ACTION: Final rule; request for
comments.
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:
SUMMARY:
The heating capability of several Angle Of
Attack (AOA) transducer heating elements
removed from in-service aircraft have been
found to be below the minimum requirement.
Also, it was discovered that a large number
of AOA transducers repaired in an approved
maintenance facility were not calibrated
accurately.
Inaccurate calibration of the AOA
transducer and/or degraded AOA transducer
heating elements can result in early or late
activation of the stall warning, stick shaker
and stick pusher by the Stall Protection
Computer (SPC).

The unsafe condition is reduced
controllability of the airplane. This AD
requires actions that are intended to
address the unsafe condition described
in the MCAI.

SUPPLEMENTARY INFORMATION:
Discussion
The Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2008–35,
dated December 22, 2008 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:

removed from in-service aircraft have been
found to be below the minimum requirement.
Also, it was discovered that a large number
of AOA transducers repaired in an approved
maintenance facility were not calibrated
accurately.
Inaccurate calibration of the AOA
transducer and/or degraded AOA transducer
heating elements can result in early or late
activation of the stall warning, stick shaker
and stick pusher by the Stall Protection
Computer (SPC).
This [Canadian] directive mandates a
periodic inspection of the inrush current to
verify the AOA heating capability and
replacement of the inaccurately calibrated
AOA transducers.
The unsafe condition is reduced
controllability of the airplane. You may
obtain further information by examining
the MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Service
Bulletin 601R–27–153, Revision A,
dated December 16, 2008. The actions
described in this service information are
intended to correct the unsafe condition
identified in the MCAI.
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
MCAI and service information
referenced above. We are issuing this
AD because we evaluated all pertinent
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between the 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
E:\FR\FM\20FER1.SGM
20FER1
7790
Federal Register / Vol. 74, No. 33 / Friday, February 20, 2009 / Rules and Regulations
MCAI in order to follow FAA policies.
Any such differences are highlighted in
a NOTE within the AD.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The FAA has found that the risk to
the flying public justifies waiving notice
and comment prior to adoption of this
rule because the risk of having a
degraded transducer is higher with units
that have more than 7,500 total flight
hours accumulated. Degraded AOA
transducers can result in inaccurate
activation of the stall warning, stick
shaker, or stick pusher, which could
result in ineffective response to
aerodynamic stall. Therefore, we
determined that notice and opportunity
for public comment before issuing this
AD are impracticable and that good
cause exists for making this amendment
effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and
opportunity for public comment. We
invite you to send any written relevant
data, views, or arguments about this AD.
Send your comments to an address
listed under the ADDRESSES section.
Include ‘‘Docket No. FAA–2009–0130;
Directorate Identifier 2008–NM–225–
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.
We will post all comments we
receive, without change, to https://
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,
VerDate Nov<24>2008
16:40 Feb 19, 2009
Jkt 217001
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 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.

Effective Date
(a) This airworthiness directive (AD)
becomes effective March 9, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier Model
CL–600–2B19 (Regional Jet Series 100 & 440)
airplanes, serial number 7003 and
subsequent, certificated in any category, that
are equipped with Thales angle of attack
(AOA) transducers having part number
45150340 or C16258AA.
Subject
(d) Air Transport Association (ATA) of
America Code 27: Flight controls.
Reason
(e) The mandatory continued airworthiness
information (MCAI) states:
The heating capability of several Angle Of
Attack (AOA) transducer heating elements
removed from in-service aircraft have been
found to be below the minimum requirement.
Also, it was discovered that a large number
of AOA transducers repaired in an approved
maintenance facility were not calibrated
accurately.
Inaccurate calibration of the AOA
transducer and/or degraded AOA transducer
heating elements can result in early or late
activation of the stall warning, stick shaker
and stick pusher by the Stall Protection
Computer (SPC).
This [Canadian] directive mandates a
periodic inspection of the inrush current to
verify the AOA heating capability and
replacement of the inaccurately calibrated
AOA transducers.
The unsafe condition is reduced
controllability of the airplane.
Actions and Compliance
(f) Unless already done, do the following
actions:
(1) For airplanes equipped with a
transducer having accumulated more than
7,500 total flight hours as of the effective date

FAA AD Differences
Note 1: This AD differs from the MCAI
and/or service information as follows: This
AD does not require the following actions
specified in the MCAI: the one-time
inspection for serial numbers and oncondition replacement in Paragraph 1. of the
MCAI, and the initial inspection compliance
times for transducers with 7,500 or fewer
flight hours as of the effective date of this AD
in Paragraph 2. of the MCAI. The planned
compliance times for those actions would
allow enough time to provide notice and
opportunity for prior public comment on the
merits of those actions. Therefore, we are
considering further rulemaking to address
this issue.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, New York Aircraft
Certification Office (ACO), FAA, has the
authority to approve AMOCs for this AD, if

(516) 794–5531. Before using any approved
AMOC on any airplane to which the AMOC
applies, notify your principal maintenance
inspector (PMI) or principal avionics
inspector, as appropriate, or lacking a
principal inspector, your local Flight
Standards District Office.
(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 FAAapproved 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,
the Office of Management and Budget (OMB)
has approved the information collection
requirements and has assigned OMB Control
Number 2120–0056.

One operator experienced failures of four
Fuel Level Sensor-Amplifier (FLSA) and
Multi Tank Indicators (MTI) units. FLSA and
MTI failures have been identified as having
been caused by incorrect connector sleeves
material fitted to the MTI units.
Degradation of the electrical insulation
sleeves of the Low-level indication lamps on
the MTI on the flight deck can cause a short
circuit that might result in high voltage being
conveyed to the high and low level sensors
in the outer tanks. This might cause the level
sensor to heat above acceptable limits.
For the reasons stated above, this
Airworthiness Directive (AD) requires the
accomplishment of wiring modifications to
protect the FLSA and the Flight Warning

Actions Since NPRM Was Issued
Since we issued the NPRM, Airbus
has issued Mandatory Service Bulletin
A300–28A6096, Revision 02, dated July
4, 2008. In the NPRM, we referred to
Airbus Mandatory Service Bulletin
A300–28A6096, Revision 01, dated
April 16, 2008, as the source of service
information for doing the modification.
The procedures in Airbus Mandatory
Service Bulletin A300–28A6096,
Revision 02, dated July 4, 2008, are
essentially the same as those in Airbus
Mandatory Service Bulletin A300–
28A6096, Revision 01, dated April 16,
2008. Therefore, we have revised
paragraph (f) of this AD to refer to
Airbus Mandatory Service Bulletin
A300–28A6096, Revision 02, dated July
4, 2008, as the appropriate source of
service information for doing the
modification, and to give credit for
using Airbus Mandatory Service
Bulletin A300–28A6096, Revision 01,
dated April 16, 2008, for accomplishing
the modification before the effective
date of the AD.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received.
Request To Delay Issuance of AD
Air Transport Association (ATA), on
behalf of its member American Airlines
(AA), and UPS and FedEx ask that we
delay issuance of the AD until the
master minimum equipment list
(MMEL) can be revised to support the
low-level warning configuration. AA,
UPS, and FedEx state that disconnection
of the low-level warning for the left and
right outer fuel tanks requires
significant changes to the Airbus A300–
600 MMEL. AA, UPS, and FedEx add
that the current MMEL available to U.S.
operators cannot support the
disconnected low-level warning
configuration; therefore, the AD should
not be released until the MMEL has
been revised.
We disagree with the commenter’s
request and rationale for delaying
issuance of the AD. Revision 16 of the
MMEL, dated October 2008, has been
released and is available to U.S.
operators. Revision 16 of the MMEL
supports the low-level warning

ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
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:
The heating capability of several Angle Of Attack (AOA)
transducer heating elements removed from in-service aircraft have
been found to be below the minimum requirement. Also, it was
discovered that a large number of AOA transducers repaired in an
approved maintenance facility were not calibrated accurately.
Inaccurate calibration of the AOA transducer and/or degraded AOA
transducer heating elements can result in early or late activation
of the stall warning, stick shaker and stick pusher by the Stall
Protection Computer (SPC).
* * * * *
The unsafe condition is reduced controllability of the airplane.
This AD requires actions that are intended to address the unsafe
condition described in the MCAI.
DATES: This AD becomes effective March 9, 2009.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of March 9,
2009.

SUPPLEMENTARY INFORMATION:
Discussion
The Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2008-35, dated December 22, 2008 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
The heating capability of several Angle Of Attack (AOA)
transducer heating elements removed from in-service aircraft have
been found to be below the minimum requirement. Also, it was
discovered that a large number of AOA transducers repaired in an
approved maintenance facility were not calibrated accurately.
Inaccurate calibration of the AOA transducer and/or degraded AOA
transducer heating elements can result in early or late activation
of the stall warning, stick shaker and stick pusher by the Stall
Protection Computer (SPC).
This [Canadian] directive mandates a periodic inspection of the
inrush current to verify the AOA heating capability and replacement
of the inaccurately calibrated AOA transducers.
The unsafe condition is reduced controllability of the airplane. You
may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Service Bulletin 601R-27-153, Revision A,
dated December 16, 2008. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI.
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 MCAI and service
information referenced above. We are issuing this AD because we
evaluated all pertinent information and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Differences Between the 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
[[Page 7790]]
MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the AD.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because the
risk of having a degraded transducer is higher with units that have
more than 7,500 total flight hours accumulated. Degraded AOA
transducers can result in inaccurate activation of the stall warning,
stick shaker, or stick pusher, which could result in ineffective
response to aerodynamic stall. Therefore, we determined that notice and
opportunity for public comment before issuing this AD are impracticable
and that good cause exists for making this amendment effective in fewer
than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2009-0130; Directorate
Identifier 2008-NM-225-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.
We will post all comments we receive, without change, to https://
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 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.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2009-04-11 Bombardier, Inc. (Formerly Canadair): Amendment 39-15817.
Docket No. FAA-2009-0130; Directorate Identifier 2008-NM-225-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective March 9,
2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) airplanes, serial number 7003 and subsequent,
certificated in any category, that are equipped with Thales angle of
attack (AOA) transducers having part number 45150340 or C16258AA.
Subject
(d) Air Transport Association (ATA) of America Code 27: Flight
controls.
Reason
(e) The mandatory continued airworthiness information (MCAI)
states:
The heating capability of several Angle Of Attack (AOA)
transducer heating elements removed from in-service aircraft have
been found to be below the minimum requirement. Also, it was
discovered that a large number of AOA transducers repaired in an
approved maintenance facility were not calibrated accurately.
Inaccurate calibration of the AOA transducer and/or degraded AOA
transducer heating elements can result in early or late activation
of the stall warning, stick shaker and stick pusher by the Stall
Protection Computer (SPC).
This [Canadian] directive mandates a periodic inspection of the
inrush current to verify the AOA heating capability and replacement
of the inaccurately calibrated AOA transducers.
The unsafe condition is reduced controllability of the airplane.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) For airplanes equipped with a transducer having accumulated
more than 7,500 total flight hours as of the effective date of this
AD: Within 250 flight hours after the effective date of this AD,
measure the inrush current of both AOA transducers in accordance
with Part A of the Accomplishment Instructions of Bombardier Service
Bulletin 601R-27-153, Revision A, dated December 16, 2008.
(i) If both AOA transducers are found to have an inrush current
of 1.60 amps or more, repeat the measurement thereafter at intervals
not to exceed the applicable interval specified in Table 1 of this
AD. Do the measurement in accordance with Part A of the
Accomplishment Instructions of Bombardier Service Bulletin 601R-27-
153, Revision A, dated December 16, 2008.

accordance with Bombardier Service Bulletin 601R-27-153, dated
October 17, 2008, are acceptable for compliance with the
corresponding requirements of paragraphs (f)(1) and (f)(2) of this
AD.
FAA AD Differences
Note 1: This AD differs from the MCAI and/or service information
as follows: This AD does not require the following actions specified
in the MCAI: the one-time inspection for serial numbers and on-
condition replacement in Paragraph 1. of the MCAI, and the initial
inspection compliance times for transducers with 7,500 or fewer
flight hours as of the effective date of this AD in Paragraph 2. of
the MCAI. The planned compliance times for those actions would allow
enough time to provide notice and opportunity for prior public
comment on the merits of those actions. Therefore, we are
considering further rulemaking to address this issue.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft Certification Office (ACO), FAA, has the authority to
approve AMOCs for this AD, if requested using the procedures found
in 14 CFR 39.19. Send information to ATTN: Wing Chan, Aerospace
Engineer, Systems and Flight Test Branch, ANE-172, FAA, New York
Aircraft Certification Office, 1600 Stewart Avenue, Suite 410,
Westbury, New York 11590; telephone (516) 228-7311; fax (516) 794-
5531. Before using any approved AMOC on any airplane to which the
AMOC applies, notify your principal maintenance inspector (PMI) or
principal avionics inspector, as appropriate, or lacking a principal
inspector, your local Flight Standards District Office.
(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, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
