Airworthiness Directives; Embraer S.A. Airplanes

FAA / Federal Register · 2019-20829

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This proposed AD was prompted by reports of structural cracks in the wing lower skin stringers on both half wings. This proposed AD would require repetitive inspections of the lower skin stringers on both half wings for cracking or fuel leakage, and applicable related investigative and corrective actions, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) Brazilian AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
