TAI offered the Hurkus with co-production. It's powered by the PT6 which also powers the AW139 and Bell-412EP and for which PAC spent money raising an MRO facility.
If they wanted to push a COIN platform, they could have partnered with TAI when the Hurkus-C was drawn up and jointly sold that for $20 m a pop (still cheaper than the Super Tucano) - accruing even 25% of a contract's value would have returned $5 m per plane to PAC, which is the value of multiple Super Mushshak.
With Turkey's clout, they might have seen penetration in markets that are today buying IOMAX Archangels and Air Tractors - the cumulative life-cycle value of those markets is $1bn.
When I floated the idea of investing in the Hurkus-C to retired officers, I got a lecture on how slow moving planes are a liability, why everyone wants fast jets, etc, etc. ...and here we are today arming an even slower plane with less.
