The NTSB determined today that the Feb. 16, 2005 crash of a Circuit City Cessna Citation 560 during the approach to Pueblo Memorial Airport, Colo., was caused because during the approach, as they flew through a cloud containing supercooled liquid droplets, the flight crew didn’t activate the deicing boots at the first sign of ice buildup (as specified in the AFM) and possibly not at all, and didn’t monitor airspeed, which led to a stall.
In its determination of the probable cause of the PenAir Caravan crash, the Safety Board also said that a factor contributing to the accident “was the lack of a preflight inspection requirement to examine at close range the upper surface of the wing for ice contamination when ground icing conditions exist.” Such a requirement is now on the books, the result of an AD issued in March following an FAA investigation into incidents involving Carava
Deicing boots must be installed on the landing gear struts and cargo pods of several hundred Cessna Caravans approved for flight into icing under an AD published today.
It may be nearly the first day of summer, but engineers from the National Research Council of Canada are in Paris this week with thoughts of winter on their minds–or at least the most well-known byproduct of winter: ice.
Electro-thermal ice protection systems made by UK company GKN Aerospace (Chalet G1-3) have been selected for every major aircraft for which electric de-icing systems have been specified, according to senior vice president of sales and marketing Frank Bamford. Applications for which the GKN system has been chosen to-date include the F-35 Joint Strike Fighter, Boeing 787 and EH101 medium/heavy lift helicopter.
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.

An infrared de-icing system is scheduled to be operational late this winter at New York John F. Kennedy International Airport. The system consists of a large tent-like structure under which an aircraft is taxied or towed and de-iced in minutes using the energy generated by hundreds of computer-controlled infrared heating elements. Systems are now in use at Newark International Airport, N.J., Buffalo Niagara International Airport, N.Y.
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.
