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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: 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.

DATES: This AD is effective July 21, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 21, 
2023.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private,

[[Page 43053]]

that you actually treat as private, and that is relevant or responsive 
to this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Shahram 
Daneshmandi, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 
410, Westbury, NY 11590; telephone 206-231-3220; email 
[email protected]. Any commentary that the FAA receives which 
is not specifically designated as CBI will be placed in the public 
docket for this rulemaking.

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 regulations.gov 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 regulations.gov 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.

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.
