Better is a relative concept.
After the sheer number of attempts RHC have had producing a reliable blade design, they seem determined to snatch defeat from the jaws of victory.
Some may consider this a rather important part of a helicopter, so why they continue to produce something that could be bettered by a small group of children with glue and duct tape is somewhat confusing.
Could you imagine if any other manufacturer had the same approach to client safety and satisfaction?
Perhaps the bar just isn’t set that high for the piston market.

As a result, I suspect we are going to see more reports of problems with corrosion, debonding, delamination, call it what you will.

This problem goes back many years.
