Cessna will offer a TKS “weeping wing” anti-icing system for the Cessna Grand Caravan beginning next March. The system, manufactured by Aerospace Systems & Technologies, includes TKS panels (titanium laser-drilled with thousands of tiny holes) installed on the leading edges of the wings, wing struts and horizontal and vertical stabilizers.

Cessna will offer a TKS “weeping wing” anti-icing system for the Cessna Grand Caravan beginning in March, using a system manufactured by Aerospace Systems & Technologies of Salina, Kan. The Cessna system includes laser-drilled titanium TKS panels installed on the leading edges of the wings, wing struts and horizontal and vertical stabilizers.

Flight-testing of the Boeing 787 electro-thermal wing ice-protection system, jointly devised by Boeing, GKN Aerospace and Ultra Electronics, is to begin following completion of ground trials in the Boeing research aircraft-icing tunnel. Used for the first time in a U.S.

Summer is almost upon us in the northern hemisphere, but the FAA is embroiled in two significant icing-related issues: a proposed new rule for when de-ice systems are activated and a new interpretation of the term “known icing.”

The FAA issued a Notice of Proposed Rulemaking (NPRM) last week that, if enacted, would require manufacturers of newly certified transport-category aircraft (Part 25) to incorporate an ice-detection system. The proposal is part of an ongoing effort by the FAA and NTSB to reduce accidents as a result of icing, and it comes on the heels of an NTSB recommendation that aircraft boots be activated immediately upon the first sign of airframe icing.

A proposed AD would require the installation of deicing boots on the landing-gear struts of nearly 750 U.S.-registered Cessna 208 Caravans, as well as other changes to deicing equipment and procedures contained in a 1991 Cessna accessory kit. The directive stems from the FAA’s investigation into nine incidents within the past few months and six accidents in the previous two icing seasons.

Every few years, a debate erupts about whether the phenomenon of ice bridging is real or something questionable that pilots discuss while hangar flying or warning of the dangers of flying in icing conditions. The issue recently resurfaced at an NTSB public meeting about the icing-related crash of a Cessna Citation 560 in Pueblo, Colo., on Feb. 16, 2005.

Cessna Citation 550, Fort Yukon, Alaska, Sept. 30, 2005–The NTSB has concluded that the University of North Dakota icing research jet accident was caused by the pilot’s improper use of anti-icing equipment during cruise, which resulted in ice ingestion into both engines and the complete loss of power. Factors were the icing conditions, inadequate crew resource management and failure to use a checklist.

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.
