Just learned a new thing today which is not in the books i.e. flight manual... If the free-wheel unit on one engine fails then the first indication is a C-Box chip light, followed by a torque split and subsequent drop in NR... The scary thing on all this is that the NR will drop into the basement with no chance to recover from that. Thus, the ship will drop out of the sky like a rock if one waits too long to put the aircraft on the ground.
