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

Resumo

This amendment adopts a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-145 series airplanes. This action requires revising the Airplane Flight Manual (AFM) for operation in the rain, and modifying the anemometric static ports. This action also provides for optional terminating action for the requirements of this AD. 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 limit or prohibit the use of the autopilot and flight director during the descent and approach to land in the rain, and to prevent fluctuations and erratic indications in the vertical speed, airspeed, and altitude readings in the cockpit during the descent and approach to land in the rain; such conditions could result in reduced controllability of the airplane during the descent and approach to land in the rain.
