EASA AD 2022-0216R1
[Correction] Flight Controls — Stall Warning / Identification System — Modification
Summary
EASA Airworthiness Directive 2022-0216R1 is a regulatory update addressing the stall warning and identification system modification for SAAB SF340A and SAAB 340B aeroplanes, excluding those with SAAB modification 2650. The directive mandates changes to the stall warning system to incorporate an ice speed cancel logic to prevent inappropriate stall warnings during landing. This AD applies to all serial numbers except those specifically exempted.
What Changed
This revision of EASA AD 2022-0216 includes references to two additional SAAB Service Bulletins (SB 340-27-132 and SB 340-27-134) to cover aircraft serial numbers that could not be modified using the original SB 340-27-131. The effective date of Revision 1 was corrected and the scope of the modification instructions was expanded to ensure all affected aircraft can comply.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent false stall warnings caused by the ice speed function in the stall warning system, which can increase pilot workload and potentially compromise safety during landing. Compliance ensures continued airworthiness and regulatory conformity under EU aviation safety regulations. It also clarifies acceptable methods of compliance and provides contact points for technical support.
What To Do
Operators of SAAB SF340A and SAAB 340B aeroplanes, except those with modification 2650, must modify the stall warning/identification system within 24 months after 16 November 2022. The modification must follow the instructions in the applicable SAAB Service Bulletins 340-27-131, 340-27-132, or 340-27-134. Alternative methods of compliance may be approved by EASA upon request and substantiation.
