Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Saab AB, Support and Services Model SAAB 340B airplanes. This AD was prompted by a determination that the affected airplanes must not be operated at a maximum take-off weight (MTOW) above 29,000 pounds. This AD requires amending the applicable airplane flight manual (AFM) by incorporating a temporary revision (TR) to reduce the MTOW, 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.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2023-0121, dated June 13, 2023 (EASA
AD 2023-0121) (also referred to as the MCAI), to correct an unsafe
condition for certain Saab AB, Support and Services Model SAAB 340B
airplanes. The MCAI states that the affected airplanes must not be
operated at a MTOW above 29,000 pounds. This condition, if not
corrected, could allow flight in an uncertified envelope, and therefore
could lead to a potential unsafe condition.
The FAA is issuing this AD to address the possibility of flight in
an uncertified envelope, which could result in reduced structural
capability and reduced controllability of the airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1401.
Related Service Information Under 1 CFR Part 51
EASA AD 2023-0121 specifies procedures for amending the applicable
AFM by incorporating the specified AFM TR to reduce the MTOW. 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.
FAA's Determination
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 is issuing this AD after determining that the
unsafe condition described previously is likely to exist or develop on
other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA AD
2023-0121 described previously, except for any differences identified
as exceptions in the regulatory text of this AD.
Compliance With AFM Revisions
EASA AD 2023-0121 requires operators to ``inform all flight crews''
of revisions to the AFM, and thereafter to ``operate the aeroplane
accordingly.'' However, this AD would not specifically require those
actions as those actions are already required by FAA regulations. FAA
regulations require operators furnish to pilots any changes to the AFM
(for example, 14 CFR 121.137), and to ensure the pilots are familiar
with the AFM (for example, 14 CFR 91.505). As with any other flightcrew
training requirement, training on the updated AFM content is tracked by
the operators and recorded in each pilot's training record, which is
available for the FAA to review. FAA regulations also require pilots to
follow the procedures in the existing AFM including all updates. 14 CFR
91.9 requires that any person operating a civil aircraft must comply
with the operating limitations specified in the AFM. Therefore,
including a requirement in this AD to operate the airplane according to
the revised AFM would be redundant and unnecessary.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result,
EASA AD 2023-0121 is incorporated by reference in this AD. This AD
requires compliance with EASA AD 2023-0121 in its entirety through that
incorporation, except for any differences identified as exceptions in
the regulatory text of this AD. Using common terms that are the same as
the heading of a particular section in EASA AD 2023-0121 does not mean
that operators need comply only with that section. For example, where
the AD requirement refers to ``all required actions and compliance
times,'' compliance with this AD requirement is not limited to the
section titled ``Required Action(s) and Compliance Time(s)'' in EASA AD
2023-0121. Service information required by EASA AD 2023-0121 for
compliance will be available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-
2023-1401 after this AD is published.
FAA's Justification and Determination of the Effective Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because the MTOW for the airplane was increased from 29,000 to 30,000
pounds without determining if the propeller MTOW could be increased to
30,000 pounds. Therefore, the airplanes must not be operated at a MTOW
above 29,000 pounds.
This condition, if not corrected, could result in the possibility
of flight in an uncertified envelope, which could result in reduced
structural capability and reduced controllability of the airplane. In
addition, the required AFM amendment must be done within a compliance
time of 7 days in order to address the unsafe condition. Accordingly,
notice and opportunity for prior public comment are impracticable and
contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forgo notice and
comment.
Regulatory Flexibility Act (RFA)
The requirements of the RFA do not apply when an agency finds good
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and
comment. Because the FAA has determined that it has good cause to adopt
this rule without notice and comment, RFA analysis is not required.

Costs of Compliance
The FAA estimates that this AD affects 64 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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $0 $85 $5,440
----------------------------------------------------------------------------------------------------------------
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, and
(2) Will not affect intrastate aviation in Alaska.
