14 CFR Part 39

[Docket No. FAA-2004-19537; Directorate Identifier 2004-NM-145-AD;
Amendment 39-13993; AD 2005-05-05]
RIN 2120-AA64

Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and
F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes
(Collectively Called A300-600); and Model A310 Series Airplanes;
Equipped With Certain Honeywell Inertial Reference Units (IRU)

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and
Model C4-605R Variant F airplanes (collectively called A300-600); and
Model A310 series airplanes; equipped with certain Honeywell inertial
reference units (IRUs). This AD requires revising the Limitations
section of the airplane flight manual to prohibit the use of CAT 2 and
CAT 3 automatic landing and rollout procedures at certain airports.
This AD is prompted by a report that some magnetic deviation tables in
the IRU database are obsolete and contain significant differences with
the real magnetic deviations. We are issuing this AD to prevent an
airplane from deviating from the runway centerline, and possibly
departing the runway.

DATES: This AD becomes effective April 15, 2005.
The incorporation by reference of certain publications listed in
the AD is approved by the Director of the Federal Register as of April
15, 2005.

ADDRESSES: For service information identified in this AD, contact
Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France.
Docket: The AD docket contains the proposed AD, comments, and any
final disposition. You can examine the AD docket on the Internet at
http://dms.dot.gov, 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 U.S.
Department of Transportation, 400 Seventh Street, SW., room PL-401,
Washington, DC. This docket number is FAA-2004-19537; the directorate
identifier for this docket is 2004-NM-145-AD.

FOR FURTHER INFORMATION CONTACT: Tim Backman, Aerospace Engineer,
International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with an AD for all Airbus Model A300 B4-600, B4-600R, and F4-600R
series airplanes, and Model C4-605R Variant F airplanes (collectively
called A300-600); and Model A310 series airplanes; equipped with
certain Honeywell inertial reference units (IRUs). That action,
published in the Federal Register on November 5, 2004 (69 FR 64520),
proposed to require revising the Limitations section of the airplane
flight manual (AFM) to prohibit the use of CAT 2 and CAT 3 automatic
landing and rollout procedures at certain airports.

Comments

We provided the public the opportunity to participate in the
development of this AD. We have considered the comment that has been
submitted on the proposed AD. The commenter supports the proposed AD.

Explanation of Changes Made to This Final Rule

We have revised Table 2 of this AD to more clearly identify the
applicable airplane flight manuals (AFM) to be revised.
In Table 2 of the proposed AD we referenced an incorrect date for
the temporary revisions. We have revised Table 2 of this final rule to
correct that information.

Conclusion

We have carefully reviewed the available data, including the
comment that has been submitted, and determined that air safety and the
public interest require adopting the AD as proposed, with the changes
described previously. We have determined that these changes will
neither increase the economic burden on any operator nor increase the
scope of the AD.

Costs of Compliance

This AD will affect about 136 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,

[[Page 12118]]

the estimated cost of the AD for U.S. operators is $8,840, or $65 per
airplane.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

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.
