## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2018-19-28, which applies to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes; and AD 2014-16-16, which applies to all of those airplane models. AD 2014-16-16 requires, for certain airplanes, retorquing and replacing the pylon lower link fittings, and for all airplanes, repetitively retorquing those fittings. AD 2018-19-28 requires modifying the attaching parts of the pylon lower link fittings. Since the FAA issued AD 2014-16-16 and AD 2018-19-28, the FAA finds it necessary to change the compliance time for the modification. This proposed AD would require an inspection of certain shear pins, replacement if necessary, and revised compliance times for the modification, as specified in an Agencia Nacional de Aviacao Civil (ANAC) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
