14 CFR Part 39

[Docket No. 2002-NM-137-AD; Amendment 39-13389; AD 2003-25-06]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A300 B4-622R and A300 F4-
622R Airplanes, and Model A310-324 and -325 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Airbus Model A300 B4-622R and A300 F4-622R 
airplanes, and Model A310-324 and -325 series airplanes, that are 
equipped with Pratt & Whitney PW4000 series engines. This AD requires 
replacement of the existing flexible hose assembly that connects the 
oil pressure transmitter to the main oil circuit, with a new improved 
tube assembly. This action is necessary to prevent failure of the oil 
pressure indicator and low-oil-pressure warning in the event of an 
engine fire, which could result in an unannounced shutdown of the 
engine. This action is intended to address the identified unsafe 
condition.

DATES: Effective January 22, 2004.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of January 22, 2004.

ADDRESSES: 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.

International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to certain Airbus Model A300 B4-622R 
and A300 F4-622R airplanes, and Model A310-324 and -325 series 
airplanes, that are equipped with Pratt & Whitney PW4000 series 
engines, was published in the Federal Register on September 19, 2003 
(68 FR 54872). That action proposed to require replacement of the 
existing flexible hose assembly that connects the oil pressure 
transmitter to the main oil circuit, with a new improved tube assembly.

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. The commenter has no objection to the 
proposed AD.

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 as proposed.

Cost Impact

    The FAA estimates that 139 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 10 work hours per 
airplane to accomplish the required actions, and that the average labor 
rate is $65 per work hour. Required parts will be provided by the 
manufacturer at no charge. Based on these figures, the cost impact of 
this AD on U.S. operators is estimated to be $90,350, or $650 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 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.
