Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are superseding Airworthiness Directive (AD) 2008–08– 09 for certain Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. AD 2008–08–09 required revising the airworthiness limitations (AWL) section of the Instructions for Continued Airworthiness by incorporating procedures for repetitive functional tests of the pilot input lever of the pitch feel simulator (PFS) units and corrective actions if necessary. This new AD requires replacing certain PFS units with new redesigned PFS units, which would terminate the repetitive functional tests; and both adding and removing certain airplanes from the applicability. This AD was prompted by reports that the shear pin in the input lever of several PFS units failed due to fatigue; and by the development of a redesigned PFS unit, which eliminates the need for repetitive functional tests. We are issuing this AD to prevent undetected failure of the shear pins of both PFS units simultaneously, which could result in loss of pitch feel forces and consequent reduced control of the airplane. DATES: This AD becomes effective August 19, 2014. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 19, 2014.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2008–08–09, Amendment 39–15461 (73 FR 19979, April 14, 2008). AD 2008–08–09 applied to certain Bombardier, Inc. Model CL– 600–2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM published in the Federal Register on April 9, 2013 (78 FR 21074). Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2005–41R1, dated May 10, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: wreier-aviles on DSK5TPTVN1PROD with RULES The shear pin in the input lever of several Pitch Feel Simulators (PFS) units has failed due to fatigue. The shear pin failure is not always detectable by the flight crew in normal operation. Failure of the shear pins in both PFS units on an aeroplane could result in loss of pitch feel forces and reduced controllability of the aeroplane. Recently, Transport Canada has certified the new design of the PFS unit—part number (P/N) 601R92300–7 as a terminating action. Revision 1 of this [Canadian] AD mandates the retrofit of all in-service CL–600–2B19 aeroplanes with the redesigned PFS unit. Required actions include revising the AWLs section of the Instructions for Continued Airworthiness, repetitive functional testing of the pilot input lever of the PFS unit, and corrective actions if necessary, and replacing the PFS units having part number (P/N) 601R92300–3 (vendor P/N TY1910– 50A) or 601R92300–5 (vendor P/N TY1910–51A) with PFS units having P/N 601R92300–7 (vendor P/N TY1910– 54A), which terminates the actions required by AD 2008–08–09, Amendment 39–15461 (73 FR 19979, April 14, 2008). This AD also adds airplanes having serial numbers (S/Ns) VerDate Mar<15>2010 15:12 Jul 14, 2014 Jkt 232001 7991 through 7999 inclusive, and removes airplanes having S/Ns 8111 and subsequent. You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/ #!docketDetail;D=FAA-2013-0296. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (78 FR 21074, April 9, 2013) and the FAA’s response to each comment. Request To Revise the Applicability by Adding Part Numbers Air Wisconsin Airlines Corporation (Air Wisconsin) requested that we revise paragraph (c) of the proposed AD (78 FR 21074, April 9, 2013) by adding the part numbers of the PFS units, in addition to the airplane serial numbers. Air Wisconsin stated that the part numbers that should be added are P/N 601R92300–3 (vendor P/N TY1910– 50A) and P/N 601R92300–5 (vendor P/N TY1910–51A). Air Wisconsin provided no justification for this request. We do not agree to add the requested part numbers to the applicability of this AD. The functional check of the input lever required by this AD must be done on all airplanes having the serial numbers identified in the applicability of this AD. We have made no changes to paragraph (c) of this AD in this regard. Request To Clarify Instructions Regarding Airworthiness Limitations Air Wisconsin requested that we clarify how an operator is to update the AWLs when the task for doing the functional test of the PFS unit was deleted. Air Wisconsin stated that paragraph (g) of the proposed AD (78 FR 21074, April 9, 2013) refers to Task R27–31–A024–01, which was deleted by Bombardier on February 23, 2007. Air Wisconsin pointed out that Task R27– 31–A024–01 was specified in Bombardier Temporary Revision (TR) 2B–1784, dated October 24, 2003, to the Canadair CL–600–2B19 Regional Jet Maintenance Requirements Manual, Part 2, Appendix B, which is no longer available or relevant. We agree. We removed proposed paragraph (g) (78 FR 21074, April 9, 2013) from this AD, and redesignated subsequent paragraphs accordingly. The functional test specified in paragraph (h) of the proposed AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (g) of this AD) is now required in paragraph (g) of this AD. PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 41105 Request To Revise Applicability To Exclude a Certain Serial Number Air Wisconsin requested that we revise paragraph (h) of the proposed AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (g) of this AD) to match the Effectivity section of Bombardier Alert Service Bulletin A601R–27–144, Revision E, dated October 2, 2012. Air Wisconsin stated that paragraph (h) of the proposed AD applies to airplanes having S/Ns 7003 through 7990 inclusive, and S/Ns 8000 through 8111 inclusive. Air Wisconsin stated that, while the Effectivity section of the service information varies between revisions, Bombardier Alert Service Bulletin A601R–27–144, Revision E, dated October 2, 2012, excludes the airplane having S/N 8111. We agree with Air Wisconsin’s request to revise the applicability of this final rule for the reason provided. We have confirmed that the airplane having S/N 8111 is not affected by the unsafe condition addressed by this AD. Therefore, we have revised paragraphs (c) and (g) of this AD (designated as paragraphs (c) and (h) of the proposed AD (78 FR 21074, April 9, 2013)) to remove the airplane having S/N 8111. We have coordinated this change with TCCA and Bombardier. Request To Clarify Instructions Regarding Functional Test Air Wisconsin requested that we clarify how an operator is to perform the functional test identified in paragraph (j) of the proposed AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (i) of this AD) when the task for the functional test has been deleted. Air Wisconsin stated that paragraph (j) of the proposed AD refers to Task R27– 31–A024–01, which was deleted by Bombardier on February 23, 2007. Air Wisconsin stated that this task was specified in Bombardier TR 2B–1784, dated October 24, 2003, to the Canadair CL–600–2B19 Regional Jet Maintenance Requirements Manual, Part 2, Appendix B, which is no longer available or relevant. We agree for the reason stated by Air Wisconsin. We have revised paragraph (i) of this AD (designated as paragraph (j) in the proposed AD (78 FR 21074, April 9, 2013)) by removing the reference to Task R27–31–A024–01. Request To Revise Wording in Paragraph (k) of the Proposed AD (78 FR 21074, April 9, 2013) Air Wisconsin requested that the term ‘‘detected’’ in paragraph (k) of the proposed AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (j) of E:\FR\FM\15JYR1.SGM 15JYR1 41106 Federal Register / Vol. 79, No. 135 / Tuesday, July 15, 2014 / Rules and Regulations this AD) be changed to ‘‘disconnected.’’ Air Wisconsin asserted that FAA’s intent was probably to use the term ‘‘disconnected.’’ We partially agree. We agree that paragraph (j) of this AD (78 FR 21074, April 9, 2013) (designated as paragraph (k) of the proposed AD) should read differently. Paragraph 2.B.(4)(c) of the Accomplishment Instructions of Bombardier Service Bulletin A601R–27– 144, Revision E, dated October 2, 2012, states, ‘‘If the input lever moves freely, or the input lever is loose, the PFS is ‘‘defective. . . .’’ Therefore, we have revised paragraphs (i) and (j) of this AD (designated as paragraphs (j) and (k) of the proposed AD) by changing the word ‘‘disconnected’’ to ‘‘defective.’’ wreier-aviles on DSK5TPTVN1PROD with RULES Request To Clarify Airplanes Affected by New PFS Unit Replacement Air Wisconsin requested that paragraph (l) of the proposed AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (k) of this AD) be revised to add vendor P/Ns TY1910–50A, TY1910–51A, and TY1910–54A for clarity. We agree with Air Wisconsin’s request to add vendor part numbers in paragraph (k) of this AD (designated as paragraph (l) in the proposed AD (78 FR 21074, April 9, 2013). We have revised paragraph (k) of this AD by adding the vendor part numbers with the manufacturer part numbers. We have added new paragraph (l)(1) to this AD. Paragraph (l)(1) of this AD gives credit for doing a functional test if done before the effective date of AD 2006–05–11 R1, Amendment 39–14528 (71 FR 15323, March 28, 2006), using Bombardier Alert Service Bulletin A601R–27–144, including Appendix A, dated September 15, 2005. We redesignated paragraphs (m)(1), (m)(1)(i), (m)(1)(ii), and (m)(2) of the proposed AD (78 FR 21074, April 9, 2013) as paragraphs (l)(2), (l)(2)(i), (l)(2)(ii), and (l)(5) of this AD. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 21074, April 9, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 21074, April 9, 2013). Request To Add Compliance Time When Total Flight Hours are Unknown Air Wisconsin requested that paragraph (l) of the proposed AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (k) of this AD) be revised to add a replacement compliance time for PFS units on which the total flight hours are unknown. Air Wisconsin suggested the compliance time for PFS units with unknown total flight hours be 3,000 flight hours or 18 months after the effective date of this AD. We agree with Air Wisconsin’s request to specify a compliance time for PFS units with unknown total flight hours. We have revised paragraph (k)(4) of this AD (78 FR 21074, April 9, 2013) to add the suggested compliance time for PFS units having P/N 601R92300–3 (vendor P/N TY1910–50A) or 601R92300–5 (vendor P/N TY1910– 51A) for which the total flight hours are unknown or cannot be determined. Costs of Compliance We estimate that this AD affects 574 airplanes of U.S. registry. The actions that are required by AD 2008–08–09, Amendment 39–15461 (73 FR 19979, April 14, 2008), and retained in this AD take about 2 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost $0 per product. Based on these figures, the estimated cost of the actions that were required by AD 2008–08–09 is $170 per product. We also estimate that it will take about 8 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $2,500 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD on U.S. operators to be $1,825,320, or $3,180 per product. Explanation of Changes Made to This AD We have reformatted paragraph (l) of this AD (designated as paragraph (m) of the proposed AD (78 FR 21074, April 9, 2013). 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: VerDate Mar<15>2010 15:12 Jul 14, 2014 Jkt 232001 PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 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 that 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); 3. Will not affect intrastate aviation in Alaska; and 4. 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.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2008-08-09 for 
certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 
440) airplanes. AD 2008-08-09 required revising the airworthiness 
limitations (AWL) section of the Instructions for Continued 
Airworthiness by incorporating procedures for repetitive functional 
tests of the pilot input lever of the pitch feel simulator (PFS) units 
and corrective actions if necessary. This new AD requires replacing 
certain PFS units with new redesigned PFS units, which would terminate 
the repetitive functional tests; and both adding and removing certain 
airplanes from the applicability. This AD was prompted by reports that 
the shear pin in the input lever of several PFS units failed due to 
fatigue; and by the development of a re-designed PFS unit, which 
eliminates the need for repetitive functional tests. We are issuing 
this AD to prevent undetected failure of the shear pins of both PFS 
units simultaneously, which could result in loss of pitch feel forces 
and consequent reduced control of the airplane.

DATES: This AD becomes effective August 19, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 19, 
2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2008-08-09, Amendment 39-15461 (73 FR 19979, 
April 14, 2008). AD 2008-08-09 applied to certain Bombardier, Inc. 
Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM 
published in the Federal Register on April 9, 2013 (78 FR 21074).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2005-41R1, dated May 10, 2012 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    The shear pin in the input lever of several Pitch Feel 
Simulators (PFS) units has failed due to fatigue. The shear pin 
failure is not always detectable by the flight crew in normal 
operation. Failure of the shear pins in both PFS units on an 
aeroplane could result in loss of pitch feel forces and reduced 
controllability of the aeroplane.
    Recently, Transport Canada has certified the new design of the 
PFS unit--part number (P/N) 601R92300-7 as a terminating action. 
Revision 1 of this [Canadian] AD mandates the retrofit of all in-
service CL-600-2B19 aeroplanes with the redesigned PFS unit.

Required actions include revising the AWLs section of the Instructions 
for Continued Airworthiness, repetitive functional testing of the pilot 
input lever of the PFS unit, and corrective actions if necessary, and 
replacing the PFS units having part number (P/N) 601R92300-3 (vendor P/
N TY1910-50A) or 601R92300-5 (vendor P/N TY1910-51A) with PFS units 
having P/N 601R92300-7 (vendor P/N TY1910-54A), which terminates the 
actions required by AD 2008-08-09, Amendment 39-15461 (73 FR 19979, 
April 14, 2008). This AD also adds airplanes having serial numbers (S/
Ns) 7991 through 7999 inclusive, and removes airplanes having S/Ns 8111 
and subsequent. You may examine the MCAI in the AD docket on the 
Internet at https://www.regulations.gov/#!docketDetail;D=FAA-2013-0296.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (78 
FR 21074, April 9, 2013) and the FAA's response to each comment.

Request To Revise the Applicability by Adding Part Numbers

    Air Wisconsin Airlines Corporation (Air Wisconsin) requested that 
we revise paragraph (c) of the proposed AD (78 FR 21074, April 9, 2013) 
by adding the part numbers of the PFS units, in addition to the 
airplane serial numbers. Air Wisconsin stated that the part numbers 
that should be added are P/N 601R92300-3 (vendor P/N TY1910-50A) and P/
N 601R92300-5 (vendor P/N TY1910-51A). Air Wisconsin provided no 
justification for this request.
    We do not agree to add the requested part numbers to the 
applicability of this AD. The functional check of the input lever 
required by this AD must be done on all airplanes having the serial 
numbers identified in the applicability of this AD. We have made no 
changes to paragraph (c) of this AD in this regard.

Request To Clarify Instructions Regarding Airworthiness Limitations

    Air Wisconsin requested that we clarify how an operator is to 
update the AWLs when the task for doing the functional test of the PFS 
unit was deleted. Air Wisconsin stated that paragraph (g) of the 
proposed AD (78 FR 21074, April 9, 2013) refers to Task R27-31-A024-01, 
which was deleted by Bombardier on February 23, 2007. Air Wisconsin 
pointed out that Task R27-31-A024-01 was specified in Bombardier 
Temporary Revision (TR) 2B-1784, dated October 24, 2003, to the 
Canadair CL-600-2B19 Regional Jet Maintenance Requirements Manual, Part 
2, Appendix B, which is no longer available or relevant.
    We agree. We removed proposed paragraph (g) (78 FR 21074, April 9, 
2013) from this AD, and redesignated subsequent paragraphs accordingly. 
The functional test specified in paragraph (h) of the proposed AD (78 
FR 21074, April 9, 2013) (redesignated as paragraph (g) of this AD) is 
now required in paragraph (g) of this AD.

Request To Revise Applicability To Exclude a Certain Serial Number

    Air Wisconsin requested that we revise paragraph (h) of the 
proposed AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (g) 
of this AD) to match the Effectivity section of Bombardier Alert 
Service Bulletin A601R-27-144, Revision E, dated October 2, 2012. Air 
Wisconsin stated that paragraph (h) of the proposed AD applies to 
airplanes having S/Ns 7003 through 7990 inclusive, and S/Ns 8000 
through 8111 inclusive. Air Wisconsin stated that, while the 
Effectivity section of the service information varies between 
revisions, Bombardier Alert Service Bulletin A601R-27-144, Revision E, 
dated October 2, 2012, excludes the airplane having S/N 8111.
    We agree with Air Wisconsin's request to revise the applicability 
of this final rule for the reason provided. We have confirmed that the 
airplane having S/N 8111 is not affected by the unsafe condition 
addressed by this AD. Therefore, we have revised paragraphs (c) and (g) 
of this AD (designated as paragraphs (c) and (h) of the proposed AD (78 
FR 21074, April 9, 2013)) to remove the airplane having S/N 8111. We 
have coordinated this change with TCCA and Bombardier.

Request To Clarify Instructions Regarding Functional Test

    Air Wisconsin requested that we clarify how an operator is to 
perform the functional test identified in paragraph (j) of the proposed 
AD (78 FR 21074, April 9, 2013) (redesignated as paragraph (i) of this 
AD) when the task for the functional test has been deleted. Air 
Wisconsin stated that paragraph (j) of the proposed AD refers to Task 
R27-31-A024-01, which was deleted by Bombardier on February 23, 2007. 
Air Wisconsin stated that this task was specified in Bombardier TR 2B-
1784, dated October 24, 2003, to the Canadair CL-600-2B19 Regional Jet 
Maintenance Requirements Manual, Part 2, Appendix B, which is no longer 
available or relevant.
    We agree for the reason stated by Air Wisconsin. We have revised 
paragraph (i) of this AD (designated as paragraph (j) in the proposed 
AD (78 FR 21074, April 9, 2013)) by removing the reference to Task R27-
31-A024-01.

Request To Revise Wording in Paragraph (k) of the Proposed AD (78 FR 
21074, April 9, 2013)

    Air Wisconsin requested that the term ``detected'' in paragraph (k) 
of the proposed AD (78 FR 21074, April 9, 2013) (redesignated as 
paragraph (j) of

[[Page 41106]]

this AD) be changed to ``disconnected.'' Air Wisconsin asserted that 
FAA's intent was probably to use the term ``disconnected.''
    We partially agree. We agree that paragraph (j) of this AD (78 FR 
21074, April 9, 2013) (designated as paragraph (k) of the proposed AD) 
should read differently. Paragraph 2.B.(4)(c) of the Accomplishment 
Instructions of Bombardier Service Bulletin A601R-27-144, Revision E, 
dated October 2, 2012, states, ``If the input lever moves freely, or 
the input lever is loose, the PFS is ``defective. . . .'' Therefore, we 
have revised paragraphs (i) and (j) of this AD (designated as 
paragraphs (j) and (k) of the proposed AD) by changing the word 
``disconnected'' to ``defective.''

Request To Clarify Airplanes Affected by New PFS Unit Replacement

    Air Wisconsin requested that paragraph (l) of the proposed AD (78 
FR 21074, April 9, 2013) (redesignated as paragraph (k) of this AD) be 
revised to add vendor P/Ns TY1910-50A, TY1910-51A, and TY1910-54A for 
clarity.
    We agree with Air Wisconsin's request to add vendor part numbers in 
paragraph (k) of this AD (designated as paragraph (l) in the proposed 
AD (78 FR 21074, April 9, 2013). We have revised paragraph (k) of this 
AD by adding the vendor part numbers with the manufacturer part 
numbers.

Request To Add Compliance Time When Total Flight Hours are Unknown

    Air Wisconsin requested that paragraph (l) of the proposed AD (78 
FR 21074, April 9, 2013) (redesignated as paragraph (k) of this AD) be 
revised to add a replacement compliance time for PFS units on which the 
total flight hours are unknown. Air Wisconsin suggested the compliance 
time for PFS units with unknown total flight hours be 3,000 flight 
hours or 18 months after the effective date of this AD.
    We agree with Air Wisconsin's request to specify a compliance time 
for PFS units with unknown total flight hours. We have revised 
paragraph (k)(4) of this AD (78 FR 21074, April 9, 2013) to add the 
suggested compliance time for PFS units having P/N 601R92300-3 (vendor 
P/N TY1910-50A) or 601R92300-5 (vendor P/N TY1910-51A) for which the 
total flight hours are unknown or cannot be determined.

Explanation of Changes Made to This AD

    We have reformatted paragraph (l) of this AD (designated as 
paragraph (m) of the proposed AD (78 FR 21074, April 9, 2013).
    We have added new paragraph (l)(1) to this AD. Paragraph (l)(1) of 
this AD gives credit for doing a functional test if done before the 
effective date of AD 2006-05-11 R1, Amendment 39-14528 (71 FR 15323, 
March 28, 2006), using Bombardier Alert Service Bulletin A601R-27-144, 
including Appendix A, dated September 15, 2005.
    We redesignated paragraphs (m)(1), (m)(1)(i), (m)(1)(ii), and 
(m)(2) of the proposed AD (78 FR 21074, April 9, 2013) as paragraphs 
(l)(2), (l)(2)(i), (l)(2)(ii), and (l)(5) of this AD.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 21074, April 9, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 21074, April 9, 2013).

Costs of Compliance

    We estimate that this AD affects 574 airplanes of U.S. registry.
    The actions that are required by AD 2008-08-09, Amendment 39-15461 
(73 FR 19979, April 14, 2008), and retained in this AD take about 2 
work-hours per product, at an average labor rate of $85 per work-hour. 
Required parts cost $0 per product. Based on these figures, the 
estimated cost of the actions that were required by AD 2008-08-09 is 
$170 per product.
    We also estimate that it will take about 8 work-hours per product 
to comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $2,500 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $1,825,320, or $3,180 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 that 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

[[Page 41107]]

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 removing Airworthiness Directive (AD) 
2008-08-09, Amendment 39-15461 (73 FR 19979, April 14, 2008), and 
adding the following new AD:


2014-11-10 Bombardier: Amendment 39-17861. Docket No. FAA-2013-0296; 
Directorate Identifier 2012-NM-102-AD.

(a) Effective Date

    This AD becomes effective August 19, 2014.

(b) Affected ADs

    This AD supersedes AD 2008-08-09, Amendment 39-15461 (73 FR 
19979, April 14, 2008).

(c) Applicability

    This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional 
Jet Series 100 & 440) airplanes, certificated in any category, 
serial numbers (S/Ns) 7003 through 8110 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Reason

    This AD was prompted by reports that the shear pin in the input 
lever of several pitch feel simulator (PFS) units failed due to 
fatigue; and by the development of a re-designed PFS unit, which 
eliminates the need for repetitive functional testing. We are 
issuing this AD to prevent undetected failure of the shear pins of 
both PFS units simultaneously, which could result in loss of pitch 
feel forces and consequent reduced control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Functional Test of Input Lever With Revised Service 
Information

    This paragraph restates the requirements of paragraph (g) of AD 
2008-08-09, Amendment 39-15461 (73 FR 19979, April 14, 2008), with 
revised service information. For airplanes having S/Ns 7003 through 
7990 inclusive, and S/Ns 8000 through 8110 inclusive: Before the 
accumulation of 4,000 total flight hours, or within 100 flight hours 
after March 27, 2006 (the effective date of AD 2006-05-11 R1, 
Amendment 39-14528 (71 FR 15323, March 28, 2006), whichever occurs 
later, do a functional test of the pilot input lever of the PFS 
units to determine if the lever is disconnected, in accordance with 
the Accomplishment Instructions of a service bulletin specified in 
paragraph (g)(1), (g)(2), or (g)(3) of this AD. Repeat the test at
