Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Beech Aircraft Corporation (Beech) Models 60 and A60 airplanes. The proposed action would require 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 slow in icing conditions.
