Another Icing-related AD for Caravans

The FAA last month issued AD 2006-06-06, the result of further icing accidents and incidents involving the Cessna Caravan, flight manual revisions that contain erroneous data and the outcome of recent flight tests. The directive supersedes AD 2005-07-01, issued in March last year. The FAA said that flight manual revisions issued on Dec. 5, 2005, contain incorrect maximum weight limits for 600-shp Caravans, that climb performance in clear ice is lower than the data published in the revisions, and flight tests indicate that the “aural stall warning system will not activate before a stall in some icing conditions.”
