Those tests feel like an eternity, but it is what it is.

TEI GM Prof. Dr. Mahmut Faruk Akşit:
TS1400 is actually flight-ready with all the tests and similar processes currently being conducted; we are in the third (3rd) and final stage of certification.
If there are no hitches, God willing, we expect to complete the certification process next year.
