Jabiru

TYPE : Side-by-side ultralight/kitbuilt.

COUNTRY OF ORIGIN: Australia

PROGRAMME : Design of original Jabiru LSA, started 1987; prototype (first of two, VH-JCX and VH-JQX) made first flight August 1989; first customer delivery April 1991; factory-built version certified to CAO 101 Pt 55 on 1 October 1991; 20 built with KFM engine before change to 44.7 kW (60 hp) Jabiru 1600 flat-four, many of these subsequently re-engined;

kitplane construction certification achieved in Australia, New Zealand, South Korea, UK and USA by early 1997; marketed in US as amateur-built kit, achieving FAR Pt 21.191 (g) certification on 8 February 1996 (as well as Australian CAO 19 equivalent); marketing office opened at Aiken, South Carolina, in anticipation of substantial US sales of at least 100 per year but later closed in favour of network of dealerships. Total of 54 built with 1600 engine between April 1993 and March 1996. More powerful ST version introduced in 1994.

Joint venture announced in 1998 with CDE Aviation Company of Sri Lanka, subsidiary of Lionair, to establish Jabiru Asia for manufacture of Jabiru ST3 for Asian markets, especially India. Jabiru factory at Koggala, in southern Sri Lanka; intended to have production capacity for 40 aircraft per year, using engines and avionics imported from Australia, and airframes manufactured locally. Nothing further had been beard of this by 2003.
