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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Saab AB, Support and Services Model 340A (SAAB/SF340A) and
SAAB 340B airplanes. This proposed AD was prompted by reports of a high
number of events related to stall warnings upon landing, following
introduction of the ice speed function within the stall warning system.
This proposed AD would require modification of the stall warning/
identification system, as specified in a European Union Aviation Safety
Agency (EASA) AD, which is proposed for incorporation by reference
(IBR). The FAA is proposing this AD to address the unsafe condition on
these products.

DATES: The FAA must receive comments on this proposed AD by August 4,
2023.

docket for this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2022-0216R1, dated February 1, 2023;
corrected February 2, 2023 (EASA AD 2022-0216R1) (also referred to as
the MCAI), to correct an unsafe condition for SAAB SF340A and SAAB 340B
airplanes, all serial numbers, except those that have SAAB modification
number 2650 (Canada Ice Speed Configuration) embodied. The MCAI states
that following the introduction of the ice speed function within the
SAAB 340 stall warning system, a high number of events have been
reported related to stall warnings upon landing. Subsequent
investigation determined that the margin to stall warning is lower when
ice speed is ON than with ice speed OFF. This condition, if not
corrected, could lead to inappropriate stall warnings during the
landing phase

and result in increased pilot workload during a critical phase of
flight.
    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-2023-1215.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0216R1 specifies procedures for modifying the stall
warning/identification system to introduce an ice speed cancel logic.
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 ADDRESSES.

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 the State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
described above. The FAA is issuing this NPRM after determining that
the unsafe condition described previously is likely to exist or develop
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified
in EASA AD 2022-0216R1 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.

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, the
FAA proposes to incorporate EASA AD 2022-0216R1 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2022-0216R1 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2022-0216R1 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 2022-
0216R1. Service information required by EASA AD 2022-0216R1 for
compliance will be available at regulations.gov under Docket No. FAA-
2023-1215 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 79 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
             Labor cost                Parts cost           Cost per product           Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 30 work-hours x $85 per hour           $7,900  Up to $10,450................  Up to $825,550.
 = $2,550.
----------------------------------------------------------------------------------------------------------------

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

    The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
