RICHMOND HILL, ON, Feb. 20, 2014 /CNW/ - The Transportation Safety Board
of Canada (TSB) today released its investigation report (A12O0138) into
the August 2012 collision with terrain of a Cessna 172S in Moorefield,
At 1815 Eastern Daylight Time on 24 August 2012, a Cessna 172S, owned by
the Waterloo-Wellington Flying Club (WWFC), departed the
Kitchener/Waterloo Airport, Ontario. The aircraft flew to Niagara
Falls, then to Toronto, and back to a practice area north of the
Kitchener/Waterloo airport. At approximately 2016 Eastern Daylight
Time, the aircraft crashed into a field, 25 nautical miles north of the
airport. The aircraft was destroyed; the pilot and 3 passengers were
The investigation determined that the aircraft entered a spin in a
configuration for which spins were not authorized and that the aircraft
did not recover prior to ground impact. The investigation also found
that there was a breach in the aerodynamic stall warning horn, but the
effect on the operation of the horn could not be determined. A spin
manoeuver is preceded by a stall, and a damaged horn may activate too
late or not at all, increasing the risk that pilots are not warned of
an impending aerodynamic stall in a timely manner.
Since this occurrence, WWFC has implemented some changes to its flight
program. It has re-emphasized to pilots its policies regarding air
manoeuvers, such as spins, to be conducted only with an instructor on
board, and strengthened its ground school programs regarding airwork.
Also, WWFC has indicated that it will have GPS trackers as well as
cockpit voice recorders installed in its fleet of aircraft.
The TSB is an independent agency that investigates marine, pipeline,
railway and aviation transportation occurrences. Its sole aim is the
advancement of transportation safety. It is not the function of the
Board to assign fault or determine civil or criminal liability.
