## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2020-23-13, which applies to all ATR--GIE Avions de Transport R(eacute)gional Model ATR42-200, -300, and -320 airplanes. AD 2020-23- 13 requires a one-time inspection for discrepancies of the wire bundles between the left- and right-hand angle of attack (AOA) probes and the crew alerting computer, and, depending on findings, applicable corrective actions. Since the FAA issued AD 2020-23-13, a wiring modification for the captain stick shaker has been developed, along with an update to the aircraft flight manual (AFM). This proposed AD would continue to require the actions in AD 2020-23-13. This proposed AD would also require, for certain airplanes, modifying the captain stick shaker wiring, and for all airplanes, revising the existing AFM and applicable corresponding operational procedures to incorporate procedures for the stick pusher/shaker, as specified in a European Union Aviation Safety Agency (EASA), which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
