turboprop engine installed (600 SHP) or FAA-approved engine of equivalent horsepower installed, equipped with airframe de-icing pneumatic boots, which are not currently prohibited from flight in known or forecast icing.
             Note 1:  The above supplements require the installation of a low speed awareness (LSA) system.  Cessna Service Bulletin CAB06-11 and Cessna Caravan Service Kit SK208-171, both dated 9 October 2006 provide instructions for such an installation.
                2. Remove the placards installed on the aeroplane in accordance with AD/CESSNA 208/20 Amdt 1 Requirement 2.c.
                3. Remove any temporary revisions and amendments from the AFM/POH incorporated in accordance with AD/CESSNA 208/20 Amdt 1.
             Note 2:  The aeroplane Owner/Operator holding at least a Private Pilot Licence may carry out the AFM/POH changes detailed in Requirement 1and 3 provided that they make an entry in the aircraft records showing compliance with AD/CESSNA 208/21 Requirement 1 and 3.
             Note 3:  FAA AD 2007-10-15 Amdt 39-15056 refers.
Compliance:  For Requirement 1 - Within 90 days after the effective date of this Directive.
             For Requirements 2 and 3 - Immediately after compliance with Requirement 1.
             This Amendment becomes effective on 5 July 2007.
Background:  Currently AD/CESSNA 208/20 Amdt 1 requires the incorporation of information into the applicable section of the AFM/POH together with the installation of placards.  This Directive was based on United States Federal Aviation Administration (FAA) AD 2006-06-06 as corrected on 5 April 2006.  Since AD 2006-06-06 was issued Cessna has issued new S1 AFM supplements addressing 'Known Icing Equipment' and developed a low airspeed awareness system.
             Consequently, the original issue of this Directive required the incorporation of the applicable AFM supplement revision together with the temporary retention of the requirements of AD/CESSNA 208/20 Amdt 1 until the new AFM supplement revisions are incorporated.  The Directive also required the installation of a low airspeed awareness system.  (One of the revised AFM supplement requirements being the installation of a functional low airspeed awareness system to operate the aeroplane in known icing conditions.)

   The original issue of this Directive was issued to assure that the pilot has enough information and the necessary equipment to prevent loss of control of the aeroplane while flying in icing conditions.  This Amendment continues that action.
   This Amendment is issued to clarify the applicability of the original issue following advice from the FAA.  The Amendment limits the applicability to aeroplanes equipped with the optional Cessna flight into known icing equipment package and removes the requirement to install a LSA system, noting that the LSA system must be installed when the AFM Supplement S1 is incorporated in the AFM/POH.
   AD/CESSNA 208/20 Amdt 1 will be cancelled once the compliance period of this Directive has passed.
