A Canadair Canso aircraft sank in Ashuanipi Lake, Labrador, after a float caught on the water surface during a training maneuver.
What happened
In 1953, an incident occurred involving a Canadair Canso while performing a practice landing at Ashuanipi Lake in Labrador. During the approach, the starboard float of the aircraft made contact with the water surface in a manner that caused it to dig in. This impact triggered a sudden swing of the airframe.
As a result of the uncontrolled movement, the aircraft rapidly accumulated water and eventually submerged. The aircraft settled on the lakebed at a depth of approximately 200 feet. Despite the severity of the sinking, there were no fatalities or injuries reported during the event.
Findings
The primary factor in the accident was the starboard float digging into the water surface during the landing attempt.
Probable cause
The aircraft sank after the starboard float caught the water surface during a practice landing maneuver.
