The Phönix-Aviatechnica LKhS-4[1][2] (also transliterated Phoenix-Aviatechnica LKhS-4[3] or Feniks-Aviatechnica LKhS-4;[4] in Cyrillic script Феникс-Авиатехника ЛХС-4) was a 1990s Russian design for a civil utility aircraft of unusual[4] configuration.
Its designation is an acronym of Legkiy Khozyaystvennyy Samolet (Легкий Хозяйственный Самолет) — "light utility aircraft" in Russian.
[4] In addition to general aviation purposes, the LKhS-4's intended use was air-taxi and commuter roles throughout the CIS and it was therefore designed to be able to operate from soft snow or mud.
[8] Construction was to be a light alloy frame, with wing spars of steel tube, covered in panels of composite material.
[6] Production of the LKhS-4 was planned to start in May 1994 at Aviation Repair Factory ARZ-411 in Mineralnye Vody, Russia,[8] but the aircraft would never be completed, much less manufactured.
