Circumstances:
The float plane was observed on take-off and initial climb before it disappeared behind a point of land. Shortly after, it impacted the surface of the lake in a left wing low attitude with considerable slip to the left. Reports describing the noises coming from the engine immediately before impact, are conflicting. Examination of the propeller indicated there was little or no power being developed at impact. Engine examination indicated it capable of producing power at impact. (lp 233/83 refers). The aircraft was fitted with an external fuel tank underneath the fuselage, but the log books and the weight and balance did not reflect this addition. An unapproved bench was installed in the centre cabin area, and the aircraft had no visible means of load restraint.

Circumstances:
On approach to Toronto-Lester Bowles Pearson Airport following an uneventful flight from Philadelphia, the airplane rolled left and right then lost altitude and crashed in a field, bursting into flames. The wreckage was found 13 km from runway 24R threshold. The aircraft was destroyed by impact forces and a post crash fire and all five occupants were killed, among them Ross Henningar, President and CEO of Sun Oil Company (Sunoco).
Probable cause:
Loss of control on approach following an internal failure in the low pressure compressor of the right engine while the left engine flamed out and was windmilling at impact. Investigations were unable to determine the cause of these occurrences. It was also noted that the anti-icing systems were not activated prior to the accident while icing conditions have been forecasted.

Aircraft flight hours:

Circumstances:
The twin engine airplane departed Toronto International Airport Runway 23R at 1351LT on a local VFR training flight. On board were three Civil Aviation Inspectors, the Captain occupying the left seat, the Check Pilot the right seat and an observer pilot the right forward cabin seat. The flight was for the purpose of checking the proficiency of the Captain and renewing his instrument rating. After being cleared to climb to 3,000 feet, at 1358LT, the airplane was 22 NM from Toronto and the crew was instructed to clear the frequency. Shortly thereafter the flight test commenced. One of the exercises intended was a simulated approach and overshoot with a simulated engine failure during the overshoot. During a second such exercise, the right engine was shut down and an overshoot was commenced. Subsequently a ground witness observed that the right propeller was stopped and that a stream of black smoke was coming from the left engine. As the aircraft commenced a shallow descending turn to the right, the smoke diminished. It continued to descend striking trees before the right main gear and nose impacted the ground. The accident site was located 43° 22' N 80° 08' W, south of Valens, ON. A crew was seriously injured and two others were killed.
Probable cause:
The following findings were identified:
- After the right fuel lever was selected to the OFF position to simulate an engine failure, the fuel lever for the left engine was inexplicably moved to the OFF position.
- Under these circumstances the altitude above ground level selected for engine shutdown using the fuel shut-off lever provided insufficient margin for safety.
- The crew was current on type according to DOT operating requirements.
- Improved Transport Canada requirements and operational control would help to prevent recurrence of this type of accident.
