Narrative:
The P-3 Orion departed Brunswick at 12:05 on a flight to Trenton, where it was to take part in an airshow. Some eight to ten minutes later the aircraft crashed in flames.
Reportedly, the nr. 1 engine experienced a "whirl mode" failure in turbulence. The nr.1 engine separated from the wing, along with an 11 feet outboard portion of the port wing. The wing part struck the port horizontal stabilizer, shearing it off. Aerodynamic forces then caused the (downward) separation of the remaining three engines. The starboard wing folded up at the wing root and broke away. The remainder of the aircraft rolled inverted and impacted the ground.


Classification:
Wing failure
Loss of control
