When I was young? Well, our basic course (Whirlwind 10) syllabus required us to complete a solo "engine offs" sortie , after about 40 hours TT on rotary wing.
Once the flight idle stop switch was selected to "ground" and the throttle on the Gnome turbine was closed, there was no powered recovery to a hover available, in fact the regulations prohibited it.
Might have been less hours than that, I'm not sure what the exercise numbers in my first logbook mean now. I blame the passage of time (well, it was 32 years ago). "Teeteringhead" might remember.
As far as I know, a student never bent one whilst flying solo EOLs.
