Cost of ownership and operation for the ATG Javelin aircraft

[Wolfala]

I've been doing some poking around and noticing how the ATG Javelin went from $1.2 Million to $2.7 for no explainable reason. And was wondering...for those of you drivers who currently own an aircraft - what do you have to consider into the cost of ownership for something like this?

Just a rough spec of 2× Williams FJ33-4-18M turbofans runs at about 40-50 gals per engine per hour, so figure @ $4.50 / gal JP-4, between $350-400 for fuel per hour of operation.

Fuel: $350-400.00 / hr
Maintnence labor reserve: $77.00 hr
Parts reserve: $67.00
Total variable cost / hr operation:  Approx $500.00


Fixed annual costs: (used the PIDOOMA theorym for this - could be totally off)

Hull Insurance: $40,000.00
Liability: $8000.00
Maintnence Software: $3,000.00
Misc service: $2,000.00


Periodic costs:

Midlife/hotsection: $33,000.00
Overhaul (engine): $100,000.00 each (every 3500 hours)
Paint: $20,000.00

Training: $10,000.00
Maint tech: $6000.00

Hanger lease:  $23,000.00

Did I miss anything?

If you need to consider the costs...you can't afford it.

Half a mo...

at 50 gal per engine per hour, and a 3.5 hour air time... that thing holds 350 gallons? where the heck does it go?

[Debonair]

FL450, you get a lot of glide range from up there...is the endurance number with any reserve?

[Seagoon]

At that cost, wouldn't a surplus Hawker Hunter be less expensive to purchase and maintain? Plus it only has one RR engine to worry about maintaining...

In a word...parts...

Wolf, what Curval said hits it....if you have to ask, or budget it, ya cant afford it.  When it comes to the world of personal fighter-type jets, there are no seats in economy.

Also, I havent seen it mentioned in the Javelin site...but if that thing offers ejection seats, pyrotechnic inspections/maintenance is pretty steep.  A lot of L-39C sites boast $400~ish per hour costs yet dont mention the seats.  A few sites do, as a subnote, hinting that its a $30,000 or so cost.  I beleive those seats (Correct me, Gunslingr) are 0/0 rated?

[Wolfala]

Well what i'm thinking is sort of a high end point to point air taxi or upscaled version of Air Combat USA. So whether or not I can afford it is irrelivant at this point in time. All that takes is a walk up Sand Hill Road with a business plan. What I am trying to figure out is something that isn't as short leg'd as an L-39 (i.e. has more then 20 minutes of fuel) and can be fitted with a 0/0 seat - probally a Russian design.

So, the question is still valid - for those who own aircraft, what are the other costs I havn't included? The insurance figure is identical to that of a Super King Air 200, which actually burns 20 gals an hour more and cruises 200 kts less.

I think you might be low on the insurance.  A King Air 200 is not really comparable.  There are a lot of them and they have a good safety record.  For an exotic ride like this I would be surprised if you could get hull coverage for 5% of the insured value, but if you could it would be $135000 a year or $450 an hour if you flew 300 hours.

[Wolfala]

So the way insurance works, the more exotic the ride and lower total hours flown, the higher the rate? Is there mandatory coverage amount that is required nationally, or is it just setup state by state?

[Furball]

What about a couple of JP's?

Should be cheap, and parts easy enough to get.

Yeah, the insurance depends on what you are flying, who is flying it and what you are doing with it.  We are sprayers and I think we had to pony up 7 or 8 percent of hull value for hull coverage this year.  The assumption is, of course, that the probablility of a hull loss incident is higher.

I just picked 5% out of thin air but in general terms rate will increase wherever the underwriters sense risk and a Mach .9 twin turbojet without a proven safety record will make them nervous, especially if you don't have a Chuck Yeager type flying it.  I would be astounded if you could find someone to write the hull for 5%.

That's just for the hull insurance.  Liability is another issue.  I am not aware of national or state requirements like there are for, say, car insurance.  You want the limits high enough to protect your assets if you wind up in front of Judge Wapner.  Policies can be written that categorize various limits for various things or can be written as what's called "smooth".  An insurance policy of 1 million smooth means that the underwriter is obligated for up to a million dollars of loss for the policy.  Anything over that is on you.

Insurance doesn't work on hours flown so once you cut a deal the more hours you fly the cheaper it is per hour for insurance.

You might check with Avemco which is the largest general aviation insurer.  If you hear crickets chirping after saying ATG Javelin you might check with USAIG.

Best of luck.
