What happened
The incident occurred during a local solo test flight conducted by a civil pilot departing from Saint-Jean-sur-Richelieu Airfield.

While operating north of the city, the airplane collided in mid-air with a second aircraft, identified as a Royal Canadian Air Force Anson registered 6196.

The wreckage came to rest approximately 5 km south of Chambly. All five occupants across both aircraft were killed in the crash.
