Fuel figures seem rather odd, cost too low?
100 hourly $2000.00
Good luck achieving $2,000 as an average per 100 hourly on a 25 to 30 year old airplane!!
How about radio, electrical, instrument, tires, corrosion and 100 other reasons why costs are extremely difficult to predict.
Engine (replace every 5 years) $27000.00
If you are flying only 100 hours per annum you won't be replacing the engine every five years. But when it does come to overhaul I suspect the bill will be closer to Aus$35,000 to Aus$40,000 with new cylinders, if there are no major component or crankcase repairs.
What I can predict is that there will be two wonderful days in your life - the day you buy and the day you sell.
