## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2020-12-08, which applies to all Embraer S.A. Model EMB-505 airplanes. AD 2020-12-08 requires inspections of the mass-balance weights of the elevators, ailerons, and rudder (flight control surfaces) and their attachment parts, and corrective actions if necessary, and revising the airworthiness limitation section of the maintenance manual or instructions for continued airworthiness to incorporate new airworthiness limitations. Since AD 2020-12-08 was issued, the FAA has determined that new applicable airplane serial numbers and new criteria for the replacement of affected parts must be required in order to address the unsafe condition. This proposed AD would retain the actions required by AD 2020-12-08 and would require, for certain airplanes, cleaning and weighing certain mass-balances and installation or replacement, as applicable; and for certain other mass-balances for certain airplanes, replacement of those mass-balances. The FAA is proposing this AD to address the unsafe condition on these products.
