Probable cause
A total loss of engine power due to a loose torque meter attachment nut in the reduction gearbox that jammed the planetary gearset causing the power turbine shaft to separate from the power turbine disk, resulting in the power turbine overspeeding and shedding blades that penetrated the compressor turbine case.
