PT6A is a 50+ years old commercial engine, You can buy it online, overhauled/second hand or as a scrap and overhaul it yourself. There are 50.000+ engines produced. Just like Rotax engine, this wont stop production. But it might cost a couple thousand dollar more than direct purchase.How to export them without engine? Did Canada not put a total embargo?
If push comes to shove, there is Motor Sich AI24 engine with 1650hp shaft power turbo prop engine.PT6A is a 50+ years old commercial engine, You can buy it online, overhauled/second hand or as a scrap and overhaul it yourself.

Does the airplane don't need structurel changes? I mean designed for one purpose engine, just like that you can swap engine>?
You would simply re-certify the plane with the new engine if the engine has its own certification.Nope! You cannot just change the engine. Technically possible of course but you would not have it EASA certified
Yes but the plane would have a re-certification, everything is possible but takes again time. Maybe a year?You would simply re-certify the plane with the new engine if the engine has its own certification.
Depending on what kind of operations the customer will conduct they can even operate the plane uncertified for a period of time based on TAI's word of reliability. If the country will only operate it in its own airspace they can do it with no certification at all. This is possible in every country per se. Yet even TAI will conduct many test spanning over many months for its own peace of mind.Yes but the plane would have a re-certification, everything is possible but takes again time. Maybe a year?
EASA certification was for a possible civilian variant i think.but you would not have it EASA certified
Didn’t Kotil say that they have to rebuild the whole plane again anyway? Airforce and Army didn’t like the aluminium alloy body. They want composite materials. so the plane is being rebuilt. So they might as well use a new engine that we can have access to freely.Unfortunately not possible, everything has been designed for that size and weight. You have to create another plane from scratch for another engine, PT6A-68 weights 270k while AI-24 is 600 kg. Size, fuel consumption, weight etc. everything is different. Only sustainable solution is to design a similar engine by using TS1400 core. For comparison CTS800-4A weights 163kg without shaft / gearbox and 185 with shaft, so TS1400 would better suit the role in couple of years..
Of course there are always alternatives, domestic one would not be ready to fly at least 2 more years but PT6A has been optimized and widely available engine. Plane would not give same performance without it, plane is designed for that even 1kg change would alter balance of the aircraft. If I understand correctly rebuilding process is just replacing aluminium body parts with composite ones. It would be lighter and easy to maintain. You develop and test a plane for 10 years with every length weight etc calculated, optimized and that matures in time and if you change size of engine placement everything just becomes obsolete. Even if they put 300 kg engine instead of 270 kg, then balance of plane changes. Every test has to be done againDidn’t Kotil say that they have to rebuild the whole plane again anyway?

AI24’s weight is 600kg. That is too heavy for that plane. you are right. But it was just a suggestion. There is a MS14 engine with 1500 hp power and 300kg weight. So there are new engines that can be considered.
Yes! Everything will change. Even if they used the same engine they would have needed to redesign the lot. Because the weight of composite materials will be different to aluminium ones.Of course there are always alternatives, domestic one would not be ready to fly at least 2 more years but PT6A has been optimized and widely available engine.

Pratt&Whitney is based on the U.S but PT6s are manufactured by the P&W Canada, based on Canada. They might try to go around by having them manufactured in the U.S, maybe.How to export them without engine? Did Canada not put a total embargo?
I don't know for sure, as of my understanding system works like this; You order what you want and if senate doesn't block the order in 15 days your order passes. President can also pause the prosses to investigate the order himself.Ain't US embargoing too?
