Ok, so now I'm allowed to say this:

Radar integration
Carbon cowl
Zero bulkhead is composite....and really thick
New inertial separator, with new drive motor, can operate up to VMO
New intake plenum, seals much tighter, easy removal
Rubber inertial sep debris oulets
300amp starter, bus tied to ground power, for fast starts
Pedestal change
No 850 mode, torque scale is 0 to 100%
5 blade comp prop
New stacks
Curved dorsal to match winglets
New A14 box, with t/s diag LED's
Head cutting strakes
New power station
Lower inst panel is curved the whole length of panel
Auto pressurization
Tire covers
New yoke with more buttons than an xbox controller

We have talked about some of this stuff already. There are many changes that will ease maintenance that pilot really wont be concerned about. Looks like we are getting serial number 0003. Ill have more I'm sure.

Socata as spent $30m US to develop the TBM 900.
$3.7m is what they need to stay in business, they will sell them all 40-50 a year.


I am, in no way, saying that SOCATA might have a financial problem. They belong to a large group and the AIRBUS biz must bring them a lot of cash.

Having said that, selling 40/50 900 a year is another story.In the 3.5/4.5 millions bracket business plane there is a lot of competition from VLJ to PILATUS going through KING AIR.

Let see.

What is zero bulkead in composite?

The inertial seperator operating to VMO is very good, a lot of time I need to slow down in descent to under 200 kts as I forgot to deploy it, I saw that the VMO is now 270 vs 266, is that true? What have they changed?

The zero bulk head is the very front bulkhead where the hydro generator and NACA ducts are attached. Its right by the mount vibration isolators.. Im not sure the exact VMO, you number sounds right. But as I understood all of the increases come from improved aerodynamics. If you are asking what they changed in the inertial separator, the motor that drives the flap is huge, much more powerful, and made in the USA. Also, they simulated airflow through the I/S and changed it for efficiency. I am not a pilot, I'm just mechanic, so when it comes to numbers with acronyms I glaze over.

Doesn't matter with this TBM 900 and maybe you guys are right on the Cirrus Jet. Either way, with the Cirrus Jet and this TBM you're really stacking the marketplace with ridiculously fast and efficient, easy to fly airplanes. There's lot's of innovation going on in GA. The only thing left is to get these things to fly themselves. This is a great time to be in GA.

It is certainly true that innovation is taking place in GA. The Cirrus Jet and TBM 900 appear to be efficient and designed to be easy to fly.
What is missing is this equation is the cost parameter: could a manufacturer deliver ease and efficiency at an "affordable" price?
I realize that affordable is a relative term. If a manufacturer could use cheap labor (China) using reliable design (a la Apple: designed in California, built using cheap labor in China), why can't such an airframe be produced for a more attractive (i.e. much lower) price? :scratch:


The airframe probably could be produced at a much lower cost. Unfortunately, that still wouldn't enable them to sell them at an affordable price. Given their massive R&D and certification costs, and their low volume, recouping R&D is a huge chunk of the price. Consumer electronics companies, who sell hundreds of millions of units, don't really care about reducing R&D costs, but they are fanatical about optimizing per-unit cost (parts and assembly labor). With airplanes, it is pretty much the exact opposite.

My assumption on that figure is that the $30M estimate are the incremental costs to develop the 900 from the existing 850 (700N) Type Certificate. Incremental Type Certificates cost a fraction of entirely new Type Certificates.

Thats right, I was going to mention that. It is an incremental cert, not a new certification. They actually do a very good job of keeping their cert costs down. Also their r&d cost cant be that high either, they are re using a lot if technology and they have a massive composites back ground. Im not really sure how they could get their cost down on their airframe? I would be interested in hearing what you think of that. You might go and look to see how they produce their airframes, its not just rivets and sheet metal.

Massive automation with robotic riveting machine specialized for each part of the airframe. I'm sure with a couple billion invested they could get costs down substantially and also be able to turn out 1000 airframes per month.

Im sure you are right, automation is great, it costs money to get there, especially "massive automation". 1000 airframes per month? Thats a lot, could they sell that many? Anyway comparing an Eclipse to the TBM doesn't really make sense to me. I don't know, but I would think the maintenance on the Eclipse would be higher, but I am not familiar with it. I don't have the money for any of it, but from what I have seen, TBM maintenance is pretty reasonable. People that want two jet engines, buy airplanes with two jet engines. People that want a jet with a prop on the front buy one of those. Didn't Eclipse go bankrupt?

This thread is to talk about the TBM900, so I will continue with that.

So the pilot door is going to standard now, but they are still going to produce them with no pilot door as an option....at least for now. The pilot door is awesome, I don't know why anyone wouldn't want it.

My ultra-dry wit again convinces people I'm being serious...

There's no scenario where you can get your labor costs meaningfully down. The volume's just not there to mass produce.

ahh, sorry. dry wit doesn't convey through text. my bad, I'm pretty dry too, perhaps we off set each other. I was thinking, automated riveters?!? whats next automated mechanics blasphemy!!!
