Canada’s Transportation Safety Board has made recommendations in line with the growing concern from the FAA and NTSB about the safety of Cessna 208 Caravans in icing conditions.
Further icing accidents and incidents involving the Cessna Caravan, flight manual revisions that contain erroneous data and recent flight tests prompted the FAA last week to issue AD 2006-06-06. The new directive supercedes AD 2005-07-01 issued last March.
A recent letter from the FAA’s Eastern Region regional counsel has generated concern that the agency has abruptly changed its icing policy. Regional counsel Loretta Alkalay’s letter was in response to a request by flight instructor Robert Miller for a definition of known ice. Alkalay wrote, “Known icing conditions exist when visible moisture or high relative humidity combines with temperatures near or below freezing.
Canada’s Transportation Safety Board (TSB) released the final report on the fatal icing-related crash of a Cessna 208 Caravan on Oct. 6, 2005 in Winnipeg, Canada. The Caravan was about 3 percent overweight and 200 pounds over mtow for operating in icing conditions. Moderate icing conditions were forecast in the Winnipeg area.

Investigators have determined that a Cessna 208B Caravan that crashed near Pelee Island, Ontario, on Jan. 17, 2004, exceeded the maximum allowable takeoff weight by at least 15 percent, in addition to being contaminated with ice. All 10 people on board were killed in the accident.
Cessna Aircraft has joined forces with the FAA and the Regional Air Cargo Carriers Association (RACCA) for a Cessna Caravan “educational and awareness campaign,” according to a spokesman for the OEM. The new coalition “will pool resources to enhance existing operational procedures in harsh environments, including operation in icing conditions,” proclaimed RACCA president Stan Bernstein, whose members fly the overwhelming majority of Caravans.
The NTSB yesterday asked the FAA to attend immediately to what it deemed deficiencies in the cold-weather procedures of Saab 340 pilots and the airplanes’ performance in icing conditions. The recommendations came after a review of several icing episodes in Australia and the January 2 incident in which icing forced an American Eagle Saab 340BPlus into an uncontrolled descent for 5,000 feet over Southern California.
It's going to be a photo finish between the Eclipse 500 and Cessna Citation Mustang in the race for full FAA type certification (TC). Yesterday, Cessna completed the 150-hour function and reliability testing, the last major hurdle before TC.
Raytheon Aircraft has provided operators of the Beechjet/Hawker 400XP with revised airplane flight manual (AFM) pages on the use of engine anti-icing procedures intended to prevent further flameouts on the P&WC JT15D-powered twinjet. The revisions, based on Raytheon Aircraft Safety Communiqué No.
