Airworthiness Directives; Raytheon Aircraft Company Model 390 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Model 390 airplanes. This AD requires you to insert a temporary change into the FAA-approved Airplane Flight Manual (AFM) that adds a limitation for prohibiting flight into icing conditions and adds procedures for when an icing condition occurs. This AD is the result of reports of a manufacturing problem with the wing leading edge anti-ice system. The actions specified by this AD are intended to minimize the potential hazards associated with operating these airplanes in icing conditions by providing procedures and limitations associated with such conditions.
