I agree, put it on your CV by all means, but leave it for the Hobbies and Interests section. I put down that I was learning to fly, on the way to gaining my PPL - on an appl. form and it was a great talking point in the interview. During my interview, we briefly covered the mandatory questions before spending most of the time talking about PPL training.
Consequently, I really enjoyed the interview, as I felt comfortable talking about it and my interviewer was genuinely intrigued, since he wanted to learn how to fly.
I got the job - shame it's not as easy to get a flying job!
