What happened
On 23 September 2022, a Wag-Aero Sportsman 2+2 seaplane was conducting a local visual flight rules (VFR) flight near the Rivière-Bonnard aerodrome (CRB4) in the Passes-Dangereuses territory, Quebec. The aircraft, carrying a pilot and one passenger, departed from Onistagane Lake.
While the aircraft was approximately 5 nautical miles west of Onistagane Lake, the left wing separated from the fuselage. This structural failure led to an uncontrolled descent, and the aircraft struck the terrain. The impact destroyed the aircraft, and both occupants were fatally injured. No fire was reported following the crash.
The investigation
The TSB conducted a Class 4 investigation into the accident. This type of investigation is limited in scope and focuses on establishing the sequence of events and the immediate circumstances surrounding the occurrence.
