Can they?


The biggest mistake made by most human beings: Listening to only half, understanding just a quarter and telling double.

Nope.

They are different, the JT-9D and the CFM56-3.
The chief reason is the difference in size - the CFM56-3 wouldn't fit under the wing of a 732 - it barely fits under a 733/4/5's wing.

Cheers,

Justin

If somebody is willing to spend the money anything is possible.....

But at this point nobody is willing to spend the money.

If there every was a 737-200 reengineering that was proposed I would suspect that they would look at the Tay or the BMR-710 engines as a replacement.

But I don't think the economics will support that work being performed.



OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

Skystar...The B737-200 has JT8D powerplant not JT9D.
The B737-3/4/500s use CFM56-3 engines.
The attach fittings differ.
But I'm sure it can be made compatiable but it would prove expensive.

There was talk back in the early-mid 80s of a 732 reengining program with CFM. Called the 737-250. Around the time the 733 came out and before the 735. There was obviously no airline interest.



Panam, TWA, Ansett, Eastern.......AC next? Might be good for Canada.

No. The biggest reason is that the 732 sits much lower to the ground than the 733-4-5. Because of this, the engine nacelle on the 733/4/5 is flat at the bottom (you've noticed). They had to extend the landing gear to make the plane "taller" even with the flat bottomed engine.

The underbelly/wheel/wingbox area would have to be replaced.

When you get down to it, there isn't much point. Since 737s are still manufactured, just buy a new one. With 727s, it becomes a sensible thing to do.

Hawk21M,

Good point - the -9D is a tad larger than an 8D  Smile

AA737-823....
Could you confirm that the MLG of the 732 is different from the 733/4/5.
I'm talking ONLY of the landing gear.

I'm aware of the 737NGs having a different MLG.
Pls confirm.

skystar....JT9D is used on the B747.

I supposed you suppose that you could mount a pair of JT9D on a 737 but you probably only need one.....

IF you went with two engines would would have to mount them overwing....much like the AN-72

Yep, I know.

It's also on the 767 - old QF762s have them.

Is the MLG of the B732 the same as the B733/4/5.
