Saab AB, Support and Services (Formerly Known as Saab AB, Saab Aeronautics) Airplanes
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).
The FAA is adopting a new airworthiness directive (AD) for certain Saab AB, Support and Services Model 340A (SAAB/SF340A) and SAAB 340B airplanes. 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. This AD requires modification of the stall warning/identification system, 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.
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.
(1) Where EASA AD 2022-0216R1 refers to November 16, 2022 (the effective date of EASA AD 2022-0216), this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2022-0216R1 does not apply to this AD.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, 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 International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: 9-AVS-AIR-730-AMOC@faa.gov. 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, 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.
