The Robinson R22 Beta is a two-seat small rotorcraft powered by a single Lycoming O-360-B2C four-cylinder,
air-cooled piston engine. The R22 was designed by the founder of the Robinson Helicopter Company, Frank Robinson.
Design of the Robinson R22 helicopter began in 1973, and an 85kW (115hp) Lycoming O235 powered prototype flew for
the first time on 28 August 1975. A second followed in early 1977. The FAA certification (TCDS H10WE) was achieved on 16 March
1979 and deliveries started in October of that year. On 12 October 1983, the R22 Alpha model was ceritified. On 5 August 1985, the
R22 Beta model was certified, followed by the R22 Mariner model on 12 September 1985. The R22 Beta had a larger oil cooler and
associated installation changes were made to permit the 131 hp. takeoff rating with the O-320 engine. In 1995, the R22 Beta model,
with the Lycoming O-360-J2A engine installed, entered production. This engine is installed on s/n 2571 and subsequent in production.
R22 Beta II is used as marketing designation for the R22 Beta with O-360-J2A engine installed. Over 4600 Robinson R22 helicopters are
delivered to customers all over the world. The ICAO Aircraft Type Designator for the Robinson R22 Beta is R22.
On 17 August 1995, registration D-HFER was reserved for the 1992-built Robinson R22 Beta c/n 2250 and in February 1996,
the aircraft was registered D-HFER in Germany. The Robinson R22 Beta c/n 2250 was registered before N2349X in the USA with
Heli-Star Aviation Inc., Wilmington, Delaware. When seen at Halle-Oppin Airfield on 27 July 2009, Robinson D-HFER was operated
