A local training flight out of Sudbury ended in a crash into Ramsey Lake after the aircraft stalled during a sharp turn at low altitude, resulting in one fatality and one injury.

What happened

The incident involved an aircraft conducting a local training flight originating from Sudbury. During the maneuvering phase of the exercise, the crew was executing a sharp turn while flying at a low height. At this point, the pilot lost control of the airframe. The loss of control led to an aerodynamic stall, causing the aircraft to descend rapidly and impact the surface of Ramsey Lake, located off Sudbury.

The crash resulted in significant casualties among the occupants. One pilot was killed in the accident, while a second individual sustained injuries.

Probable cause

Loss of control during a sharp turn at low altitude leading to an aerodynamic stall.
