14 CFR Part 39

[Docket No. FAA-2004-18809; Directorate Identifier 2004-NM-91-AD; 
Amendment 39-13873; AD 2004-23-18]

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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Model A319, A320, and A321 series airplanes. This AD 
requires revising the airplane flight manual (AFM) to prohibit 
operators from performing CAT 2 or CAT 3 automatic landings or roll-
outs at certain airports. This AD also provides for an optional 
terminating action for the AFM revision. This AD is prompted by data 
showing that the magnetic variation table installed in the Honeywell 
inertial reference system (IRS) is obsolete at certain airports. We are 
issuing this AD to prevent the airplane from departing the runway 
during a CAT 2 or CAT 3 automatic landing or roll-out, due to magnetic 
and IRS deviations.

DATES: This AD becomes effective January 3, 2005.
    The incorporation by reference of a certain publication listed in 
the AD is approved by the Director of the Federal Register as of 
January 3, 2005.

Examining the Docket

    The AD docket contains the proposed AD, comments, and any final 
disposition. You can examine the AD docket on the Internet at <a href="http://dms.dot.gov">http://dms.dot.gov</a>, or in person at the Docket Management Facility office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT 
street address stated in the ADDRESSES section.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with

[[Page 68776]]

an AD for certain Airbus Model A319, A320, and A321 series airplanes. 
The proposed AD was published in the Federal Register on August 10, 
2004 (69 FR 48426), to require revising the airplane flight manual 
(AFM) to prohibit operators from performing CAT 2 or CAT 3 automatic 
landings or roll-outs at certain airports. The proposed AD also 
provided for an optional terminating action for the AFM revision.

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. The commenters support the proposed AD.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been submitted, and determined that air safety and 
the public interest require adopting the AD as proposed.

Costs of Compliance

    This AD will affect about 242 airplanes of U.S. registry. The AFM 
revision will take about 1 work hour per airplane, at an average labor 
rate of $65 per work hour. Based on these figures, the estimated cost 
of the required AFM revision for U.S. operators is $15,730, or $65 per 
airplane.

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'' 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.
    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.
