## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-135BJ airplanes. This proposed AD was prompted by reports of missing sealant on the rivets installed in the interface between rib 3 and the wing skin. This proposed AD would require applying sealant on the rivets installed in the interface between rib 3 and wing skin, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
