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.
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.
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.
Sen. Rick Santorum (R-Pa.) has submitted legislation that would prohibit the National Oceanic and Atmospheric Administration and the National Weather Service from providing weather forecasts to the public when a private firm can do so. S.786 is designed to keep the government from competing with private industry.
Mitsubishi MU-2B-36, Pittsfield, Mass., March 25, 2004–The NTSB determined the cause of the accident was “the pilot’s loss of aircraft control for undetermined reasons, which resulted in an inadvertent stall/spin and subsequent impact with the ground.”
Cessna 425 Conquest I, Bozeman, Mont., Nov. 29, 2005–Salt Lake Center had cleared Conquest N701QR for the procedure turn to a holding pattern at 12:40 p.m. and told the pilot to contact Gallatin Field, his destination. The pilot, the sole occupant, read back the clearance correctly and there were no further transmissions. The airplane disappeared from radar at 5:40 p.m. and crashed on a ranch. The pilot was killed.
Beech King Air 90, Rawlins, Wyo., Jan. 11, 2005–The NTSB said the air ambulance accident was caused by “the pilot’s inadvertent flight into adverse weather [severe icing] conditions, resulting in an aerodynamic stall.” A contributing factor was the pilot’s inadequate planning for the forecast icing.
Eleven years after the October 1994 crash of American Eagle Flight 4184 in Roselawn, Ind., the FAA proposed a revision to Part 25 certification regulations that aims to prevent such icing accidents. The comment period for the notice of proposed rulemaking (NPRM) closed on February 2. Now the new rules will begin to wend their way through the FAA rulemaking process.
