ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
Several reports have recently been received of loose pneumatic
quick-disconnect unions on Goodrich pitot probes P/N (part number)
0851HL. These may be the result of mis-torque of the affected unions
at equipment manufacturing level. Investigations are still on-going
to determine the root cause(s).
This condition, if not corrected, could lead to an air leak,
resulting in incorrect total pressure measurement and consequent
erroneous Calibrated Airspeed (CAS)/MACH parameters delivered by the
Air Data Computer (ADC).
* * * * *
Loss or fluctuation of indicated airspeed could result in misleading
information provided to the flightcrew. We are issuing this AD to
require actions to correct the unsafe condition on these products.
DATES: This AD becomes effective September 22, 2010.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of September 22,
2010.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on January 21, 2010 (75
FR 3420). That NPRM proposed to correct an unsafe condition for the
specified products.
Since that NPRM was issued, the European Aviation Safety Agency
(EASA), which is the aviation authority for the Member States of the
European Community, has issued EASA Airworthiness Directive 2009-
0202R1, dated April 15, 2010 (referred to after this as ``the MCAI''),
to correct an unsafe condition for the specified products. (MCAI 2009-
0202-E, dated September 21, 2009, and corrected September 22, 2009, was
referred to in the NPRM.) The
[[Page 50872]]
MCAI has been revised to exclude pitot probes marked with a red torque
check-indicating mark. If the red indicating mark is on the pitot
probe, it can be installed with no further action. The MCAI states:
Several reports have recently been received of loose pneumatic
quick-disconnect unions on Goodrich pitot probes P/N (part number)
0851HL. These may be the result of mis-torque of the affected unions
at equipment manufacturing level. Investigations are still on-going
to determine the root cause(s).
This condition, if not corrected, could lead to an air leak,
resulting in incorrect total pressure measurement and consequent
erroneous Calibrated Airspeed (CAS)/MACH parameters delivered by the
Air Data Computer (ADC).
As a precautionary measure, this AD requires a torque check of
the pneumatic quick-disconnect union on certain Goodrich P/N 0851HL
pitot probes and corrective action, depending on findings.
* * * * *
This AD [MCAI] is revised in order to exclude from the torque-
check required by paragraph (4) of this AD those pitot probes marked
with a red torque check-mark.
Loss or fluctuation of indicated airspeed could result in misleading
information provided to the flightcrew. If the quick-disconnect union
fitted on the pitot probe is not adequately torqued, the corrective
action includes applying torque. You may obtain further information by
examining the MCAI in the AD docket.
Revised Service Information
Airbus has issued All Operators Telexes (AOTs) A330-34A3235 (for
Model A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -
323, -341, -342, and -343 airplanes); A340-34A4241 (for Model A340-211,
-212, -213, -311, -312, and -313 airplanes); and A340-34A5074 (for
Model A340-541 and -642 airplanes); all Revision 02, all dated March 1,
2010. We have revised Table 1 of this AD to add Revision 02 of the AOTs
as the appropriate source of service information for accomplishing the
specified actions. We have also added a new Table 2 to this AD to give
credit for accomplishing the actions using the previous issues of the
AOTs.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received.
Support for NPRM
The Airline Pilots Association (ALPA) supports the intent of the
NPRM and appreciates the opportunity to comment.
Request for Credit for Actions Accomplished Previously
Delta Airlines asks that the NPRM be revised to allow credit for
either adequate torqueing of the pneumatic quick-disconnect union of
each pitot probe for affected pitot probes, or updating the aircraft
maintenance manual (AMM) to ensure that the pneumatic quick-disconnect
union of each pitot probe is torqued properly during installation.
Delta states that Airbus AOT A330-34A3235, Revision 02, dated March 1,
2010, specifies that for pitot probes that are still held as spares
there are two choices of actions as noted above.
Delta also asks that the NPRM be revised to give credit for pitot
probes remanufactured and returned to Delta by Goodrich on which the
proposed requirements were done before Airbus AOT A330-32A3235 dated
September 10, 2009, or Revision 1, dated September 21, 2009, were
issued. Delta notes that those pitot probes were returned with adequate
torque but do not have a torque check indicating mark (Airbus AOT A330-
32A3235, Revision 02, dated March 1, 2010, adds a torque check
indicating mark after the pitot probe is adequately torqued). Delta
states that it was proactive in correcting any deficiencies by taking
immediate corrective actions. Delta adds that an allowance for this
method of compliance should be included in the NPRM to avoid processing
an alternative method of compliance (AMOC).
We disagree with the commenter's request to give credit for pitot
probes remanufactured by Goodrich because non-marked pitot probes may
be unintentionally installed on the airplane without performing a
proper torque check. However, under the provisions of paragraph (h) of
the final rule, we will consider requests for approval of an
alternative method of compliance for using specific pitot probes
identified by an operator if sufficient data are submitted to
substantiate that the pitot probes would provide an acceptable level of
safety.
Regarding Delta's comment on spare parts, we have revised paragraph
(g)(4) of this AD to give credit for installing parts that have the
torque check indicating mark.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously. We determined that these
changes will not increase the economic burden on any operator or
increase the scope of the AD.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Explanation of Change to Costs of Compliance
Since issuance of the NPRM, we have increased the labor rate used
in the Costs of Compliance from $80 per work-hour to $85 per work-hour.
The Costs of Compliance information, below, reflects this increase in
the specified hourly labor rate.
Costs of Compliance
We estimate that this AD will affect 47 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
the AD on U.S. operators to be $3,995, or $85 per product.
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.
[[Page 50873]]
Regulatory Findings
We 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 this AD:
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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

2. The FAA amends Sec. 39.13 by adding the following new AD:
2010-17-02 Airbus: Amendment 39-16392. Docket No. FAA-2010-0041;
Directorate Identifier 2009-NM-218-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective
September 22, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the Airbus airplanes identified in
paragraphs (c)(1), (c)(2), and (c)(3) of this AD; certificated in
any category; all manufacturer serial numbers; with pitot probes
having Goodrich part number (P/N) 0851HL, serial numbers 267328
through 270714 inclusive.
(1) Model A330-201, -202, -203, -223, -243, -301, -302, -303, -
321, -322, -323, -341, -342, and -343 airplanes.
(2) Model A340-211, -212, -213, -311, -312, and -313 airplanes.
(3) Model A340-541 and -642 airplanes.
Subject
(d) Air Transport Association (ATA) of America Code 34:
Navigation.
Reason
(e) The mandatory continued airworthiness information (MCAI)
states:
Several reports have recently been received of loose pneumatic
quick-disconnect unions on Goodrich pitot probes P/N (part number)
0851HL. These may be the result of mis-torque of the affected unions
at equipment manufacturing level. Investigations are still on-going
to determine the root cause(s).
This condition, if not corrected, could lead to an air leak,
resulting in incorrect total pressure measurement and consequent
erroneous Calibrated Airspeed (CAS)/MACH parameters delivered by the
Air Data Computer (ADC).
As a precautionary measure, this AD requires a torque check of
the pneumatic quick-disconnect union on certain Goodrich P/N 0851HL
pitot probes and corrective action, depending on findings.
* * * * *
This AD [MCAI] is revised in order to exclude from the torque-
check required by paragraph (4) of this AD those pitot probes marked
with a red torque check-mark.
Loss or fluctuation of indicated airspeed could result in misleading
information provided to the flightcrew. If the quick-disconnect
union fitted on the pitot probe is not adequately torqued, the
corrective action includes applying torque.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) At the time specified, do the following actions.
(1) Within 14 days after the effective date of this AD: Perform
a torque check of the pneumatic quick-disconnect union of each pitot
probe having Goodrich P/N 0851HL, serial numbers 267328 through
270714 inclusive, to determine if the torque is adequate, in
accordance with the instructions of the applicable service
information specified in Table 1 of this AD. Before further flight,
do all applicable corrective actions in accordance with the
instructions of the applicable service information specified in
Table 1 of this AD.

required by paragraph (g)(1) of this AD have been done; or an intact
red torque check mark is visible on the interface of the pnuematic
quick disconnect union and the union mount.
FAA AD Differences
Note 1: This AD differs from the MCAI and/or service information
as follows:
Where the MCAI includes a compliance time of ``5 days,'' we have
determined that a compliance time of ``within 14 days after the
effective date of the AD'' is appropriate. The manufacturer and EASA
agree with this expansion in compliance time.
Other FAA AD Provisions
(h) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, FAA, Transport Airplane Directorate,
has the authority to approve AMOCs for this AD, if requested using
the procedures found in 14 CFR 39.19. Send information to ATTN:
Vladimir Ulyanov, Aerospace Engineer, International Branch, ANM-116,
FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton,
Washington 98057-3356; telephone (425) 227-1138; fax (425) 227-1149.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your principal maintenance inspector (PMI) or
principal avionics inspector (PAI), as appropriate, or lacking a
principal inspector, your local Flight Standards District Office.
The AMOC approval letter must specifically reference this AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
