14 CFR Part 39

[Docket No. FAA-2004-19451; Directorate Identifier 2002-NM-138-AD]
RIN 2120-AA64

 
Airworthiness Directives; Airbus Model A300 B2 and B4; A300 B4-
600, B4-600R, and F4-600R (Collectively Called A300-600); and A310 
Series Airplanes

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.

SUPPLEMENTARY INFORMATION:

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.

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

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.
