Examination of the engine at TCM found the crankshaft fractured through the number one connecting rod journal forward fillet radius and upper counterweight hanger blade. The rear upper crankshaft counterweight was detached from its hanger blade. One plate and snap-ring was forced from their locations on each side of the counterweight by mechanical action of the pins. The counterweight plates of this counterweight were bowed outward in relationship to their installed positions. One of the snap-rings was fractured in two pieces and both snap-rings that were not in place exhibited signatures of being forced from their retaining grooves in the counterweight. The remaining rear counterweight exhibited sever mechanical damage and was intact on the hanger blade. The forward set of counterweights, pins, plates and snap-rings were intact and undamaged and had free and unrestricted movement on the hanger blades.
