14 CFR Part 39 

[Docket No. FAA–2023–1896; Project 

Identifier MCAI–2023–00837–T; Amendment 

39–22633; AD 2023–25–06]

Airworthiness Directives; Saab AB, 

Support and Services (Formerly 

Known as Saab AB, Saab Aeronautics) 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), 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 review of the anti-skid system that 

revealed the possibility of inadvertently 

connecting the inboard harness to the 

outboard channel (and vice versa) of the 

wheel speed transducers in the main 

landing gear (MLG) wheel axles. This 

AD requires installing color markings on 

the harnesses and the wheel axles, to 

ensure proper installation and 

connection of the anti-skid harnesses, 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 February 7, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of February 7, 2024. 

ADDRESSES: 

AD Docket: You may examine the AD 

docket at regulations.gov under Docket 

No. FAA–2023–1896; or in person at 

Docket Operations between 9 a.m. and 

5 p.m., Monday through Friday, except 

Federal holidays. The AD docket 

contains this final rule, the mandatory 

continuing airworthiness information 

(MCAI), any comments received, and 

other information. The address for 

Docket Operations is U.S. Department of

SUPPLEMENTARY INFORMATION: 

Background 

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 5, 2023 (88 FR 

69105). The NPRM was prompted by 

AD 2023–0135, dated July 10, 2023, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union (EASA AD 2023–0135) 

(also referred to as the MCAI). The 

MCAI states a system review of the antiskid system revealed the possibility of 

inadvertently connecting the inboard 

harness to the outboard channel (and 

vice versa) of the wheel speed 

transducers in the MLG wheel axles. 

This condition, if not detected and 

corrected, would lead to wrong inputs 

to the anti-skid function, whenever 

activated, with consequent reduced 

braking capability, possibly resulting in 

damage to the airplane. 

In the NPRM, the FAA proposed to 

require modification of the MLG by 

installing color markings on the 

harnesses and the wheel axles, to ensure 

proper installation and connection of 

the anti-skid harnesses, as specified in 

EASA AD 2023–0135. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1896. 

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 

This product has been approved by 

the aviation authority of another 

country and is approved for operation in 

the United States. Pursuant to the FAA’s 

bilateral agreement with this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

reviewed the relevant data and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on this 

product. 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. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2023–0135 specifies 

procedures for modifying the left- and 

right-hand MLG and connectors with 

color markings. 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 17 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 

10 work-hours × $85 per hour = $850 ........................................................................................ $1,740 $2,590 $44,030

Federal Register / Vol. 89, No. 2 / Wednesday, January 3, 2024 / Rules and Regulations 241 

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. 

List of Subjects in 14 CFR Part 39

The Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

2023–25–06 Saab AB, Support and Services 

(Formerly Known as Saab AB, Saab 

Aeronautics): Amendment 39–22633; 

Docket No. FAA–2023–1896; Project 

Identifier MCAI–2023–00837–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective February 7, 2024. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Saab AB, Support 

and Services (formerly known as Saab AB, 

Saab Aeronautics) Model SAAB 2000 

airplanes, certificated in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 32, Landing gear. 

(e) Unsafe Condition 

This AD was prompted by a review of the 

anti-skid system that revealed the possibility 

of inadvertently connecting the inboard 

harness to the outboard channel (and vice 

versa) of the wheel speed transducers in the 

main landing gear (MLG) wheel axles. The 

FAA is issuing this AD to address incorrect 

connections of the harnesses to the wheel 

speed transducers. The unsafe condition, if 

not addressed, could result in wrong inputs 

to the anti-skid function, whenever activated, 

with consequent reduced braking capability, 

possibly resulting in damage to the airplane. 

(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, EASA AD 2023–0135, 

dated July 10, 2023 (EASA AD 2023–0135). 

(h) Exceptions to EASA AD 2023–0135 

(1) Where EASA AD 2023–0135 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) Where EASA AD 2023–0135 requires a 

‘‘visual check,’’ this AD requires replacing 

those words with ‘‘visual inspection.’’ 

(3) This AD does not adopt the ‘‘Remarks’’ 

section of EASA AD 2023–0135. 

(i) Additional AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance
