Getting in a bit late, just found the 214 thread.
If I remember right the real cause of the incident of the 214 that sheared a tail rotor driveshaft was that the pilot didn't realise that net that carried the load he was trying to lift had got hooked to the vehicle the load was on. Not noticing the torque gauge go off the clock the first thing the pilot knew was that the tail rotor drive shaft sheared. His reactions were quick to say the least. The aircraft was 755 on the SOAF register. It took us (I was one of the engineers there) many months to get that one back in the air. I still have many photo's of the 214 in the air together, all five that we had at that time. From the length of time RedandWhite spent flying the 214 in Oman I am fairly sure I know who you are!
