Probable cause
The pilot's failure to adequately secure the external load rigging of an airplane that was suspended from the helicopter, which resulted in a load shift during cruise flight, producing an abrupt nose-down attitude, and the severing of the tailrotor drive shaft by the main rotor blades.
