Not as unlikely as you think.
AS-350, As-355 and Hu-300 were prone to it to name just 3.
The AS-350 and AS-355 on fixed floats loved to dance!
Not used perhaps in The RAF / RN true.
Never heard of it on the Bell 47, 204, 205, 212.
Seems to occur on 3 bladed of more aircraft…which, by definition makes sense.
