Do you mean operational or total costs? Purely operational I am actually at about 100 USD/flight hour at 130h/a for a 1967 172, total cost up slightly now to 170 USD/flight hour including depreciation for purchase and repairs. Costs will go up as I already know of a miscalculation of the costs related to engine - TCM spare part prices have been raised extremely. I expect total to be up to about 200 end of the year.
