 and B4; A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); and A310 series airplanes. That AD 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. That AD was prompted by issuance of mandatory continuing airworthiness information by the Direction Generale de l'Aviation Civile (DGAC), which is the airworthiness authority for France. We issued that 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.

Actions Since Existing AD Was Issued

The preamble to AD 2002-08-14 indicated that the FAA and the DGAC were considering a requirement to replace all affected PBOVs. We and the DGAC have determined that modification or replacement of all affected PBOVs should be required, and this proposed AD follows from that determination. The parallel French airworthiness directive is 2001-510(B) R1, dated May 15, 2002.

FAA's Determination and Requirements of the Proposed AD

These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. According to this bilateral airworthiness agreement, the DGAC has kept us informed of the situation described above. We have examined the DGAC's findings, evaluated all pertinent information, and determined that AD action is necessary for airplanes of this type design that are certificated for operation in the United States.

This proposed AD would supersede AD 2002-08-14. This proposed AD would retain certain requirements of the existing AD. This proposed AD would also require modification of all affected PBOVs, or replacement with new, nonaffected PBOVs, which would terminate the requirements of the existing AD. Accomplishment of the modification or replacement would be required in accordance with the service bulletins referenced in AD 2002-08-14 (Airbus Service Bulletins A300-32A0441, A300-32A6087, or A310-32A2124; all dated September 10, 2001; as applicable).

Change to Existing AD

This proposed AD would retain certain requirements of AD 2002-08-14. Since AD 2002-08-14 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table:

Revised Paragraph Identifiers

paragraph (a)paragraph (f).
paragraph (b)paragraph (g).
paragraph (d)paragraph (h).

Costs of Compliance

The following table provides the estimated costs for U.S. operators to comply with this proposed AD. This proposed AD would affect about 168 airplanes of U.S. registry.

Inspection of PBOV part number/serial number (required by AD 2002-08-14)265None$130
Modification/replacement (new proposed action)465No Charge260

Regulatory Findings

We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed 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 proposed AD. See the ADDRESSES section for a location to examine the regulatory evaluation.
