Old Bells are a different design when it comes to load paths and there have been plenty of "issues" over the years. 47 relies on an internally threaded grip? A few have been shucked due to cracks deep within the threads.
The design is question is similar to the H500 - there are no blade retention loads in the "pitch housings".
