## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Embraer S.A. Model EMB-135ER, -135KE, -135KL, and -135LR airplanes; and Model EMB-145, -145EP, -145ER, -145LR, -145MP, -145MR, and -145XR airplanes. This proposed AD was prompted by a structural assessment that indicated certain central fuselage longitudinal splices are subjected to fatigue damage on multiple sites due to loose fasteners, which may reduce the structural residual strength below the required levels. This proposed AD would require performing repetitive inspections of certain upper central fuselage longitudinal splices and reporting the inspection results, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also require performing corrective actions if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
