I seem to remember it was the BICC job. Gunter Burmeister was flying it when the tail rotor shucked itself off the aircraft and Gunter narrowly escaped tumbling all the way down the mountain side. As I recall....the aircraft had been way over-torqued prior to Gunter arriving on the job. He had come to a stationary hover as he was either setting down a load of steel or dumping a bucket of concrete....when the world starting spinning on him. The aircraft rolled over several times and fetched up agains a huge rock which stopped its rolling down the mountainside.
We came awfully close to losing Gunter that day!
