14 CFR Part 39

Airworthiness Directives; Saab AB, Support and Services (Formerly 
Known as Saab AB, Saab Aeronautics) Airplanes

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

ACTION: Final rule.

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

SUMMARY: 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 2020-0137, dated June 18, 2020 (EASA 
AD 2020-0137) (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.

[[Page 10448]]

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.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0137 describes procedures for a one-time inspection 
for correct installation of the outboard and inboard left-hand and 
right-hand MLG anti-skid system harnesses and corrective actions if 
necessary. Corrective actions include trouble-shooting 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. 
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 11 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
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340...........................              $0             $340           $3,740
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that would enable providing 
cost estimates for the on-condition actions specified in 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.
