Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. Discussion 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 indicating that the left-hand main landing gear (MLG) collapsed after touchdown, causing severe damage to the airplane. This AD requires modifying the MLG hydraulic transfer valve, 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 July 29, 2021. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 29, 2021. The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0223, dated October 14, 2020 (EASA AD 2020–0223) (also referred to 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 February 24, 2021 (86 FR 11184). The NPRM was prompted by a report indicating that the left-hand MLG collapsed after touchdown, causing severe damage to the airplane.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0223, dated October 14, 2020 
(EASA AD 2020-0223) (also referred to 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 February 24, 2021 (86 FR 11184). The NPRM was 
prompted by a report indicating that the left-hand MLG collapsed after 
touchdown, causing severe damage to the airplane. The

[[Page 33100]]

NPRM proposed to require modifying the MLG hydraulic transfer valve, as 
specified in EASA AD 2020-0223.
    The FAA is issuing this AD to address abnormal behavior of the MLG 
hydraulic transfer valve due to a restriction in hydraulic flow, which 
could cause the MLG hydraulic transfer valve to not function properly 
and fail to retract, extend, or lock the MLG, and possibly result in 
MLG collapse following landing and consequent damage to the airplane 
and injury to occupants. See the MCAI for additional background 
information.

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 2020-0223 describes procedures for modifying the MLG 
hydraulic transfer valve. This modification includes installing a new 
relay, relocation of wiring, and installation of new wiring, to ensure 
that, when the emergency extension handle is used, the transfer valve 
solenoid is energized to force the transfer valve to the ``gear down'' 
position. 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 8 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

    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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of 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

0
1. The authority citation for part 39 continues to read as follows:

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


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2021-09-11 Saab AB, Support and Services (Formerly Known as Saab AB, 
Saab Aeronautics): Amendment 39-21525; Docket No. FAA-2021-0023; 
Project Identifier MCAI-2020-01407-T.

(a) Effective Date

    This airworthiness directive (AD) is effective July 29, 2021.

(b) Affected ADs

    None.

(c) Applicability

    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.

(e) Reason

    This AD was prompted by a report indicating that the left-hand 
main landing gear (MLG) collapsed after touchdown, causing severe 
damage to the airplane. The FAA is issuing this AD to address 
abnormal behavior of the MLG hydraulic transfer valve due to a 
restriction in hydraulic flow, which could cause the MLG hydraulic 
transfer valve to not function properly and fail to retract, extend, 
or lock the MLG, and possibly result in MLG collapse following 
landing and consequent damage to the airplane and injury to 
occupants.

(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 
2020-0223, dated October 14, 2020 (EASA AD 2020-0223).

(h) Exceptions to EASA AD 2020-0223

    (1) Where EASA AD 2020-0223 refers to its effective date, this 
AD requires using the effective date of this AD.

[[Page 33101]]

    (2) The ``Remarks'' section of EASA AD 2020-0223 does not apply 
to this AD.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, International Validation Branch, FAA, has 
the authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or responsible Flight 
Standards Office, as appropriate. If sending information directly to 
the Large Aircraft Section, International Validation Branch, send it 
to the attention of the person identified in paragraph (j) of this 
AD. Information may be emailed to: [email protected]. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
responsible Flight Standards Office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, Large Aircraft 
Section, International Validation Branch, FAA; or EASA; or Saab AB, 
Support and Services' EASA Design Organization Approval (DOA). If 
approved by the DOA, the approval must include the DOA-authorized 
signature.
    (3) Required for Compliance (RC): Except as required by 
paragraph (i)(2) of this AD, if any service information contains 
procedures or tests that are identified as RC, those procedures and 
tests must be done to comply with this AD; any procedures or tests 
that are not identified as RC are recommended. Those procedures and 
tests that are not identified as RC may be deviated from using 
accepted methods in accordance with the operator's maintenance or 
inspection program without obtaining approval of an AMOC, provided 
the procedures and tests identified as RC can be done and the 
airplane can be put back in an airworthy condition. Any 
substitutions or changes to procedures or tests identified as RC 
require approval of an AMOC.
