TSB releases report into Toronto/Buttonville crash
March 19, 2012, Gatineau, Que. - The Transportation Safety Board of Canada (TSB) on Friday released its investigation report (A10O0240) into the 18 November 2010 loss of control and collision with terrain of a Beechcraft Bonanza F33A, operated by the Seneca College of Applied Arts and Technology near the Toronto/Buttonville municipal airport.
The aircraft left the Buttonville airport on a flight to Kingston, Ontario, with an instructor and two students on board. Weather en route began to deteriorate and the flight headed back. On radar, it was observed to be westbound in level flight before it turned north and began to climb. The aircraft then turned abruptly to the left and descended. It was located in a ploughed field approximately 10 miles east of the Buttonville airport. It was destroyed on impact. The three occupants did not survive.
