Airworthiness Directives; Cessna Aircraft Company Models 208 and 208B Airplanes

The FAA is adopting a new airworthiness directive (AD) to supersede AD 2006-06-06, which applies to certain Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. AD 2006-06-06 currently requires you to incorporate information into the applicable section of the Airplane Flight Manual (AFM) and Pilot's Operating Handbook (POH) and requires you to install placards. Since we issued AD 2006-06-06, Cessna issued new S1 Known Icing Equipment AFM supplements and developed a low airspeed awareness system. Consequently, this AD requires you to incorporate the applicable AFM supplement revision and temporarily retain the requirements of AD 2006-06-06 until the above revisions are incorporated. One of the AFM requirements is the installation of a functional low airspeed awareness system to operate the airplane in known icing conditions. We are issuing this AD to assure that the pilot has enough information and the necessary equipment to prevent loss of control of the airplane while in-flight during icing conditions.
