Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-19-10. Comply with the one in force.
All Model EMB-120 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all EMBRAER Model EMB-120 series airplanes. This action requires a one-time inspection of the movable backstop of the elevator pitch trim command system to ensure that it is installed correctly, and corrective action, if necessary. This action also requires installation of a guide to maintain the movable backstop in its correct position. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent a sudden change in pitch attitude caused by autopilot disconnect, which could result in reduced controllability of the airplane.
