Mitsubishi garnered top bragging rights in the most recent AIN product-support survey, and the biennial pilots’ review of proficiency (PROP) seminar series is one good reason why. How many manufacturers sponsor regular owner/operator safety seminars–let alone doing so for aircraft that went out of production almost two decades ago?
The European Aviation Safety Agency in late August certified the Eurocopter EC 225 twin-turbine helicopter for unrestricted operations in icing conditions. To be able to fly in such conditions, the 11-ton, $17 million helicopter is fitted with an optional duplex-architecture protection system. The five main rotor blades are deiced cyclically by mats heated by metal resistors.
Cessna Citation 560, Pueblo, Colo., Feb. 16, 2005–The failure of the crew to activate the de-icing boots of the Circuit City Citation on approach to Pueblo in icing conditions and failure to maintain airspeed caused the crash of the airplane, the NTSB concluded. (See page 1 for full article.)
Cessna 550 Citation II, Ft. Yukon, Alaska, Sept. 30, 2005–The captain, copilot and two research scientists were not seriously injured when Citation N77ND made an off-airport, gear-up emergency landing after both engines quit simultaneously. The University of North Dakota flight was doing icing research in IFR conditions when the accident occurred.
The NTSB concluded that the forced landing of a University of North Dakota Citation 550 research jet on Sept. 30, 2005, in Fort Yukon, Alaska, was caused by the pilot’s “improper use of anti-icing,” which resulted in ice ingestion into both engines and the complete loss of power. No one was seriously injured.
During the January 23 public meeting on the icing-related crash of a Cessna Citation 560 near Pueblo, Colo., NTSB members criticized the FAA and Cessna for not updating critical icing information used by pilots and certification engineers.
In the spirit of the season, the NATA Safety First program has made available its aircraft de/anti-icing training module, designed specifically for line techs, ground handlers, flight crews and dispatch personnel. The interactive, online training provides the latest and safest de/anti-icing procedures available. NATA urges personnel to review critical issues such as training, procedures and responsibilities annually.
The NTSB’s debunking of the ice-bridging hypothesis in the conclusions of its investigation of the Feb. 16, 2005, fatal crash of a Circuit City Citation 560 and determining that the pilots did not activate the de-icing boots on the approach will take some pilots back seven years. In February 2000 the long-time policy of waiting for ice to build before activating boots got the boot.
Much has been written lately about the potential cost of not de-icing a business airplane before attempting to fly it, so we posed the question recently in our AINalerts twice-weekly electronic news bulletin, “What about the cost of de-icing? The price seems to vary wildly. What is the most you have paid to have a business jet de-iced? What type of airplane was it, which facility de-iced it, and what were the circumstances?”
The pilot flying a Cessna Caravan that crashed after takeoff on Oct. 6, 2005, in Winnipeg, Manitoba, violated operational requirements, according to the Canadian Transportation Safety Board’s final report. Among the violations were taking off at a weight greater than the legal maximum takeoff weight and exceeding the time allowed between wing contamination inspection and takeoff.
