Abstract
The FAA is superseding Airworthiness Directive (AD) 2023-22- 11, which applied to certain Embraer S.A. (Embraer) Model EMB-505 airplanes. AD 2023-22-11 required repetitively replacing the clutch retaining bolt and washer of the aileron autopilot servo mount. Since the FAA issued AD 2023-22-11, the FAA has determined that the applicability should include certain Model EMB-505 airplanes and, for certain airplanes, an additional requirement is necessary for the initial replacement of the retaining bolt and washer. This AD incorporates these additional airplanes into the applicability, adds the additional requirement, and also provides an optional terminating action for the repetitive retaining bolt and washer replacement. The FAA is issuing this AD to address the unsafe condition on these products.
