ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-17-02, which applied to all ATR-GIE Avions de Transport Régional Model ATR42-200, -300, and -320 airplanes. AD 2021-17-02 required 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. AD 2021-17-02 also required, for certain airplanes, modifying the captain stick shaker wiring, and for all airplanes, revising the existing aircraft flight manual (AFM) and applicable corresponding operational procedures to incorporate procedures for the stick pusher/shaker. Since the FAA issued AD 2021-17-02, additional modification of the affected wiring for certain airplanes was developed. This AD retains all of the requirements of AD 2021-17-02 and requires installing a new AOA power supply unit and removing the AFM amendment; 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. DATES: This AD is effective October 23, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 23, 2024.
