If you knew the latest rotor brake design on the EH101 and knew why the last crash occured you would not have started this thread unless you just wanted to stir things up that were inconsequential.
Apply torsion to a shaft and it will break (eventually).
Wait long enough and zuckerman will bleat on about FMEA conducted before colour TV was available.
Get up to date please before making statements about a current ac that you were involved in long ago.
I guess in your reply you will go about how long you worked on the 101 blah blah blah. Name a few names blah blah. But its ALL out of date with regard 101.
You have a lot to add to the forum about your current work but please stay up to date or back off.
