Design and development

In 1964, an agreement was signed between Poland and the Soviet Union assigning production of the Mil Mi-2 twin-engined light helicopter exclusively to the WSK PZL-Świdnik factory at Świdnik, Poland.[1]

Work on a significantly redesigned version of the Mi-2 started in 1977.[2] PZL decided to develop, in conjunction with the American aero-engine company Allison, a re-engined version for export for western markets, the Kania or Kitty Hawk.[1] The changes include a modified fuselage with more pointed nose, new engines (Allison Model 250-C20B turboshaft engines) each rated at 313 kW (420 hp), new composite rotors blades, and new western avionics. The first prototype, utilizing a modified Mi-2 airframe, was flown on 3 June 1979.[3] Two prototypes were made and two pre-series machines. Tests conducted during the early 1980s led to certification according to FAR-29, in February 1986.[2]

The prototype SP-SSC took part in the 5th Helicopter World Championships in Castle Ashby in 1986.[2] Production started that year in limited quantity, in the PZL Świdnik factory. The helicopter was intended to be a replacement of the Mi-2, more economical, comfortable and offering better performance, and it compared quite favourably with Western counterparts. It did not become popular, however, partly due to problems with certification and a weak promotion in Western countries, and reluctance to spend convertible currency for imported parts in Eastern Bloc countries in the 1980s. Only 19 were built until 2006, including prototypes.[4] It isn't currently offered by PZL-Świdnik.[5]

The main user is the Polish Border Guard, with 7 helicopters (not concurrently). The Polish Police used two helicopters.[4] Three Polish Kanias were employed in air service in Sierra Leone in 1987–1990.[6] In 2007, Świdnik offered 6 armed Kanias for Philippine Air Force, but lost in competition[7] (finally, after cancelling a procedure, PZL W-3 Sokół was chosen).
