of a Robinson R22 helicopter crash in November of 2011, the
Transportation Safety Board of Canada (TSB) today released its report
(A11O0222) on the accident near the Region of Waterloo International

On 28 November 2011, the helicopter was departing the Region of Waterloo
International Airport, Ontario, for a local training flight with a
student and instructor on board. Approximately 1 minute after take-off,
the helicopter crashed in a drainage swamp on airport property, fatally
injuring the instructor and seriously injuring the student.
Following a series of accidents and incidents, the Robinson Helicopter
Company issued safety notices to its operators to reduce the likelihood
of carburetor icing. These are published on its website and at the back
of the pilot's operating handbook.
The TSB is an independent agency that investigates marine, pipeline,
