4 airworthiness directives and regulations affecting SAAB SF340A.
EASA AD 2024-0042
EASA Airworthiness Directive 2024-0042 is issued for all SAAB SF340A and 340B aeroplanes. It mandates compliance with the updated Airworthiness Limitation Manual (ALM) Revision 2, which includes new and more restrictive maintenance tasks and life limits. This directive ensures continued airworthiness by updating maintenance requirements for these aircraft models.
EASA AD 2022-0216R1
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.
EASA AD 2021-0273
EASA Airworthiness Directive 2021-0273 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting SAAB SF340A and SAAB 340B aeroplanes equipped with specific Main Landing Gear torque arm centre pins. The directive addresses the replacement of torque arm centre pins with part number AIR134762 from certain batches that may lack required stress relief and de-embrittlement treatments. This AD ensures continued safe operation by mandating the replacement of these pins to prevent potential landing gear failure.
EASA SIB 2013-14R1
EASA Safety Information Bulletin 2013-14R1 addresses the aileron bell crank bearing failure issue on SAAB Model SF340A and 340B aeroplanes. It discusses the introduction of greasable bearings and improved lithium grease to mitigate corrosion caused by exposure to de-icing fluids. The bulletin clarifies that the bearing corrosion is detectable by flight crews but does not pose a direct safety risk requiring mandatory maintenance actions.
