EDIT: Helps if I read other peoples posts. The link DJPacro sent is really just a summary of the below.

Just quickly - This is not advice and you should seek further professional advice from your authorised tax agent ( )
K with that aside. I assume you are looking to do this to realise a tax loss to offset against your other income.
I see two issues with this (which I haven't researched or looked into, this is remembering back to uni and a couple of seminars i have been to since)
1. To prove that this is not a hobby and is a valid business (or psi or whatever) you would need to prove it as such (ie. frequency, nature etc).
see here: Am I in business?
2. From memory you would not be able to offset against other income without passing certain tests (maybe you would pass the $100k asset test if it is an expensive aircraft but probably not the rest of the tests). Only once those tests are passed can you offset against income.
Anyways, I am a superannuation accountant so see a tax accountant for more specific advice (I guess that really just made this whole explanation a waste of time).
