Federal Register / Vol. 86, No. 33 / Monday, February 22, 2021 / Rules and Regulations
Comments The FAA gave the public the opportunity to participate in developing this final rule. 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 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.

Corrective actions include troubleshooting and verification of the
installation of inboard and outboard anti-skid harnesses on the left-hand and right-hand MLG; and removal, inspection, and repair of any incorrectly installed inboard and outboard anti-skid harnesses.

Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs 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 Agencys 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.

20210202 Saab AB, Support and Services Formerly Known as Saab AB, Saab Aeronautics: Amendment 3921385;
Docket No. FAA20200855; Project Identifier MCAI202000909T.

This AD applies to all Saab AB, Support and Services Model SAAB 2000 airplanes, certificated in any category.
d Subject Air Transport Association ATA of America Code 32, Landing gear.
This AD was prompted by a report of inadvertently reversed connections of the outboard and inboard channel harnesses of the wheel speed transducers in the main landing gear MLG wheel axles. The FAA is issuing this AD to address inadvertently reversed connections of the outboard and inboard channel harnesses of the wheel speed transducers in the MLG wheel axles, which could lead to wrong inputs to the antiskid function, whenever activated, with consequent reduced braking capability, and possibly result in damage to the airplane and loss of control during landing.
f Compliance Comply with this AD within the compliance times specified, unless already done.
g Requirements Except as specified in paragraph h of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency EASA AD 20200137, dated June 18, 2020 EASA AD 20200137.
