SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0058, dated March 1, 2021 (EASA AD 2021– 0058) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Saab AB, Support and Services Model SAAB 340B airplanes. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Saab AB, Support and Services Model SAAB 340B airplanes. The NPRM published in the Federal Register on August 9, 2021 (86 FR PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 43451). The NPRM was prompted by report that the circuit breaker for the emergency cabin lighting tripped without fault in the system. The NPRM proposed to require replacing a certain circuit breaker with a part having a higher rating, as specified in EASA AD 2021–0058. The FAA is issuing this AD to address the low rating of the 2LN circuit breaker during maximum charging conditions. This condition, if not corrected, could lead to an insufficiently charged emergency battery, with consequent loss of cabin emergency lighting, possibly resulting in injury to occupants during an evacuation. See the MCAI for additional background information. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0058 describes procedures for replacing the 2LN circuit breaker having a rating of 5A with a new breaker having a current rating of 7.5A. This material 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 27 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\01DER1.SGM 01DER1 68106 Federal Register / Vol. 86, No. 228 / Wednesday, December 1, 2021 / Rules and Regulations ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $50 $135 $3,645 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

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.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0058, dated March 1, 2021 (EASA 
AD 2021-0058) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Saab AB, Support and Services Model SAAB 340B airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Saab AB, 
Support and Services Model SAAB 340B airplanes. The NPRM published in 
the Federal Register on August 9, 2021 (86 FR 43451). The NPRM was 
prompted by report that the circuit breaker for the emergency cabin 
lighting tripped without fault in the system. The NPRM proposed to 
require replacing a certain circuit breaker with a part having a higher 
rating, as specified in EASA AD 2021-0058.
    The FAA is issuing this AD to address the low rating of the 2LN 
circuit breaker during maximum charging conditions. This condition, if 
not corrected, could lead to an insufficiently charged emergency 
battery, with consequent loss of cabin emergency lighting, possibly 
resulting in injury to occupants during an evacuation. See the MCAI for 
additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
requires adopting this AD as proposed. Except for minor editorial 
changes, this AD is adopted as proposed in the NPRM. None of the 
changes will increase the economic burden on any operator. Accordingly, 
the FAA is issuing this AD to address the unsafe condition on these 
products.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0058 describes procedures for replacing the 2LN 
circuit breaker having a rating of 5A with a new breaker having a 
current rating of 7.5A.
    This material 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 27 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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.
