question about engines

Jim pretty much hit the nail on the head.
During WWII there were a huge number of radial engines produced, more than
were needed. The surplus engines were readily available until recently.
The current trend of ag and seaplane operators switching to PT6's is
primarily a direct result of the depletion of the inventory of WWII era new
pickled engines. As they became harder and harder to obtain, operators were
forced to choose between overhauls, rebuilds, new radials, and PT6s. Our ag
operator was simply not satisfied with high price and high maintenence of
the new raidals nor the quality of the overhauled and rebuilt engines,
cylinders, and other components and has began the switch to PT6s.

Meanwhile - I've seen KingAir conversions replacing the PT6's with
water-cooled V8's!They make all kinds of claims for performance improvements.

Cool! Got any links?

Good morning,

There was some press about an outfit that was developing a conversion
to swap the King Air's PT6 turboprop engines for V-8 piston engines. I
think the name of the engine was spelled something similar to "Oreneda"
or something vaguely like that. I have not read anything about it in
the past year or so, never seen a real one, and there is nothing that I
can find on the net about it ( perhaps someone more proficient with
Google would have success). Given the near bullet-proof reputation of
the PT6, maybe it was just too hard to sell, despite the cost of
dealing with timed-out turbines.

Blue skies . . .

That's it :

I agree they seem to have quieted down a lot over the past couple of years.
Sure doies seem like a hard sell - the principal attractiveness of a KingAir
is the performance and reliability of a pair of PT6A's - then to go and put
recuiprocating engines in it . . .

look for Thunder engine

The same engine as in the Thunder Mustang? Sheesh, I know the plane
has eaten some folks' lunches . . . but what a beauty

Nobody with a brain cell left takes turbines out of a King Air and puts
in pistons.

Hi John

I was the primary draftsman for the Thunder Mustang. To date I only
personally know of about 4 of them that are flying. I suspect there
another 4 or 5 I don't know about. From the parts and engines we
manufactured there could be as many as 25 of them flying.

To date the only accident involving injuries that I am aware of was the
crash of the prototype.
Have there been any more accidents?

I have to admit the when we put it paper it was pretty obvious it was a
hot airplane and that people would kill themselves in it. I am bit
surprised it hasn't been worse. But maybe the fact that it is obviously
a hot airplane that deserves respect has contributed to this.
