## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Yabora Industria Aeronautica S.A. Model ERJ 170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 ECJ, - 100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This proposed AD was prompted by reports of installation of inverted poles of the horizontal stabilizer pitch trim switches on the control yokes, which causes opposite commands for the horizontal stabilizer. This proposed AD would require installing supports for the horizontal stabilizer control yoke pitch trim switches and re-identifying the control yokes, as specified in two Agencia Nacional de Aviacao Civil (ANAC) ADs, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
