Circumstances:
The four engine airplane departed Brunswick NAS, Maine, at 1205LT on a flight to Trenton, Ontario, where it was dispatched to an airshow. While climbing, the crew encountered poor weather conditions with stormy weather when the engine n°1 went in whirl mode and detached. 11 feet of the left wing separated and struck the left horizontal stabilizer that was torn off as well. Out of control, the airplane entered a dive and partially disintegrated before crashing near Poland. All eight occupants were killed.

Probable cause:
It was determined that the engine went into a whirl mode which corresponds to a low frequency vibration in the engine mounts that can cause the separation of the engine in flight. It is believed that weather turbulences may affect the proper functioning of the engine.
