On 30 June 2011, the pilot flew from Southend, Saskatchewan, to a remote fishing cabin near Buss Lakes to pick up four passengers. The aircraft departed Buss Lakes but then crashed along the shoreline of another lake about two nautical miles southeast of its point of departure.

"The aircraft entered an aerodynamic stall," said Peter Hildebrand, TSB's Manager, Regional Operations, Central. "The stall occurred at an altitude from which recovery was not possible."

An aerodynamic stall occurs when the airflow over the wings decreases to the point where the wing starts to lose lift. Recovery from an aerodynamic stall is accomplished by increasing airflow over the wings by adding engine power and returning to level flight or pitching the aircraft downward.
