Al is pretty much bang on with those figures as a guide. I have a Skyhawk XP with a 200hp engine and wobbly prop. So the prop costs have to be factored in. My hangar and insurance is a lot less so balances his figures.
I fly 350-400hrs a year so my fixed costs have a greater number of hours to be spread across and I don't run an engine fund.
A rough guide would be about £60 per hour for mine.
A regularly flown aircraft by a carefull pilot actually has lower maintenance costs in relation to a hangar queen. My aircraft costs nearly 10k a year for aboyt 15hrs flown before I got it. Stood around outside not being used things just failed. Now it is wear and tear stuff that goes wrong, like tyres and the stupid starter spring on the continental starter.
