Kyiv-based aircraft producer Aviant has signed an agreement with Kazan aviation plant to jointly produce the new Russian passenger plane Tu-334, according to the Russian officials. Inna Perepelytsya: After the An-148 project, Tu-334 is the second joint Russian/Ukrainian project for construction of a new regional passenger jet.
