SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2019–33R1, dated January 23, 2020 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model BD–700–1A10 and BD–700– 1A11 airplanes. You may examine the MCAI on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 0100. This AD was prompted by reports that MLG trailing arm assemblies were found with compromised paint finish and corrosion on the axle bore inner diameters due to improper removal of contaminants during manufacturing. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 The FAA is issuing this AD to address possible corrosion on the inner diameter of the MLG trailing arm assembly bore, which, if not detected and corrected, could lead to MLG collapse. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information. • Bombardier Service Bulletin 700– 1A11–32–026, Revision 01, dated November 27, 2019. • Bombardier Service Bulletin 700– 32–039, Revision 01, dated November 27, 2019. • Bombardier Service Bulletin 700– 32–5016, Revision 01, dated November 27, 2019. • Bombardier Service Bulletin 700– 32–6016, Revision 01, dated November 27, 2019. This service information describes procedures for a one-time inspection to determine if an affected MLG trailing arm assembly is installed, repetitive detailed inspections of the inner diameter of the affected MLG trailing arm assembly axle bore for surface finish discrepancies, corrective actions if necessary, and eventual replacement of primer and paint and application of corrosion preventive compound on the inner diameter of all affected MLG trailing arm assembly axle bores, which terminates the repetitive inspections. Surface finish discrepancies include corrosion, paint that is bubbling, loose, flaking, cracked, damaged or missing, or primer or metallic-ceramic coating that is visible. Corrective actions include repair or replacement of the MLG trailing arm assembly. These documents are distinct since they apply to different airplane models and configurations. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA’s Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to a bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI and service information referenced above. The FAA is issuing this AD because the agency 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. E:\FR\FM\26FER1.SGM 26FER1 Federal Register / Vol. 85, No. 38 / Wednesday, February 26, 2020 / Rules and Regulations the unsafe condition and is based on risk analysis requirements, including reports of compromised paint finish and corrosion on the axle bore inner diameters. To support this risk analysis and to provide for coordinated implementation of TCCA’s regulations in paragraph (i) of this AD, the FAA is using the same compliance dates in this AD. Requirements of This AD This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this AD and the MCAI or Service Information.’’ This AD also requires sending the inspection results to Bombardier. Differences Between This AD and the MCAI or Service Information The MCAI specifies to accomplish the one-time inspection to determine if an affected MLG trailing arm assembly is installed within 3 months from November 27, 2019 (the release date of Revision 01 of the applicable service information specified in the Related Service Information under 1 CFR part 51 paragraph of this AD). The FAA has determined that a compliance time of within 30 days after the effective date of this AD is acceptable to address the unsafe condition. Explanation of Compliance Time Most ADs adopt a compliance time relative to the AD’s effective date. In this case, however, the FAA is using a fixed compliance date in this AD. The MCAI requires operators to accomplish a detailed inspection of the surface finish of affected MLG trailing arm assemblies at a specified time (which varies according to serial number, with the earliest date being 5/12/2020). That compliance time is necessary to address FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the affected trailing arm assemblies have the potential for improper adhesion between the anticorrosion layers, which could lead to corrosion on the inner diameter of the MLG trailing arm assembly axle bore and possibly lead to MLG collapse. Therefore, the FAA finds good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reasons stated above, the FAA finds that good cause exists for making this amendment effective in less than 30 days. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule 10975 without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and the FAA did not precede it by notice and opportunity for public comment. The FAA invites 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–2020–0100; Product Identifier 2020–NM–016–AD’’ at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this AD. The FAA will consider all comments received by the closing date and may amend this AD based on those comments. The FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact received about this AD. Costs of Compliance The FAA estimates that this AD affects 49 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Up to 33 work-hours × $85 per hour = Up to $2,805. Up to $200,000 ............................. Up to $202,805 ............................. The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the Cost on U.S. operators Up to $9,937,445. number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS * Labor cost Parts cost Cost per product Up to 20 work-hours × $85 per hour = Up to $1,700 ............................. Up to $200,000 .............................. Up to $201,700. khammond on DSKJM1Z7X2PROD with RULES * Table does not include estimated costs for reporting. We estimate that it takes about 1 work-hour per product to comply with the on-condition reporting requirement in this AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of reporting the inspection results on U.S. operators to be $85 per product. VerDate Sep<11>2014 16:11 Feb 25, 2020 Jkt 250001 According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate.

Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177–1524. khammond on DSKJM1Z7X2PROD with RULES 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. The FAA is 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. VerDate Sep<11>2014 16:11 Feb 25, 2020 Jkt 250001 Regulatory Findings The FAA has 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, and (2) Will not affect intrastate aviation in Alaska.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. 
This AD was prompted by reports that main landing gear (MLG) trailing 
arm assemblies were found with compromised paint finish and corrosion 
on the axle bore inner diameters due to improper removal of 
contaminants during manufacturing. This AD requires a one-time 
inspection to determine if an affected MLG trailing arm assembly is 
installed, repetitive detailed inspections of the inner diameter of the 
affected MLG trailing arm assembly axle bore for surface finish 
discrepancies, corrective actions if necessary, and eventual 
replacement of primer and paint and application of corrosion preventive 
compound on the inner diameter of all affected MLG trailing arm 
assembly axle bores, which terminates the repetitive inspections. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-33R1, dated 
January 23, 2020 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-
1A11 airplanes. You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0100.
    This AD was prompted by reports that MLG trailing arm assemblies 
were found with compromised paint finish and corrosion on the axle bore 
inner diameters due to improper removal of contaminants during 
manufacturing. The FAA is issuing this AD to address possible corrosion 
on the inner diameter of the MLG trailing arm assembly bore, which, if 
not detected and corrected, could lead to MLG collapse. See the MCAI 
for additional background information.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information.
     Bombardier Service Bulletin 700-1A11-32-026, Revision 01, 
dated November 27, 2019.
     Bombardier Service Bulletin 700-32-039, Revision 01, dated 
November 27, 2019.
     Bombardier Service Bulletin 700-32-5016, Revision 01, 
dated November 27, 2019.
     Bombardier Service Bulletin 700-32-6016, Revision 01, 
dated November 27, 2019.
    This service information describes procedures for a one-time 
inspection to determine if an affected MLG trailing arm assembly is 
installed, repetitive detailed inspections of the inner diameter of the 
affected MLG trailing arm assembly axle bore for surface finish 
discrepancies, corrective actions if necessary, and eventual 
replacement of primer and paint and application of corrosion preventive 
compound on the inner diameter of all affected MLG trailing arm 
assembly axle bores, which terminates the repetitive inspections. 
Surface finish discrepancies include corrosion, paint that is bubbling, 
loose, flaking, cracked, damaged or missing, or primer or metallic-
ceramic coating that is visible. Corrective actions include repair or 
replacement of the MLG trailing arm assembly. These documents are 
distinct since they apply to different airplane models and 
configurations. This service information is reasonably available 
because the interested parties have access to it through their normal 
course of business or by the means identified in the ADDRESSES section.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to a bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI and 
service information referenced above. The FAA is issuing this AD 
because the agency 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.

[[Page 10975]]

Requirements of This AD

    This AD requires accomplishing the actions specified in the service 
information described previously, except as discussed under 
``Differences Between this AD and the MCAI or Service Information.'' 
This AD also requires sending the inspection results to Bombardier.

Differences Between This AD and the MCAI or Service Information

    The MCAI specifies to accomplish the one-time inspection to 
determine if an affected MLG trailing arm assembly is installed within 
3 months from November 27, 2019 (the release date of Revision 01 of the 
applicable service information specified in the Related Service 
Information under 1 CFR part 51 paragraph of this AD). The FAA has 
determined that a compliance time of within 30 days after the effective 
date of this AD is acceptable to address the unsafe condition.

Explanation of Compliance Time

    Most ADs adopt a compliance time relative to the AD's effective 
date. In this case, however, the FAA is using a fixed compliance date 
in this AD. The MCAI requires operators to accomplish a detailed 
inspection of the surface finish of affected MLG trailing arm 
assemblies at a specified time (which varies according to serial 
number, with the earliest date being 5/12/2020). That compliance time 
is necessary to address the unsafe condition and is based on risk 
analysis requirements, including reports of compromised paint finish 
and corrosion on the axle bore inner diameters. To support this risk 
analysis and to provide for coordinated implementation of TCCA's 
regulations in paragraph (i) of this AD, the FAA is using the same 
compliance dates in this AD.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because the affected trailing arm assemblies have the potential for 
improper adhesion between the anti-corrosion layers, which could lead 
to corrosion on the inner diameter of the MLG trailing arm assembly 
axle bore and possibly lead to MLG collapse. Therefore, the FAA finds 
good cause that notice and opportunity for prior public comment are 
impracticable. In addition, for the reasons stated above, the FAA finds 
that good cause exists for making this amendment effective in less than 
30 days.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not precede it by notice and opportunity for 
public comment. The FAA invites 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-2020-0100; 
Product Identifier 2020-NM-016-AD'' at the beginning of your comments. 
The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. The FAA will 
consider all comments received by the closing date and may amend this 
AD based on those comments.
    The FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide. 
The FAA will also post a report summarizing each substantive verbal 
contact received about this AD.

Costs of Compliance

    The FAA estimates that this AD affects 49 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                      Parts cost            Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 33 work-hours x $85 per hour =   Up to $200,000.........  Up to $202,805.........  Up to $9,937,445.
 Up to $2,805.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                Estimated Costs of On-Condition Actions *
------------------------------------------------------------------------
           Labor cost                 Parts cost       Cost per product
------------------------------------------------------------------------
Up to 20 work-hours x $85 per     Up to $200,000....  Up to $201,700.
 hour = Up to $1,700.
------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    We estimate that it takes about 1 work-hour per product to comply 
with the on-condition reporting requirement in this AD. The average 
labor rate is $85 per hour. Based on these figures, we estimate the 
cost of reporting the inspection results on U.S. operators to be $85 
per product.
    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to 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

[[Page 10976]]

OMB control number. The control number for the collection of 
information required by this AD is 2120-0056. The paperwork cost 
associated with this AD has been detailed in the Costs of Compliance 
section of this document and includes time for reviewing instructions, 
as well as completing and reviewing the collection of information. 
Therefore, all reporting associated with this AD is mandatory. Comments 
concerning the accuracy of this burden and suggestions for reducing the 
burden should be directed to Information Collection Clearance Officer, 
Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 
76177-1524.

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.
    The FAA is 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

    The FAA has 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, and
    (2) Will not affect intrastate aviation in Alaska.
