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.
Cessna said the FAA cleared the Citation Mustang for flight into known icing two months after the new entry-level jet received FAA type certification on September 8. “While approval for flight into icing is not required for certification of the airplane, we wanted to have this in place prior to delivering our first Mustang and in advance of this year’s major icing season,” said Cessna chairman, president and CEO Jack Pelton.
Cessna 425 Conquest I, Belgrade, Mont., Nov. 29, 2005–The NTSB blamed the accident on the pilot’s failure to maintain airspeed, which resulted in an inadvertent stall. Factors were dark night conditions, clouds, icing conditions, low visibility and snow. The pilot was killed and the aircraft was destroyed when it crashed 2.8 nm northeast of Gallatin Field Airport (BZN).

The FAA issued a new Safety Alert for Operators (SAFO 06014) that seeks to clarify the conditions under which pilots can take off with frost adhering to airframes. At the same time, the SAFO might complicate the pre-takeoff decision-making process because it reminds pilots that takeoff with frost adhering to lifting surfaces and flight controls is legal.
The NTSB is recommending that pilots of Cessna 208 Caravans approved for flight into known icing conditions be required to undergo annual training for ground de-icing and flight in icing conditions. The Safety Board also wants Cessna to develop appropriate guidance materials to minimize the chance of Caravan icing accidents. The recommendations stem from the NTSB’s study of 26 icing-related Cessna 208 accidents in the U.S.
Revised Flight Standards Information Bulletin for Air Transportation (FSAT) 04-05 updates de-icing holdover times for this winter’s flying season. The tables correlate the holdover times based on temperature, type of fluid used and type of precipitation. Download the complete bulletin in Word format at www.faa.gov/avr/fsat/fsat0405.doc.
All U.S.-registered Cessna 208 Caravans are covered by a new AD, the result of several accidents during operations in icing conditions, including six accidents in the previous two icing seasons and nine events in the past few months.
Cessna Caravan 208B, Winnipeg, Manitoba, Oct. 6, 2005–Icing conditions were present when the Caravan, operated by Morning Star Air Express under contract to FedEx, crashed after takeoff from Winnipeg International Airport at 5:40 a.m. en route to Thunder Bay, Ontario. The ATP-rated pilot, the sole occupant, was killed. She was instructed to turn right on course after departing Runway 36.
As I prepared to pen yet another article dealing with winter operations, the realization hit me that we will likely have ice-related accidents. It seems that every winter we are peppered with articles dealing with many of the issues that need to be addressed to maintain safe flight under some challenging conditions.
