Airworthiness Directives; Airbus Model A319, A320, A321, A330, 
and A340 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Airbus Model A319, A320, A321, A330, and A340 
series airplanes, that requires revising the Airplane Flight Manual to 
provide the flight crew with certain instructions associated with the 
Global Positioning System (GPS). This amendment also requires 
modification of the Global Positioning System Signal Unit (GPSSU) of 
the satellite navigational system. This amendment is prompted by 
issuance of mandatory continuing airworthiness information by a foreign 
civil airworthiness authority. The actions specified by this AD are 
intended to prevent position and altitude errors due to bad oscillator 
warm-up characteristics of the GPSSU, which could result in 
navigational errors that may exceed 0.5 nautical mile.

DATES: Effective April 27, 2000.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of April 27, 2000.

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.

FOR FURTHER INFORMATION CONTACT: Norman B. Martenson, Manager, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2110; fax (425) 227-1149.

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 A319, A320, 
A321, A330, and A340 series airplanes was published in the Federal 
Register on January 10, 2000 (65 FR 1350). That action proposed to 
require revising the Airplane Flight Manual to provide the flight crew 
with certain instructions associated with the Global Positioning System 
(GPS). That action also proposed to require modification of the Global 
Positioning System Signal Unit (GPSSU) of the satellite navigational 
system.

Comments

    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.

[[Page 15535]]

Explanation of Change Made

    Paragraphs (b)(3) and (b)(3)(i) of this AD have been changed to 
correct typographical errors that resulted in references to an 
incorrect service bulletin number. Paragraph (b)(3) of the proposed 
rule references ``Airbus Service Bulletin A30-34-4089, Revision 01, 
dated September 28, 1999'' as the appropriate source of service 
information for accomplishment of the modification required by 
paragraph (b) of the AD. Paragraph (b)(3)(i) of the proposed rule 
incorrectly references ``Airbus Service Bulletin A330-34-4089, Revision 
01, dated September 28, 1999.'' This AD references the appropriate 
service bulletin as ``Airbus Service Bulletin A340-34-4089, Revision 
01, dated September 28, 1999, for accomplishment of the modification 
required by paragraph (b) of this AD.

Conclusion

    After careful review of the available data, the FAA has determined 
that air safety and the public interest require the adoption of the 
rule with the change described previously. The FAA has determined that 
this change will neither increase the economic burden on any operator 
nor increase the scope of the AD.

Cost Impact

    The FAA estimates that 1 airplane of U.S. registry will be affected 
by this AD.
    It will take approximately 1 work hour per airplane to accomplish 
the required Airplane Flight Manual (AFM) revision, at an average labor 
rate of $60 per work hour. Based on these figures, the cost impact of 
the AFM revision required by this AD on U.S. operators is estimated to 
be $60, or $60 per airplane.
    It will take approximately 1 work hour per airplane to accomplish 
the required modification, at an average labor rate of $60 per work 
hour. Based on these figures, the cost impact of the modification 
required by this AD on U.S. operators is estimated to be $60, or $60 
per airplane.
    It will take between 3 to 14 work hours per airplane to accomplish 
the additional modifications required to be accomplished prior to or 
concurrent with the required modification, at an average labor rate of 
$60 per work. Required parts will be provided by the vendor or 
manufacturer at no cost to the operators. Based on these figures, the 
cost impact of the additional modifications required by this AD on U.S. 
operators is estimated to be between $180 to $840 per airplane.
    The cost impact figures discussed above are based on assumptions 
that no operator has yet accomplished any of the proposed requirements 
of this AD action, and that no operator would accomplish those actions 
in the future if this AD were not adopted.

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.
