What happened
The incident involved a single-engine airplane operating out of Shepard Field in Calgary. The aircraft was on a mission for a wireless training exercise and carried six crew members aboard. During the flight, the pilot executed landings as part of the exercise.
Upon the initial touchdown, the aircraft experienced a bounce. When it made contact with the runway surface a second time, the starboard wheel remained locked. Examination of the track left by the port wheel indicated intermittent braking action or mechanical failure in that area. Due to these conditions, the airplane lost stability and came to rest upside down on the ground.
All six individuals on board were slightly injured in the accident. The crew consisted of a pilot, a wireless instructor, and four wireless operators.
