Airworthiness Directives; Airbus Model A330-200 and -300 Series
Airplanes, Model A340-200 and -300 Series Airplanes, and Model A340-541
and -642 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Model A330-200 and -300 series airplanes, Model A340-200
and -300 series airplanes, and Model A340-541 and -642 airplanes. This
AD requires replacing certain Thales Avionics pitot probes with certain
other pitot probes. This AD results from reports of airspeed indication
discrepancies while flying at high altitudes in inclement weather
conditions. We are issuing this AD to prevent airspeed discrepancies,
which could lead to disconnection of the autopilot and/or auto-thrust
functions, and reversion to flight control alternate law and consequent
increased pilot workload. Depending on the prevailing airplane altitude
and weather, this condition, if not corrected, could result in reduced
control of the airplane.
DATES: This AD becomes effective September 8, 2009.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of September 8,
2009.
We must receive comments on this AD by October 5, 2009.

SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued a
Notification of a Proposal to Issue an Airworthiness Directive (PAD),
PAD 09-099, dated August 10, 2009 (referred to after this as ``the EASA
PAD''), to correct an unsafe condition for certain Airbus Model A330-
200 and -300 series airplanes, Model A340-200 and -300 series
airplanes, and Model A340-541 and -642 airplanes. The EASA PAD states
that airspeed indication discrepancies have been reported on Model A330
and A340 airplanes while flying at high altitudes in inclement weather
conditions. Investigation results indicate that these airplanes
equipped with certain Thales Avionics pitot probes appear to have a
greater susceptibility to adverse environmental conditions than certain
other pitot probes.
The EASA PAD also states that a new Thales Avionics pitot probe
having part number (P/N) C16195BA has been designed, which improves the
airspeed indication behavior in heavy rain conditions on Model A320
airplanes. This same pitot probe standard has been made available as an
optional installation on Model A330 and A340 airplanes, and although
this has shown to be an improvement over the previous Thales Avionics
pitot probe, P/N C16195AA standard, it has not yet demonstrated the
same level of robustness to withstand high-altitude ice crystals as
Goodrich pitot probes having P/N 0851HL.
We are issuing this AD to prevent airspeed discrepancies, which
could lead to disconnection of the autopilot and/or auto-thrust
functions, and reversion to flight control alternate law and consequent
increased pilot workload. Depending on the prevailing airplane altitude
and weather, this condition, if not corrected, could result in reduced
control of the airplane.
Other Relevant Rulemaking
On February 4, 2004, we issued AD 2004-03-33, Amendment 39-13477
(69 FR 9936, March 3, 2004), for 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
[[Page 45551]]
airplanes; Model A330-301, -321, -322, -341, and -342 airplanes; and
Model A340 series airplanes. Paragraphs (g)(1) and (h)(1) of that AD
require, for some Model A330 and A340 airplanes, replacement of certain
pitot probes with Goodrich pitot probes having P/N 0851HL. For other
Model A330 and A340 airplanes, paragraphs (g)(2) and (h)(2) of that AD
require replacement of certain pitot probes with Thales Avionics pitot
probe having P/N C16195AA.

Airbus Service Bulletins A330-34-3206, A340-34-4200, and A340-34-
5068 describe procedures for replacing Thales Avionics pitot probes, P/
N C16195AA, in positions 1, 2, and 3 (captain, first officer, and
standby, respectively) with Thales Avionics pitot probes, P/N C16195BA
in those positions.
Airbus Mandatory Service Bulletins A330-34-3231, A340-34-4238, and

probes, P/N C16195BA, in positions 1 and 3 (captain and standby,
respectively) with a Goodrich pitot probe, P/N 0851HL, in those
positions.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the service
information referenced above. We are issuing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
We have reviewed the EASA PAD, which proposes to require replacing
certain Thales Avionics pitot probes installed on certain Airbus Model
A330 and A340 airplanes. Additionally, we have reviewed the numerous
airspeed anomalies recently reported on Model A330 and A340 airplanes.
Based on our review, we have determined that an unsafe condition exists
and immediate airworthiness action for the Model A330 and A340 fleet is
warranted.
Therefore, we are issuing this AD to prevent airspeed
discrepancies, which could lead to disconnection of the autopilot and/
or auto-thrust functions, and reversion to flight control alternate law
and consequent increased pilot workload. Depending on the prevailing
airplane altitude and weather, this condition, if not corrected, could
result in reduced control of the airplane. This AD requires replacing
Thales Avionics pitot probes having P/N C16195AA and P/N C16195BA at
positions 1 (captain) and 3 (standby) with Goodrich pitot probes having
P/N 0851HL at positions 1 and 3. This AD also requires replacing Thales
Avionics pitot probes having P/N C16195AA at position 2 (first officer)
with Thales Avionics pitot probes having P/N C16195BA at position 2. In
addition, this AD provides for optional installation of Goodrich pitot
probes having P/N 0851HL at position 2.
We have determined that doing the actions in this new AD terminates
the requirements of paragraphs (g)(2) and (h)(2) of AD 2004-03-33, and
also is acceptable for compliance with paragraphs (g)(1) and (h)(1) of
AD 2004-03-33. We might consider further rulemaking to revise AD 2004-
03-33.
This AD corresponds to the EASA PAD, which addresses the identified
unsafe condition on Model A330 and A340 airplanes. AD 2004-03-33 is
applicable to Model A330 and A340 airplanes and other Airbus airplane
models. We might consider further rulemaking to address other Airbus
models.
FAA's Justification and Determination of the Effective Date
Airspeed discrepancies could lead to disconnection of the autopilot
and/or auto-thrust functions, and reversion to flight control alternate
law and consequent increased pilot workload. Depending on the
prevailing airplane altitude and weather, this condition, if not
corrected, could result in reduced control of the airplane. Because of
our requirement to promote safe flight of civil aircraft and thus, the
critical need to assure the proper functioning of the pitot probes, and
the short compliance time involved with this action, this AD must be
issued immediately.
The required compliance time of 120 days is usually sufficient to
allow for a brief comment period before adoption of a final rule. In
this AD, however, the compliance time of 120 days was selected because
of a short-term problem with the availability of sufficient replacement
parts; a shorter compliance time might have resulted in the unnecessary
removal of airplanes from service pending delivery of replacement
parts. Nevertheless, we have determined that immediate adoption of this
AD is necessary in this case because of the importance of initiating
the required replacements as soon as possible.
Because an unsafe condition exists that requires the immediate
adoption of this AD, we find that notice and opportunity for prior
public comment hereon are impracticable and that good cause exists for
making this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
``Docket No. FAA-2009-0781; Directorate Identifier 2009-NM-111-AD'' at
the beginning of your comments. We specifically invite comments on the
overall regulatory, economic, environmental, and energy aspects of this
AD. We will consider all comments received by the closing date and may
amend this AD because of those comments.
[[Page 45552]]
We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
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 the 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. 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 and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
