Looks like the long mentioned Embraer E-Jet partnership with TAI might also come together with a THY buy of E-Jets if it happens. I don't really see how that really would work unless it's for AJet, but let's see.
"What makes this matter significant is not just Turkish Airlines’ search for aircraft. During my time in Brazil, I learned that a delegation from Turkey—comprising representatives from the Ministry of Industry and Technology and TUSAŞ—was also in contact with Embraer. I even had the opportunity to speak with some of the individuals on the delegation. The discussions are not limited to aircraft sales.
Topics such as production, technology sharing, joint engineering efforts, maintenance activities, and industrial cooperation are also on the table. The most significant issue that caught my attention, however, was the possibility of jointly producing a civilian passenger aircraft. Although this is still in the early stages, this possibility is extremely important in terms of Turkey’s civil aviation goals. This is because Embraer and TUSAŞ possess two distinct strengths that complement each other.
Embraer is one of the world’s most experienced manufacturers in the civil passenger aircraft and business jet sectors. TUSAŞ, on the other hand, has established significant engineering capabilities through projects such as KAAN, HÜRJET, ANKA, AKSUNGUR, GÖKBEY, and space initiatives. Therefore, the two companies’ search for common ground is no coincidence."
