This AD results from reports of several accidents involving the affected airplanes during operations in flight and in ground icing conditions. This AD is intended to provide a safe method to detect ice, snow, frost, or slush adhering to the upper wing (a critical surface) prior to takeoff; and to reduce drag in-flight by shedding ice on the cargo pod and landing gear fairings. Ice adhering to the upper wing surface, cargo pod, or landing gear fairings could result in a reduction in aeroplane performance with the consequences that the aeroplane cannot perform a safe takeoff or climb.Amendment 1 changed the applicability of the aeroplane listed in requirements 3 and 4, and changes the compliance period for requirement 2. These changes were made following a correction to the referenced FAA AD.Amendment 2 corrected the aircraft described in Requirement 3 following a correction to FAA AD 2006-01-11R1 being issued. The change is shown in bold type and reads:“For Cessna Model 208B with Pratt & Whitney of Canada Ltd., PT6A-114 Turbo Prop engine installed (600 SHP) or equivalent, and equipped with a cargo pod and pneumatic de-icing boots, do one of the following:”This amendment changes the applicability to exclude aircraft not certified for flight into known icing conditions.The original issue of this AD became effective on 11 May 2006.Amendment 1 of this AD became effective on 11 May 2006.Amendment 2 of this AD became effective on 27 September 2006. |\n\n![](image.001.png)\n\nDavid Alan Villiers \nDelegate of the Civil Aviation Safety Authority\n\n22 July 2010","sortOrder":0},{"sectionNumber":"AD/CESSNA 208/19 Amdt 3","sectionType":"part","heading":"AD/CESSNA 208/19 Amdt 3","content":"## AD/CESSNA 208/19 Amdt 3","sortOrder":1},{"sectionNumber":"Flight and Ground Icing Operations","sectionType":"part","heading":"Flight and Ground Icing Operations","content":"## Flight and Ground Icing Operations","sortOrder":2},{"sectionNumber":"15/2010","sectionType":"part","heading":"15/2010","content":"## 15/2010","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":6,"scope_assessment":{"changed":true,"description":"Yes.
