## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and EMB-145 series airplanes, that would have required inspecting the pilot's and co-pilot's seat tracks for proper locking of the seats, and adjusting or replacing the seat tracks, if necessary. This new action revises the proposed rule by revising the applicability statement, and requiring replacement of the seat locking pin on certain SICMA-brand seats. The actions specified by this new proposed AD are intended to prevent uncommanded movement of the pilot's or co-pilot's seat, which could interfere with the operation of the airplane and consequent temporary loss of airplane control. This action is intended to address the identified unsafe condition.
