Fuel cost to operate: ~$10 an hour

Probably closer to $18/hr. It'll burn about 6 gph in cruise, and fuel runs 2.65
to 3.05 at the small fields around here.

Insurance: ~$1,000 a year, but I have no basis for that figure other
then some poorly remembered usenet posts.

It may be a bit more at first, but it will go down a bit over time. Probably
wind up closer to $800 once you get a few hundred hours in the plane. You can
get a better idea from Chris Wolbert at 301-682-6200. He's a broker.

Tie-down: ~$50 a month? Total guess, based off taking the average
tie-down cost in Wisconsin ($35) then adjusting it for longitude.

Call a local airport and find out. They run $85/month near the New Jersey coast,
and there are places not far away that are considerably higher.

TBO: $8,000 - I couldn't actually find anyone saying how much they
spent having their O-235-L2C overhauled.

More like $14,000.

I know I'm missing something, but I can't figure out what.

Annual inspection. Again, you should call a local shop for better figures, but
$500 is probably close. You should also allow a few hundred dollars a year for
unexpected maintenance.

If you *really* want to know what it costs, also add in the interest on any loan
you have to take *or* the amount of interest you would receive from investing
the money. Many of us deliberately ignore this, arguing that the plane will
increase in value. Your choice.
