98055-4056.
Discussion
A proposal to amend part 39 of the Federal Aviation Regulations (14
CFR part 39) to add an airworthiness directive (AD) applicable to
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; was published as a
notice of proposed rulemaking (NPRM) in the Federal Register on
December 4, 2002 (67 FR 72115) (hereafter referred to as the ``original
NPRM''). That original NPRM would have required, among other actions,
replacement of certain pitot probes with certain new pitot probes. That
original NPRM was prompted by 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
[[Page 35187]]
indicated airspeed, if not corrected, could result in inadvertent
excursions outside the normal flight envelope.
Actions Since Issuance of Previous Proposal
Since the issuance of the original NPRM, the Direction
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), which is the
airworthiness authority for France, has issued a new revision to French
airworthiness directive 2001-265(B) R1, dated December 12, 2001, which
was one of the French airworthiness directives cited in the original
NPRM. This new revision, French airworthiness directive 2001-265(B) R2,
dated November 13, 2002, among other things, specifies enlarging the
holes for the pitot probes and clarifies the name of a parts
manufacturer.
New revisions to two of the service bulletins that were cited in
the original NPRM were issued to revise certain procedures to specify
the need to enlarge certain holes when replacing the pitot probes. The
various revisions to the two service bulletins are described as
follows:
[sbull] A310-34-2154, Revision 01, dated April 19, 2000, was cited
in the original NPRM as an appropriate source of service information.
The manufacturer later issued Revision 02, dated November 5, 2001;
Revision 03, dated January 25, 2002; Revision 04, dated April 30, 2002;
Revision 05, dated July 9, 2002; and Revision 06, dated August 6, 2002.
All of these revisions add airplanes in the effectivity of the service
bulletin. However, Revision 04 of the service bulletin also includes
procedures for enlarging the holes for installing the pitot probes.
Revision 07, dated October 8, 2002, which is cited in this supplemental
NPRM as the appropriate source of information for Model A310 series
airplanes, also adds airplanes to the effectivity of the service
bulletin.
[sbull] A300-34-6141, dated December 3, 2001, was cited in the
original NPRM as an appropriate source of service information. The
manufacturer later issued Revision 01, dated February 20, 2002, to add
airplanes to the effectivity of the service bulletin. Revision 02,
dated April 30, 2002, was issued to provide procedures for enlarging
the holes for installing the pitot probes. Revision 03, dated August
27, 2002, which is cited in this supplemental NPRM as the appropriate
source of information for Model A300 B4-600R series airplanes, was
issued to add airplanes to the effectivity of the service bulletin.
Comments
Due consideration has been given to the comments received in
response to the NPRM.
Support for the Proposed NPRM
One commenter, the manufacturer, supports the content of the
proposed NPRM.
Request to Correct Name of Parts Supplier
One commenter suggests changing all references throughout the
original NPRM from BF Goodrich to Rosemount Aerospace Inc. The
commenter states that Rosemount Aerospace is the correct legal name.
The FAA concurs with this request and has revised this supplemental
NPRM accordingly.
Request To Delay Issuance of Proposal
One commenter states that it has no concerns with the actions
required by the original NPRM, and that those actions have been
accomplished on all Model A319 and A320 series airplanes. However,
since this accomplishment, the commenter has experienced a continuation
in airspeed anomalies. For this reason, the commenter states that it
will share such data with us, and suggests that we conduct a more
extensive review of the experience of additional operators regarding
airspeed anomalies before mandating any actions in an AD.
Although we acknowledge the commenter's concern, we do not concur
that issuance of this proposed AD should be delayed until we receive
additional data regarding airspeed anomalies. However, based on these
concerns, we encourage that additional data be submitted to us by the
commenter or others. We have determined that to delay this action would
be inappropriate since an unsafe condition exists, and that the revised
procedure for replacing the pitot probes must be accomplished to ensure
continued safety. Additional rulemaking may be considered in the
future, if warranted by additional data regarding the identified unsafe
condition. No change to this supplemental NPRM is necessary in this
regard.
Request To Expand the Applicability of the Proposed NPRM
One commenter is concerned about certain requirements in the
original NPRM regarding the pitot probes used on certain airplane
models. The commenter asks whether the unsafe condition identified on
one manufacturer's product line of pitot probes also exists on the
product lines of other manufacturers. The commenter states that one of
the manufacturers issued an alert service bulletin regarding
unauthorized repairs on certain pitot static tubes found installed on a
number of airplane models. The commenter is concerned that additional
airplane models also may have similar discrepant pitot probes
installed. In addition, if a serious safety issue exists for pitot
probes manufactured per the requirements of Technical Standard Order
TSO C-16, dated September 1, 1948, and amended April 16, 1951, the
applicability of the original NPRM may need to be expanded.
We acknowledge the commenter's concern and may consider additional
rulemaking to address that concern in the future on certain airplanes.
While there may be merit to the commenter's suggestions, this
supplemental NPRM is not the appropriate context in which to evaluate
those suggestions. Since the suggested changes would alter the actions
currently required by this supplemental NPRM, additional rulemaking
would be required. We find that to delay this action would be
inappropriate in light of the identified unsafe condition. We do not
concur that we should expand the applicability of this supplemental
NPRM. No change to the applicability of this supplemental NPRM is
necessary in this regard.
Request to Add a Service Bulletin Reference
One commenter states that a reference to Airbus Service Bulletin
A320-34-1170, Revision 05, dated September 11, 2000, should be added to
certain paragraphs in the original NPRM, for certain airplanes. That
service bulletin describes procedures for replacing certain Thales
(formerly Sextant) pitot probes with new Rosemount Aerospace pitot
probes.
We do not concur for several reasons. First, the commenter did not
specify any justification for adding a reference to Airbus Service
Bulletin A320-34-1170. Second, French airworthiness directive 2001-
265(B) R2 does not include a reference to that service bulletin. In
addition, French airworthiness directive 2001-362(B), dated August 8,
2001, states that airplanes equipped with certain pitot probes per
Airbus Service Bulletin A320-34-1170 are not applicable to the
requirements of that airworthiness directive. No change to this
supplemental NPRM is necessary in this regard.
Conclusion
Since these changes expand the scope of the original NPRM, we have
determined that it is necessary to reopen the comment period to provide
[[Page 35188]]
additional opportunity for public comment.
Cost Impact
We estimate that 559 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 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 proposed AD. The average
labor rate is $60 per work hour. ``Table--Cost Figures'' is as follows:

----------------------------------------------------------------------------------------------------------------
The cost impact figures in the table 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 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.
