I just heard from someone that some company is talking about refitting the old Jetstreams with jet engines. Has anyone heard anything about this? I was wondering how the heck that would work I mean that acft isnt built for it. But hmmm a 19 seat Regional Jet....that could be neat  Nuts

AW&ST reported on this potential STC about 2 months ago, using Williams FJ44s.

Why is it "Never Gonna Happen"?

1. Why? The J31/41 are good aircraft without jets.
2. Cost. It would be very expensive to convert them into jets, and would tend to have higher fuel burn.
3. Difficulty. This hasn't been done before, so a lot of time would be needed to carry out the conversion, then lots of test flight and recertification.
4. The aircraft wasn't designed for jets, the location of jets, the stresses caused by jets, the electronics and fuel control of jets or the speed the aircraft would have. Therefore, extensive modification on nearly all of the aircraft's systems would be needed in order to install turbofans. The J31/41 wasn't designed to cruise at 400kts, so it's not going to cruise significantly faster than it already is.

For a few 19-seaters, what's the point???

May 21 issue, btw...

1. There is currently no 19 seat regional jet in operation. Ten years ago, there were no 32-37-40-42-50-70 regional jets in operation. Most Beech 1900s are being parked, eliminating service to small communities. Could a 19 seat RJ bring customers back?

2. Of course there is a cost issue. Potential operators have to determine if it is feasible to undertake.

3. You ever hear of the DO328 Jet? Reference #2 above.

4. Ref 3 above. The current service ceiling of the J31/32 is, I believe, 25000 feet, so there are certainly some fatigue and speed issues. But it has been done before, and done successfully, and if someone decides to fund it, it could certainly happen.

Cheers-

Ok, no one is going to fund it. The 328JET isn't in the same league as the J31/41. The point is, with all the modifications, certifications, testing etc. it'd be cheaper to buy a new 328JET. A 19 seat RJ would be handy, but forget about converting current (and btw, out of production) regional props.

This would be very interesting, I for one can see this happening as a test at the minimum...even if it doesnt go beyond the test phase it would be interesting...

The 19 pax market is a dead market. A Junkstream with jets? Just stop. Only a fool would waste money on that airframe.

Again, Williams should fire their R&D folks and just consult naysayers and "experts" on the net.

Someone brings up an interesting topic on a TECHNical Forum (which makes it worthy of discussion), and the flat out answer is:

"Not gonna Happen..."

-or-

"No one will Fund it"

That sounds a lot like the A3xx debate...before it became the A380.

Cheers-
