SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF– 2020–12, dated April 17, 2020 (TCCA AD CF–2020–12) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Bombardier, Inc., Model BD–100–1A10 airplanes. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 0859. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model BD–100–1A10 airplanes. The NPRM published in the Federal Register on October 1, 2020 (85 FR 61881). The NPRM was prompted by reports of failure of a certain FIREX control unit. The NPRM proposed to require replacing FIREX control units having a certain part number. The FAA is issuing this AD to address the failure of a FIREX control unit, which could result in the loss of the ability to detect a fire. See the MCAI for additional background information. Comment The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAA’s response to that comment. Request To Allow Records Review NetJets requested that paragraph (i) of the proposed AD be revised to allow operators to review airplane maintenance records to determine the part number of the FIREX control unit installed on an airplane. The commenter stated that for the airplane having serial number (S/N) 20662 the logbook delivery document specifies that the –3 FIREX control unit is installed. The commenter explained that there is not a signoff sheet for Bombardier Service Bulletin 350–26–001, but that the serialized parts list clearly indicates that the –3 FIREX control unit is installed. The FAA disagrees with the commenter’s request because this AD does not mandate the method an operator must use to determine what FIREX control unit part number is installed on an airplane. As specified in paragraph (c) of this AD, this AD is only 11109 applicable to Bombardier, Inc., Model BD–100–1A10 airplanes fitted with FIREX control unit part number (P/N) 474112–2. If an operator is able to confirm that FIREX control unit P/N 474112–3 is installed on an airplane the requirements of this AD are not applicable to that airplane. This AD requires operators to remove FIREX P/ N 474112–2 and install P/N 474112–3. The FAA has not changed this AD in regard to this issue. Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Bombardier has issued Service Bulletin 100–26–01, Revision 01, dated December 5, 2019; and Service Bulletin 350–26–001, Revision 01, dated December 5, 2019. This service information describes procedures for replacing FIREX control units having P/ N 474112–2 with units having P/N 474112–3. These documents are distinct since they apply to different airplane 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. Costs of Compliance The FAA estimates that this AD affects 223 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: khammond on DSKJM1Z7X2PROD with RULES ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $6,389 $6,474 $1,443,702 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 operators. The FAA does not control warranty coverage for affected operators. VerDate Sep<11>2014 16:14 Feb 23, 2021 Jkt 253001 As a result, the FAA has included all known costs in the cost estimate. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 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 E:\FR\FM\24FER1.SGM 24FER1 11110 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Rules and Regulations 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 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) Will not affect intrastate aviation in Alaska, 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.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2020-12, dated April 17, 
2020 (TCCA AD CF-2020-12) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Bombardier, Inc., Model BD-100-1A10 airplanes. You may 
examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0859.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Bombardier, 
Inc., Model BD-100-1A10 airplanes. The NPRM published in the Federal 
Register on October 1, 2020 (85 FR 61881). The NPRM was prompted by 
reports of failure of a certain FIREX control unit. The NPRM proposed 
to require replacing FIREX control units having a certain part number. 
The FAA is issuing this AD to address the failure of a FIREX control 
unit, which could result in the loss of the ability to detect a fire. 
See the MCAI for additional background information.

Comment

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comment received 
on the NPRM and the FAA's response to that comment.

Request To Allow Records Review

    NetJets requested that paragraph (i) of the proposed AD be revised 
to allow operators to review airplane maintenance records to determine 
the part number of the FIREX control unit installed on an airplane. The 
commenter stated that for the airplane having serial number (S/N) 20662 
the logbook delivery document specifies that the -3 FIREX control unit 
is installed. The commenter explained that there is not a signoff sheet 
for Bombardier Service Bulletin 350-26-001, but that the serialized 
parts list clearly indicates that the -3 FIREX control unit is 
installed.
    The FAA disagrees with the commenter's request because this AD does 
not mandate the method an operator must use to determine what FIREX 
control unit part number is installed on an airplane. As specified in 
paragraph (c) of this AD, this AD is only applicable to Bombardier, 
Inc., Model BD-100-1A10 airplanes fitted with FIREX control unit part 
number (P/N) 474112-2. If an operator is able to confirm that FIREX 
control unit P/N 474112-3 is installed on an airplane the requirements 
of this AD are not applicable to that airplane. This AD requires 
operators to remove FIREX P/N 474112-2 and install P/N 474112-3. The 
FAA has not changed this AD in regard to this issue.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 100-26-01, Revision 01, 
dated December 5, 2019; and Service Bulletin 350-26-001, Revision 01, 
dated December 5, 2019. This service information describes procedures 
for replacing FIREX control units having P/N 474112-2 with units having 
P/N 474112-3. These documents are distinct since they apply to 
different airplane 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.

Costs of Compliance

    The FAA estimates that this AD affects 223 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................          $6,389           $6,474       $1,443,702
----------------------------------------------------------------------------------------------------------------

    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 operators. The FAA does not control warranty coverage for 
affected operators. As a result, the FAA has included all known costs 
in the cost estimate.

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

[[Page 11110]]

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

    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) Will not affect intrastate aviation in Alaska, 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.
