Federal Register / Vol. 86, No. 33 / Monday, February 22, 2021 / Rules and Regulations Manager, Seattle ACO Branch, FAA, to make those findings. To be approved, the repair method, modification deviation, or alteration deviation must meet the certification basis of the airplane, and the approval must specifically refer to this AD.
4 For service information that contains steps that are labeled as Required for Compliance RC, the provisions of paragraphs k4i and ii of this AD apply.
i The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. If a step or substep is labeled RC Exempt, then the RC

Airworthiness Directives; Saab AB, Support and Services Formerly Known as Saab AB, Saab Aeronautics Airplanes Federal Aviation Administration FAA, Department of Transportation DOT.
ACTION: Final rule.
AGENCY:

The FAA is adopting a new airworthiness directive AD for all Saab AB, Support and Services Model SAAB
2000 airplanes. 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. This AD requires an inspection for correct installation of the MLG anti-skid system harnesses and corrective actions if necessary, as specified in a European Union Aviation Safety Agency EASA AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective March 29, 2021.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD
as of March 29, 2021.

SUPPLEMENTARY INFORMATION:
Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD
20200137, dated June 18, 2020 EASA
AD 20200137 referred to after this as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for all Saab AB, Support and Services Model SAAB 2000 airplanes.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to all Saab AB, Support and Services Model SAAB 2000 airplanes.
The NPRM published in the Federal Register on October 1, 2020 85 FR
61877. The NPRM was prompted by a report of inadvertently reversed connections of the outboard and inboard channel harnesses of the wheel speed transducers in the MLG wheel axles.
The NPRM proposed to require an inspection for correct installation of the MLG anti-skid system harnesses and corrective actions if necessary, as specified in an EASA AD.
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 anti-skid function, whenever activated, with consequent reduced braking capability, and possibly result in damage to the airplane and loss of control during landing. See the MCAI
for additional background information.
