subspecies of sweet oranges, did not
evaluate disease transmission from
seeds taken from asymptomatic fruit,
and was aborted before conclusive
findings could be drawn. The
commenter therefore asserted that seed
should not be regulated as a host of CVC
until further research is conducted.
The commenter is right in pointing
out that Li et al. was aborted abruptly,
because of a hurricane, and that only a
study on three subspecies of sweet
oranges was concluded by that time.
However, CVC seed infection rates were
greater than 22 percent for one
subspecies evaluated in that study, and
the transmission from seeds to seedlings
was determined to be ‘‘efficient.’’
Moreover, research had begun on
several other species, and was tending
towards the results of the sweet orange
study. Finally, we note that no studies
have been conducted since 2003 that
call into question the findings of Li
et al. For these reasons, we have
determined that Li et al.’s conclusion,
that the study ‘‘demonstrated that [CVC]
can be transmitted through seed to
seedlings,’’ is correct, and constitutes a
sufficient basis for the prohibitions in
the interim rule.
Therefore, for the reasons given in the
interim rule and in this document, we
are adopting the interim rule as a final
rule, without change.
This action also affirms the
information contained in the interim
rule concerning Executive Order 12988
and the Paperwork Reduction Act.
Further, this action has been
determined to be not significant for the
purposes of Executive Order 12866 and,
therefore, has not been reviewed by the
Office of Management and Budget.

Regulatory Flexibility Act
This rule affirms an interim rule that
amended the regulations governing the
importation of nursery stock to prohibit
the importation of propagative seed of
several Rutaceae (citrus family) genera
from certain countries where citrus
greening or citrus variegated chlorosis
(CVC) is present. The interim rule also
required propagative seed of these
genera from all other countries to be
accompanied by a phytosanitary
certificate with an additional
declaration that neither citrus greening
nor CVC are known to occur in the
country where the seed was produced.
The action was necessary in order to
prevent the introduction or
dissemination of citrus greening or CVC
within the United States.
We have prepared a final regulatory
flexibility analysis addressing the
economic effects of the interim rule on
small entities, as required by the

ACTION: Final rule.
AGENCY:
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:
During flight-testing of a wing anti-ice
piccolo tube containing a deliberate small
breach, it was determined that the wing
leading edge thermal switches Part Number
(P/N) 601R59320–1 were not detecting the
consequent bleed leak at the design

threshold. As a result, Airworthiness
Limitation (AWL) tasks, consisting of a
functional check of the wing leading edge
thermal switches (P/N 601R59320–1) and an
inspection of the wing anti-ice duct piccolo
tubes on aeroplanes with these switches
installed, have been introduced. These tasks
will limit exposure to dormant failure of the
wing leading edge thermal switches in the
event of piccolo tube failure, which could
potentially compromise the structural
integrity of the wing leading edge and the
effectiveness of the wing anti-ice system.

The unsafe condition is loss of control
of the airplane. We are issuing this AD
to require actions to correct the unsafe
condition on these products.

March 22, 2011.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of March 22, 2011.

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 November 15, 2010 (75 FR
69609). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
During flight-testing of a wing anti-ice

This directive mandates revision of the
approved maintenance schedule to include
the above referenced tasks, including phasein schedules that supersede the phase-in
schedules specified in the AWL tasks.
Note: Thermal switches, P/N 601R59320–
1, were installed in production on aircraft
Serial Numbers (S/N) 7213 and subsequent.
Service Bulletin 601R–30–022 covered inservice installation of these switches on
aircraft S/Ns 7003 through 7212.
The unsafe condition is loss of control
of the airplane. You may obtain further
information by examining the MCAI in
the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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.

Costs of Compliance
We estimate that this AD will affect
628 products of U.S. registry. We also
estimate that it will take about 1 workhour 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 this AD to the U.S. operators to
be $53,380, 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,
VerDate Mar<15>2010
15:22 Feb 14, 2011
Jkt 223001
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.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://
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

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:
During flight-testing of a wing anti-ice piccolo tube containing
a deliberate small breach, it was determined that the wing leading
edge thermal switches Part Number (P/N) 601R59320-1 were not
detecting the consequent bleed leak at the design threshold. As a
result, Airworthiness Limitation (AWL) tasks, consisting of a
functional check of the wing leading edge thermal switches (P/N
601R59320-1) and an inspection of the wing anti-ice duct piccolo
tubes on aeroplanes with these switches installed, have been
introduced. These tasks will limit exposure to dormant failure of
the wing leading edge thermal switches in the event of piccolo tube
failure, which could potentially compromise the structural integrity
of the wing leading edge and the effectiveness of the wing anti-ice
system.
* * * * *
The unsafe condition is loss of control of the airplane. We are issuing
this AD to require actions to correct the unsafe condition on these
products.

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 November 15, 2010
(75 FR 69609). That NPRM proposed to correct an unsafe condition for
the specified products. The MCAI states:
During flight-testing of a wing anti-ice piccolo tube containing
a deliberate small breach, it was determined that the wing leading
edge thermal switches Part Number (P/N) 601R59320-1 were not

the wing leading edge thermal switches in the event of piccolo tube
failure, which could potentially compromise the structural integrity
of the wing leading edge and the effectiveness of the wing anti-ice
system.
[[Page 8606]]
This directive mandates revision of the approved maintenance
schedule to include the above referenced tasks, including phase-in
schedules that supersede the phase-in schedules specified in the AWL
tasks.
Note: Thermal switches, P/N 601R59320-1, were installed in
production on aircraft Serial Numbers (S/N) 7213 and subsequent.
Service Bulletin 601R-30-022 covered in-service installation of
these switches on aircraft S/Ns 7003 through 7212.
The unsafe condition is loss of control of the airplane. You may obtain
further information by examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
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.
Costs of Compliance
We estimate that this AD will affect 628 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
this AD to the U.S. operators to be $53,380, 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.
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 https://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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
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:
2011-04-03 Bombardier, Inc.: Amendment 39-16603. Docket No. FAA-
2010-1113; Directorate Identifier 2010-NM-121-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective March
22, 2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 and 440) airplanes; certificated in any
category; serial numbers 7003 and subsequent.
Subject
(d) Air Transport Association (ATA) of America Code 57: Wings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During flight-testing of a wing anti-ice piccolo tube containing
a deliberate small breach, it was determined that the wing leading
edge thermal switches Part Number (P/N) 601R59320-1 were not
detecting the consequent bleed leak at the design threshold. As a
result, Airworthiness Limitation (AWL) tasks, consisting of a
functional check of the wing leading edge thermal switches (P/N
601R59320-1) and an inspection of the wing anti-ice duct piccolo
tubes on aeroplanes with these switches installed, have been
introduced. These tasks will limit exposure to dormant failure of
the wing leading edge thermal switches in the event of piccolo tube
failure, which could potentially compromise the structural integrity
of the wing leading edge and the effectiveness of the wing anti-ice
system.
* * * * *
The unsafe condition is loss of control of the airplane.
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) Within 30 days after the effective date of this AD, revise
the Airworthiness Limitations section (ALS) of the maintenance
program by incorporating Task C36-20-133-03 specified in Bombardier
Temporary Revision (TR) 2A-50, dated November 17, 2009; and Task
C30-10-133-01 specified in Bombardier TR 2A-49, dated November 17,
2009; into Appendix A, ``Certification Maintenance Requirements,''
of Part 2 of the
[[Page 8607]]
Bombardier CL-600-2B19 Maintenance Requirements Manual (MRM). For
these tasks, the initial compliance time starts at the applicable
time specified in paragraphs (g)(1) and (g)(2) of this AD.
Thereafter, except as provided by paragraph (h) of this AD, no
alternative functional check of the thermal switch or detailed
visual inspection of the piccolo tube may be approved.
Note 1: The actions required by paragraph (g) of this AD may be
done by inserting a copy of Bombardier TR 2A-49 and TR 2A-50, both
dated November 17, 2009, into the Appendix A of Part 2 of the
Bombardier CL-600-2B19 MRM. When these TRs have been included in
Appendix A of Part 2 of the general revisions of the MRM, the
general revisions may be inserted in the MRM, provided that the
relevant information in the general revision is identical to that in
Bombardier TR 2A-49 and TR 2A-50, both dated November 17, 2009.
(1) For Task C36-20-133-03, the initial compliance time is
before the accumulation of 15,000 total flight hours or within 7
months after the effective date of this AD, whichever occurs later.
(2) For Task C30-10-133-01, the initial compliance time is
before the accumulation of 15,000 total flight hours on the piccolo
tube or within 7 months after the effective date of this AD,
whichever occurs later.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service
information as follows: No differences.
Other FAA AD Provisions
(h) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft Certification Office (ACO), ANE-170, 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: Program
Manager, Continuing Operational Safety, FAA, New York ACO, 1600
Stewart Avenue, Suite 410, Westbury, New York, 11590; telephone 516-
228-7300; fax 516-794-5531. Before using any approved AMOC, notify
your appropriate principal inspector, or lacking a principal
inspector, the manager of the local flight standards district
office/certificate holding 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: A federal agency may not conduct or
sponsor, and a person is not required to respond to, nor shall a
person be subject to a penalty for failure to comply with a
collection of information subject to the requirements of the
Paperwork Reduction Act unless that collection of information
displays a current valid OMB Control Number. The OMB Control Number
for this information collection is 2120-0056. Public reporting for
this collection of information is estimated to be approximately 5
minutes per response, including the time for reviewing instructions,
completing and reviewing the collection of information. All
responses to this collection of information are mandatory. Comments
concerning the accuracy of this burden and suggestions for reducing
the burden should be directed to the FAA at: 800 Independence Ave.,
