Circumstances:
Shortly after takeoff from runway 03, while in initial climb at a height of 30 feet, the right engine lost power. In the mean time, undercarriage was retracted. The speed decreased, the aircraft banked left and eventually crashed in a field located half a mile from the airport. Five passengers were killed while nine other occupants were injured. The aircraft was destroyed.
Probable cause:
The reason of the loss of power on the right engine was not properly determined. However, this occurred at a critical stage of the flight, just after rotation. As the crew was unable to feather the propeller, this increased drag, reduced speed and caused the aircraft to stall.

Circumstances:
Shortly after takeoff, while in initial climb, the left engine exploded. The crew attempted to return when, during the last turn at 115°, at a speed of 80 knots, the left wing stalled and hit the ground. The aircraft cartwheeled and crashed some 600 metres from the runway end, bursting into flames. The stewardess and seven passengers were killed.
Crew:
Claude H. Seaton, pilot,
Malcolm Wallace, copilot,
Louise Zarr, stewardess.
Probable cause:
A stall, induced by a violent yaw, resulting in loss of control from which the pilot was unable to recover.
Contributing factors are:
Failure of hold down studs on the number six cylinder of the left engine which resulted in the cylinder being forced off, carrying with it the lower third of the engine ring cowling. Displacement of the remaining portion of the left engine ring cowling, which caused buffeting, as a result of disturbances of the air flow over the tail surfaces, and increased the drag on that side of the aircraft. Severe vibration induced by the continued rotation of the propeller. Lack of individual propeller pitch controls which would have permitted the pilot to increase the pitch of the propeller on the inoperative engine, thereby reducing the speed of rotation and consequently the vibration from the effect of "windmilling".
