Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-550 and EMB-545 airplanes. This proposed AD was prompted by reports of cracks, delamination, and failure of the flight deck side windows during certification fatigue tests. This proposed AD would require repetitive inspections of the flight deck side windows for any cracking or delamination, corrective action if necessary, and eventual replacement of the windows, as specified in an Ag(ecirc)ncia Nacional de Avia(ccedil)(atilde)o Civil (ANAC) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
