Applicability*9

This AD applies to Saab AB, Support and Services (formerly known as Saab AB, Saab Aeronautics) Model 340A (SAAB/SF340A) and SAAB 340B airplanes, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2022-0216R1, dated February 1, 2023; corrected February 2, 2023 (EASA AD 2022-0216R1).

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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 2022-0216R1.

Unsafe condition

This 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. The FAA is issuing this AD to address a margin to stall warning that is lower when ice speed is ON than with ice speed OFF. The unsafe condition, if not addressed, could lead to inappropriate stall warnings during the landing phase and result in increased pilot workload during a critical phase of flight.

Affected ADs

None.
