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.
Just as the cold weather starts to take hold in the higher reaches of North America, Sikorsky’s S-92 has passed one of its critical remaining airworthiness tests: crews with Cougar Helicopters in Canada are now cleared to fly their aircraft into known-icing conditions.
A jury decided in favor of Cessna in a lawsuit arising from the Oct. 10, 2001, crash of a PenAir Caravan near Dillingham, Alaska. The plaintiffs, survivors of the 10 people killed in the crash, claimed the Caravan has design defects that make it dangerous to fly in icing conditions, but the jury found “no defects” contributed to the accident.
Cessna Caravan 208B, Bellevue, Idaho, Dec. 6, 2004–The NTSB blamed the fatal accident of the Salmon Air Caravan on the pilot’s failure to maintain aircraft control while on approach for landing in icing conditions. Inadequate airspeed was a factor.
Apparently, it’s just a time-honored myth that the Inuit language of native Alaskans has as many as 400 different words covering all forms of frozen precipitation. In fact, there are about a dozen, just like in English.
Sikorsky’s S-92 equipped with the OEM’s new rotor ice protection system (RIPS) has been FAA certified for flight in known icing conditions. Sikorsky is seeking S-92 RIPS certification from the EASA and Transport Canada. A Cessna Citation involved with the S-92 icing program in Alaska on September 30 flamed out in icing conditions and made a deadstick landing with no serious injuries to the four people on board.
A University of North Dakota (UND) Cessna Citation II icing research aircraft made a successful deadstick landing near Beaver, Alaska, about 70 miles north of Fairbanks, after both engines lost power on September 30. In IMC at 9,200 feet, the Citation accumulated about seven-eighths of an inch of ice on the wing’s leading edge.
