ICAO to EASA PPL with <100 hours
I've decided that in 2017 I will head out to Canada to do my PPL on Bell 47s.
I understand that by the time I complete the course, I will have about 50-60 hours if I'm an average learner -- well short of the required 100 to convert the PPL to an EASA one.
My question is, would it be possible to build hours upon return by spending a few hours' worth of lessons to learn a new type, then simply fly as a solo pilot under supervision to build hours up to 100, and then convert?
If this is not possible, what alternatives would I have other than to head back out to Canada (or the US after converting to an FAA licence), and self fly hire for a week or so every year?
For clarity, I have no intention to become a professional pilot -- I'm an aid worker/nurse, and I love both my jobs!
