The Robinson R44 Raven II is a four-seat light utility helicopter
powered by a single fuel-injected, angle-valve, tuned-induction,
Lycoming IO-540 piston engine. The Robinson R44 is built and developed
by the Robinson Helicopter Company in Torrance, California. Design of
the Model R44 began in 1985. The first prototype flew on 31 March 1990
and the second in January 1991. Sales efforts got under way in March
1992 at a base price of 235.000 US-Dollars. FAA Type Certification for
the R44 Astro was achieved on 10 December 1992, and the first Robinson
R44 Astro was delivered in February 1993. In 2000, the R44 Astro was
replaced as the main production model by the hydraulically-assisted R44
Raven. Today the four-seat Model R44 is the world's most popular helicopter with over 6300 delivered to customers all
over the world. The ICAO Aircraft Type Designator for the R44 Raven II helicopters is R44.
