SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2020–07, dated March 17, 2020 (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Bombardier, Inc., Model BD– 700–1A10 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–2020–0843. 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–700–1A10 airplanes. The NPRM published in the Federal Register on September 17, 2020 (85 FR 58010). The NPRM was prompted by a report of smoke and signs of an overheating condition from the ELB due to excessive corrosion surrounding the internal lead acid batteries, which caused an electrical short circuit that led to the smoke and overheating condition. The NPRM proposed to require an inspection to determine the last replacement date of the ELB, and replacement if necessary. The NPRM also proposed to require the incorporation of a new maintenance task into the existing maintenance or inspection program. The FAA is issuing this AD to address smoke and an overheating condition of the ELB due to corrosion, which could cause fire onboard the airplane. See the MCAI for additional background information. Comments 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. E:\FR\FM\23FER1.SGM 23FER1 10748 Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Rules and Regulations Request To Update Bombardier Email Address Bombardier requested that the FAA revise the NPRM to update the email address for obtaining the specified service information from ‘‘thd.crj@ aero.bombardier.com’’ to ‘‘ac.yul@ aero.bombardier.com.’’ The FAA agrees with the request and has revised this final rule accordingly. Clarifications of Compliance Times The FAA has revised paragraph (g) of this AD to clarify when replacement is required. This clarification explains that replacement is required if, during the inspection required by paragraph (g) of this AD, any last replacement date or manufacturing date is found to be 4 years or older. The FAA has also revised paragraph (h)(2) of this AD to clarify that the compliance time of within 48 months is related to the applicable date specified in paragraph (h)(2)(i) or (ii) of this AD. The proposed AD inadvertently stated that the compliance time was ‘‘[w]ithin 48 months after the applicable compliance time specified in paragraph (h)(2)(i) or (ii) of this AD,’’ but paragraphs (h)(2)(i) and (ii) of this AD specify dates, not compliance times. 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 with the changes described previously and 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. The FAA also determined that this change will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 Bombardier has issued Service Bulletin 700–33–024, dated May 13, 2019. This service information describes procedures for an inspection to determine the last battery replacement date of the ELB, and replacement if necessary. Bombardier also issued the following service information. • Global Express BD–700 Supplemental Time Limits/Maintenance Checks (STLMC) Temporary Revision (TR) 05–19091701, dated September 17, 2019. • Global Express BD–700 STLMC TR 05–19091704, dated September 17, 2019. • Global Express XRS BD–700 STLMC TR 05–19091705, dated September 17, 2019. These documents describe an amendment to the aircraft maintenance schedule to include STLMC Chapter 5 task number 33–51–54–603, ‘‘Restoration of the Emergency Lighting Batteries (XL245–B Emergency Battery System),’’ and are distinct since they apply to different airplane serial numbers. 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 69 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 3 work-hours × $85 per hour = $255 .......................................................................................... $11,308 $11,563 $797,847 The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the FAA recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). 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 VerDate Sep<11>2014 21:28 Feb 22, 2021 Jkt 253001 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. (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. Regulatory Findings Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: 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 PO 00000 Frm 00046 Fmt 4700 Sfmt 4700 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; Bombardier, Inc., Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model BD-700-1A10 airplanes. This AD was 
prompted by a report of smoke and signs of an overheating condition 
from the emergency light battery (ELB) due to excessive corrosion 
surrounding the internal lead acid batteries, which caused an 
electrical short circuit that led to the smoke and overheating 
condition. This AD requires an inspection to determine the last 
replacement date of the ELB, and replacement if necessary. This AD also 
requires the incorporation of a new maintenance task into the existing 
maintenance or inspection program. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective March 30, 2021.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2020-07, dated March 
17, 2020 (also referred to as the Mandatory Continuing Airworthiness 
Information, or the MCAI), to correct an unsafe condition for certain 
Bombardier, Inc., Model BD-700-1A10 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-2020-0843.
    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-700-1A10 airplanes. The NPRM published in the Federal 
Register on September 17, 2020 (85 FR 58010). The NPRM was prompted by 
a report of smoke and signs of an overheating condition from the ELB 
due to excessive corrosion surrounding the internal lead acid 
batteries, which caused an electrical short circuit that led to the 
smoke and overheating condition. The NPRM proposed to require an 
inspection to determine the last replacement date of the ELB, and 
replacement if necessary. The NPRM also proposed to require the 
incorporation of a new maintenance task into the existing maintenance 
or inspection program. The FAA is issuing this AD to address smoke and 
an overheating condition of the ELB due to corrosion, which could cause 
fire onboard the airplane. See the MCAI for additional background 
information.

Comments

    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.

[[Page 10748]]

Request To Update Bombardier Email Address

    Bombardier requested that the FAA revise the NPRM to update the 
email address for obtaining the specified service information from 
``[email protected]'' to ``[email protected].''
    The FAA agrees with the request and has revised this final rule 
accordingly.

Clarifications of Compliance Times

    The FAA has revised paragraph (g) of this AD to clarify when 
replacement is required. This clarification explains that replacement 
is required if, during the inspection required by paragraph (g) of this 
AD, any last replacement date or manufacturing date is found to be 4 
years or older.
    The FAA has also revised paragraph (h)(2) of this AD to clarify 
that the compliance time of within 48 months is related to the 
applicable date specified in paragraph (h)(2)(i) or (ii) of this AD. 
The proposed AD inadvertently stated that the compliance time was 
``[w]ithin 48 months after the applicable compliance time specified in 
paragraph (h)(2)(i) or (ii) of this AD,'' but paragraphs (h)(2)(i) and 
(ii) of this AD specify dates, not compliance times.

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 with the changes described previously 
and 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.
    The FAA also determined that this change will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 700-33-024, dated May 13, 
2019. This service information describes procedures for an inspection 
to determine the last battery replacement date of the ELB, and 
replacement if necessary.
    Bombardier also issued the following service information.
     Global Express BD-700 Supplemental Time Limits/Maintenance 
Checks (STLMC) Temporary Revision (TR) 05-19091701, dated September 17, 
2019.
     Global Express BD-700 STLMC TR 05-19091704, dated 
September 17, 2019.
     Global Express XRS BD-700 STLMC TR 05-19091705, dated 
September 17, 2019.
    These documents describe an amendment to the aircraft maintenance 
schedule to include STLMC Chapter 5 task number 33-51-54-603, 
``Restoration of the Emergency Lighting Batteries (XL245-B Emergency 
Battery System),'' and are distinct since they apply to different 
airplane serial numbers.
    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 69 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
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255...........................         $11,308          $11,563         $797,847
----------------------------------------------------------------------------------------------------------------

    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the FAA recognizes that this number may vary from operator to 
operator. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), the FAA has determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, the FAA estimates the total cost per operator to be $7,650 
(90 work-hours x $85 per work-hour).

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

    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.
