Russian Helicopters is redeveloping the Kazan Ansat light twin with conventional flight controls, as opposed to the fly-by-wire (FBW) system with which it has been flying thus far. Kazan Helicopters has performed the first demonstration flight with a hydro-mechanical flight control system.

The testing program, which involves two prototypes for flight and ground tests, started last year. The manufacturer has filed an application with the Interstate Aviation Committee’s Air Registry for additional type certification, which it expects to achieve in the second half of this year.
