Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 series airplanes, that currently requires measuring the gap between the bellcrank and the body of the rotary variable inductive transducers (RVITs) of the aileron and elevator, performing corrective action if necessary, and torquing the bolt that attaches the bellcrank to the RVIT shaft. This action would require replacing the aileron and elevator RVIT bellcranks with new, improved bellcranks. The actions specified by the proposed AD are intended to prevent restricted movement of the aileron or elevator, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
