GATINEAU, QC, Sept. 14, 2012 /CNW/ - The Transportation Safety Board of
Canada (TSB) released today its investigation report (A11O0166) into
the stall and impact with water of a Georgian Bay Airways Found Bush
Hawk-XP aircraft that occurred in Parry Sound, Ontario, on 8 September
Following take-off, the aircraft pitched up and turned to avoid rising
terrain. As it turned, the aircraft entered in an aerodynamic stall at
an altitude from which recovery was not possible, and struck the water.
The pilot and 2 passengers quickly escaped the aircraft with minor
In its investigation, the TSB found safety issues related to aircraft
performance and the risks associated with incomplete weight and balance
calculations. Specifically, the investigation found that while the
actual weight was under the maximum gross take-off weight, it was much
closer to the maximum than the pre-flight estimate. It also found that
the aircraft centre of gravity was beyond the limits of the aircraft.
When aircraft loads are not weighed, or when weight and balance are not
properly calculated, the result can be an attempted take-off with the
centre of gravity outside of the prescribed limit for the aircraft -
which increases the risk of control difficulties. The operator,
Georgian Bay Airways, has since installed a 2000-pound scale at the
main base to ensure that all cargo is weighed, rather than estimated,
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.
