I have broken the costs down as follows:
Total 46423 (I took out a bit of cost that isn't really relevant, hence the difference from the number I gave earlier).
Of that:
Miscellaneous 1894
Non-scheduled repairs 7845
Maintenance 10458
Insurance 3409
N reg trust costs 765
Navigation services 923
The rest is fuel, landing fees (nowhere really expensive) and parking.
I hope this helps!

Yes: parts prices are ridiculous.
