NTSB CEN10LA068Accident · No injuriesLimited investigationFinal reportBeech V35 · Dodge City, KSThe failure of the pitot heat system in icing conditions resulting in an inoperative airspeed indicator which led to an inadvertant stall while on final approach. Contributing to the accident was the pilot's decision to fly into known icing conditions.NTSB WPR09LA263Accident · 2 fatalLimited investigationFinal reportLanham Lancair IV · Seligman, AZThe pilot's loss of airplane control during en route descent while operating in known icing conditions.NTSB ANC09LA038Accident · Minor injuriesLimited investigationFinal reportCessna TU206 · Bethel, AKThe pilot’s failure to remove visible frost from the wings during the preflight inspection, and his failure to maintain adequate airspeed to avoid a stall. Contributing to the accident were conditions conducive to structural icing/frost.NTSB CEN09LA206Accident · No injuriesLimited investigationFinal reportCessna 402B · Aberdeen, SDThe pilot's continued flight into adverse weather and icing conditions, and his failure to maintain aircraft control resulting in a hard landing. Contributing to the accident was the accumulation of airframe ice and the strong, gusting crosswinds.NTSB CEN09CA136Accident · No injuriesData collectionFinal reportBeech 19 · Lafayette, INThe pilot's inadvertent encounter with icing conditions during initial climb. Contributing to the accident were the lack of visibility during the landing due to an ice covered windscreen, and the structural ice that adversely affected the flight…NTSB CEN09FA135Accident · 3 fatalField investigationFinal reportGulfstream Aerospace Commander · Wray, COThe pilot’s failure to maintain aircraft control during the approach resulting in an aerodynamic stall and subsequent impact with terrain. Contributing to the accident was the pilot’s improper preflight planning and conditions conducive for structural icing.NTSB CEN09LA122Accident · No injuriesLimited investigationFinal reportBeech A36TC · Three Rivers, MIThe pilot's decision to continue the flight into an area with conditions that were conducive to icing and the loss of engine power due to induction icing.
