Maule Turbine

[kevin]

Does anyone have any experience with the Maule with the Allison turbine
engine ? The Maule with the Lycombing IO-540 is $170.M , where the
MT7-420 is going for $470.M new. I would have to add about $75.M in
options for either bird. What do you think about the Allison turbine in
a Maule ?

Thanks

You are joking, right?
Look, the Maule is a fine airplane and does it's thing well, which is short
field and grass operations... It is not a turbine bird, and installing one
is a waste of money... Unless you are going into the bush of africa or asia
where 100LL is not available, stick to the Lycoming...

The turbine carries 35 pounds more and takes the same distance to clear a
50' obstacle. The major difference is the 2800 fpm climb rate versus the
1500 fpm for the piston engine. The turbine goes for $450,000. There are
several models of 235 hp planes, one of which costs $139,600.

So. That climb rate will set you back over $300,000 and burn twice as much
fuel. It wouldn't be worth it to me.

Seems like a very fine toy. Wish we had one... let's see, we've got Jet-A
on our lit grass strip. Imagine a night landing in the back yard with the
whine of that turbine as we select beta thrust. Wheeeee!

.... perhaps add some amphious floats.

Just need to increase our wealth by an order of magnitude... or two.

You might also want to check into the status of the diesel they've been
trying to get certified. That should be a reasonably priced aircraft
with performance similar to the 235 but using jet-A. I spoke with Ray
Maule about it last year, and he said it was going well, but I don't see
anything about it on their web site anymore.

From AvWeb:

This week at OSH, Maule debuted an M-9 fitted with SMA's SR 305-230 aerodiesel,
which was first certified in Europe a while ago and is now poised to make
inroads in the U.S.

I was not talking about a conversion, you can buy a new Maule from the
factory with the Allison engine. I was looking at the difference of
cruise speed 164 with the Lycoming as opposed to 190 with the Allsion.
The 2800 fpm climb is also tempting.

One big difference is the cruise speed 164 for the lycoming, and 190
for the Allison. But as you say the price difference is huge.

The slower Maule will go a lot further between fill ups.

This is true. 15gph as opposed to 25 for the turbine.

15 vs. 25gph for different speeds, right? What are the fuel consumptions
for the same speed at cruise altitudes (10-20K)?

To be fair you should also add in the extra 5 gallons the turbine can
carry (in situations where you're at gross).

You might want to have the factory take you for a ride to see what 190mph is
like inside of a fabric covered fuselage with angular otlines....

Yes , without a doubt i would want a demo ride. A cruise speed of 164 is
not bad for a
STOL bird, 190 is smoking.

[Dennis O'Connor]

I recently flew a local pilots, new 260 Maule... I didn't see anything
approaching 164...

Thats what the specs say on the 260 with the IO-540 Lycoming. What
cruise speed did you see ?

Odd - I've found the Maule Air specs to be quite accurate on my bird. You
*do* realize that we're talking miles per hour and not knots?

I spoke with SMA (France) last week, at their tent at Oshkosh. They said
currently only Jet-A is certified. Diesel is not approved. Too many BTU's in
diesel, from what I understand. To many variations in diesel fuel. (Their
words)

Diamond Star's diesel burns Jet-A or regular diesel fuel and is certified as
such. Their engine is made by Thielert of Germany
