Not heard of that one prior
crab, if you were of neurotic bent there is plenty to worry about, chap had vibrations (F-28) so went into power on auto to get to the ground as quick as possible, flared, nice landing, during the cool down the passenger said "Looks like someone has been here before us", pointing to a tail rotor in the bushes. Pilot climbed out to find the end of the tail boom had been chopped off, but couldn't see how it could possibly have happened. Turned out the forward bolts on the transmission had sheared and when pulling power to terminate the transmission rotated rear wards so chopping the boom, on lowering collective transmission fell back into place. Manufacturing fault in machining the bolt holes placing stress on one side of the bolt heads.
Always had thoughts of one of my instructors and Groomsmen, Jerry Hardy ex RN, who died in a Bristow 76 at Aberdeen when it threw a blade. Doesn't take altitude to kill you. Jerry on right doing the mail run for the
HMY Britannia when the ship visited Oz 1970.
