Discussion
The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC),
which is the airworthiness authority for France, notified the FAA that
an unsafe condition may exist on certain Airbus Model A300 B2 and B4
series airplanes; Model A300 B4-600, A300 B4-600R, and A300 F4-600R
series airplanes (collectively called A300-600); Model A310 series
airplanes; Model A319, A320, and A321 series airplanes; Model A330-301,
-321, -322, -341, and -342 series airplanes; and Model A340 series
airplanes. The DGAC advises that operators have reported several cases
of loss or fluctuation of indicated airspeed when flying through heavy
precipitation or freezing weather conditions. The probable cause has
been attributed to the presence of ice crystals and/or water exceeding
the weather limits for which the pitot probes are currently certified.
Loss or fluctuation of indicated airspeed, if not corrected, could
result in inadvertent excursions outside the normal flight envelope.
Explanation of Relevant Service Information
Airbus has issued Service Bulletin A300-34-0166, dated March 30,
2001 (for Model A300 B2 and B4 series airplanes); Service Bulletin
A300-34-6116, Revision 02, dated May 25, 2000 (for Model A300 B4-600,

A310-34-2137, Revision 02, dated May 25, 2000 (for Model A310 series
airplanes). These service bulletins describe procedures for replacement
of the Sextant pitot probes from the forward fuselage panel between FR6
and FR7 with new BF Goodrich pitot probes (including O-rings, gaskets,
and nuts). In lieu of this replacement, Airbus has issued Service
Bulletin A300-34-6141, dated December 3, 2001 (for Model A300 B4-600R
series airplanes); and Airbus Service Bulletin A310-34-2154, Revision
01, dated April 19, 2000 (for Model A310 series airplanes). These
service bulletins describe procedures for replacement of the Sextant
pitot probes from the forward fuselage panel between FR6 and FR7 with
new, improved Sextant pitot probes (including O-rings, gaskets, and
nuts).
[[Page 72116]]
Airbus also has issued Service Bulletin A300-34-069, Revision 05,
dated April 8, 1982, as revised by A300 Service Bulletin Change Notice
5A, dated February 16, 1987 (for Model A300 B2 and A300 B4 series
airplanes), which describes procedures for replacement of the
Captain's, First Officer's, and standby Badin Crouzet pitot probes in
zones 121 and 122 between STA881/FR6 and STA904FR7 with new Badin
Crouzet pitot probes. The replacement includes replacing the O-rings,
gaskets, and nuts; and modifying the electrical wiring and the
equipment of the electrical wiring.
Airbus also has issued Service Bulletin A300-21-053, Revision 2,
dated January 3, 1980 (for Model A300 B2 and A300 B4 series airplanes),
which describes procedures for modifying the relay box of the automatic
ground depressurization system. The modification includes installing
blanking plates, a relay assembly, and placards; incorporating and
attaching to existing bundles a new bundle with cable ties; and
plugging unused holes of a certain relay.
Airbus also has issued Service Bulletin A300-32-052, dated November
15, 1976 (for Model A300 B2 and B4 series aiplanes), which describes
procedures for cleaning, restoring paint coats, and applying Mystik
tape 7355 to shock strut (barrel) of the main landing gear; and
replacing the lower arm link with a new, reidentified lower arm lock
link.
Airbus also has issued Service Bulletin A300-22-031, dated June 25,
1979 (for Model A300 B2 and A300 B4 series airplanes), which describes
procedures for modification of the electronic racks, electrical wiring,
and cable routing. The modification includes drilling and deburring
structure, and plugging unused holes in connectors.
Airbus also has issued Service Bulletin A320-34-1127, dated April
24, 1997 (for Model A319, A320, and A321 series airplanes), which
describes procedures for replacement of Thales (previously Sextant)
pitot probes in zones 125, 9DA2, and 122 with new Thales pitot probes.
Airbus also has issued Service Bulletin A330-34-3038, dated
November 19, 1996 (for Model A330-301, -321, -322, -341, and -342
series airplanes), which describes procedures for replacement of the
Rosemount pitot probes in zones 121 and 122 with new BF Goodrich pitot
probes. In lieu of this replacement for certain airplanes, Airbus also
has issued Service Bulletin A330-34-3071, dated December 11, 1998 (for
Model A330-301 series airplanes), which describes procedures for
replacement of the Rosemount pitot probes in zones 121 and 122 with new
Sextant pitot probes.
In addition, Airbus has issued Service Bulletin A340-34-4042, dated
November 19, 1996 (for Model A340-211, -212, -213, -311, -312, and -313
series airplanes), which describes procedures for replacement of the
Rosemount pitot probes in zones 121 and 122 with new BF Goodrich pitot
probes. In lieu of this replacement for certain airplanes, Airbus also
has issued Service Bulletin A340-34-4079, dated December 11, 1998 (for
Model A340-211, -212, and -311 series airplanes), which describes
procedures for replacement of the Rosemount pitot probes in zones 121
and 122 with new Sextant pitot probes.
Accomplishment of the actions specified in the service bulletins is
intended to adequately address the identified unsafe condition. The
DGAC classified these service bulletins as mandatory and issued French
airworthiness directives 2001-353(B), dated August 8, 2001; 2001-
354(B), dated August 8, 2001; 2001-362(B), dated August 8, 2001; and
2001-265(B) R1, dated December 12, 2001; in order to assure the
continued airworthiness of these airplanes in France.
FAA's Conclusions
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. Pursuant to this
bilateral airworthiness agreement, the DGAC has kept the FAA informed
of the situation described above. The FAA has examined the findings of
the DGAC, reviewed all available information, and determined that AD
action is necessary for products of this type design that are
certificated for operation in the United States.
Explanation of Requirements of Proposed Rule
Since an unsafe condition has been identified that is likely to
exist or develop on other airplanes of the same type design registered
in the United States, the proposed AD would require accomplishment of
the actions specified in the applicable service bulletins described
previously.
Cost Impact
The FAA estimates that 559 airplanes of U.S. registry would be
affected by this proposed AD. The ``Table--Cost Figures'' shows the
estimated cost impact for certain airplanes affected by this AD. The
average labor rate is $60 per work hour. ``Table--Cost Figures'' is as
follows:

[[Page 72117]]
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. 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.
Currently, there are no Airbus Model A340-211, -212, -213, -311, -
312, and -313 series airplanes on the U.S. Register. However, should an
affected airplane be imported and placed on the U.S. Register in the
future, it would require approximately 3 work hours to accomplish the
required actions, at an average labor rate of $60 per work hour. The
cost of required parts would be $6,000 or $11,100 (depending on
airplane configuration). Based on these figures, the cost impact of
this AD would be $6,180 or $11,280 per airplane (depending on airplane
configuration).
Regulatory Impact
The regulations proposed herein 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. Therefore, it
is determined that this proposal would not have federalism implications
under Executive Order 13132.
For the reasons discussed above, I certify that this 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) if promulgated, 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 copy of the draft
regulatory evaluation prepared for this action is contained in the
Rules Docket. A copy of it may be obtained by contacting the Rules
Docket at the location provided under the caption ADDRESSES.
