Model BD–100–1A10 (Challenger 300) Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). 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: There has been an incident during a production flight test where the proximitysensor electronic unit (PSEU) failed. This resulted in unannunciated loss of: • Wheel brakes below 10 knots; • Thrust reverser; • Nose wheel steering; and • Auto-deployment of the multi-function spoilers. A similar condition, if not corrected, may result in reduced controllability of the aircraft upon landing and possible overrun of the runway. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective May 7, 2010. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 7, 2010.

SUPPLEMENTARY INFORMATION: ADDRESSES: 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 December 29, 2009 (74 FR 68741). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: There has been an incident during a production flight test where the proximitysensor electronic unit (PSEU) failed. This resulted in unannunciated loss of: • Wheel brakes below 10 knots; • Thrust reverser; • Nose wheel steering; and • Auto-deployment of the multi-function spoilers. A similar condition, if not corrected, may result in reduced controllability of the aircraft upon landing and possible overrun of the runway. The original issue of this [Canadian] directive mandated the introduction of nonnormal procedures to the airplane flight manual (AFM) as an interim corrective action to address PSEU failures. Revision 1 of this directive amends the aircraft applicability and introduces a note providing terminating action, for use at operator discretion, if the aircraft has incorporated a PSEU with software version 12 in accordance with Bombardier Service Bulletin (SB) 100–32–12. You may obtain further information by examining the MCAI in the AD docket. wwoods2 on DSK1DXX6B1PROD with RULES_PART 1 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. Explanation of Change Made to This AD We have revised this AD to identify the legal name of the manufacturer as published in the most recent type certificate data sheet for the affected airplane models. VerDate Nov<24>2008 12:54 Apr 01, 2010 Jkt 220001 Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD with the change described previously. We determined that this change 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 workhour 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 162 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 $13,770, 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 PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 16647 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.

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 December 29, 2009 
(74 FR 68741). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    There has been an incident during a production flight test where 
the proximity-sensor electronic unit (PSEU) failed. This resulted in 
unannunciated loss of:
     Wheel brakes below 10 knots;
     Thrust reverser;
     Nose wheel steering; and
     Auto-deployment of the multi-function spoilers.
    A similar condition, if not corrected, may result in reduced 
controllability of the aircraft upon landing and possible overrun of 
the runway.
    The original issue of this [Canadian] directive mandated the 
introduction of non-normal procedures to the airplane flight manual 
(AFM) as an interim corrective action to address PSEU failures.
    Revision 1 of this directive amends the aircraft applicability 
and introduces a note providing terminating action, for use at 
operator discretion, if the aircraft has incorporated a PSEU with 
software version 12 in accordance with Bombardier Service Bulletin 
(SB) 100-32-12.

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.

Explanation of Change Made to This AD

    We have revised this AD to identify the legal name of the 
manufacturer as published in the most recent type certificate data 
sheet for the affected airplane models.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the change described 
previously. We determined that this change 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 162 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 $13,770, 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.

2009-1214; Directorate Identifier 2009-NM-091-AD.

[[Page 16648]]

Effective Date

    (a) This airworthiness directive (AD) becomes effective May 7, 
2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Bombardier, Inc. Model BD-100-1A10 
(Challenger 300) airplanes, certificated in any category, serial 
numbers 20002 through 20153 inclusive.

Subject

    (d) Air Transport Association (ATA) of America Code 32: Landing 
gear.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    There has been an incident during a production flight test where 
the proximity-sensor electronic unit (PSEU) failed. This resulted in 
unannunciated loss of:
     Wheel brakes below 10 knots;
     Thrust reverser;
     Nose wheel steering; and
     Auto-deployment of the multi-function spoilers.
    A similar condition, if not corrected, may result in reduced 
controllability of the aircraft upon landing and possible overrun of 
the runway.
    The original issue of this directive mandated the introduction 
of non-normal procedures to the airplane flight manual (AFM) as an 
interim corrective action to address PSEU failures.
    Revision 1 of this directive amends the aircraft applicability 
and introduces a note providing terminating action, for use at 
operator discretion, if the aircraft has incorporated a PSEU with 
software version 12 in accordance with Bombardier Service Bulletin 
(SB) 100-32-12.

Actions and Compliance

    (f) Unless already done, within 14 days after the effective date 
of this AD: Revise the Limitations Section of the Bombardier 
Challenger 300 AFM, CSP 100-1, to include the information in 
Bombardier Temporary Revision TR-39, dated March 2, 2005, as 
specified in the temporary revision. This temporary revision 
introduces a procedure for ``PROX SYS FAULT (A)'' and modifies the 
``WOW FAIL (C)'' and ``GEAR SYS FAIL (C)'' procedures.

    Note 1:  This may be done by inserting a copy of Bombardier 
Temporary Revision TR-39, dated March 2, 2005, in the AFM. When this 
temporary revision has been included in general revisions of the 
AFM, the general revisions may be inserted in the AFM, provided the 
relevant information in the general revision is identical to that in 
Bombardier Temporary Revision TR-39, dated March 2, 2005.


    Note 2:  If the aircraft has incorporated a PSEU, part number 
(P/N) 30227-0401, 30227-0402, or 30227-0403, with software version 
12, installed in accordance with Bombardier Service Bulletin 100-32-
12, dated June 4, 2007, it is permissible to follow the revised AFM 
procedures included in Bombardier Temporary Revision TR-46, dated 
March 27, 2008, in lieu of using Bombardier Temporary Revision TR-
39, dated March 2, 2005, specified in paragraph (f) of this AD.

FAA AD Differences

    Note 3:  This AD differs from the MCAI and/or service 
information as follows: No differences.
