Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and EMB-145 Series Airplanes

Zusammenfassung

This amendment adopts a new airworthiness directive (AD) that is applicable to all EMBRAER Model EMB-135 and EMB-145 series airplanes. This action requires a revision to the Airplane Flight Manual (AFM) to prohibit in-flight operations of the autopilot coupled to flight director #2 during certain conditions; and installation of an associated warning placard. 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 failure of the autopilot to automatically disconnect from flight director #2, as intended, at a low altitude during windshear conditions. Such failure could result in reduced controllability of the airplane.
