## Summary

We propose to adopt a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 170 airplanes; and all 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 cracks in certain engine low-stage bleed check valves. This proposed AD would require replacing the air management system (AMS) controller operation program of the AMS controller processor boards, and replacement of the current low-stage bleed check valve and associated seals. We are proposing this AD to prevent failure of the low-stage bleed check valve, which could result in dual engine in-flight shutdown.
