Airworthiness Directives; Beech Aircraft Corporation Models 60 and A60 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to Beech Aircraft Corporation (Beech) Models 60 and A60 airplanes. This action requires incorporating flight manual supplement revisions into the Airplane Flight Manual (AFM) that would specify a minimum airspeed for operating the affected airplanes in icing conditions. Reports of several incidents and accidents on the affected airplanes related to flight in icing conditions prompted the proposed action. The actions specified by the proposed AD are intended to prevent loss of control of the airplane because of the airplane traveling too slowly in icing conditions.
