## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2023-21-06, which applies to certain Embraer S.A. (Embraer) Model EMB- 505 airplanes. AD 2023-21-06 requires installing structural reinforcements on certain monuments and replacing certain floor support rivets. Since the FAA issued AD 2023-21-06, the FAA has determined that certain airplanes need to be re-assigned to a different group and certain re-identified floor support part numbers need to be corrected. This proposed AD would require installing structural reinforcements on monuments and replacing fasteners on the floor support, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
