The Robinson R44 Raven II is a single-engined light utility helicopter for up to 1 crew and 3 passengers, powered by a carburetted Lycoming
O-540-F1B5 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. The development from the first R44 Astro in 1993, via the R44 Raven I to
the first R44 Raven II delivered in 2002, has been remarkable. For the
pilot the most important difference is the conversion from a carbureted
engine on the Astro to injection and hydraulic controls on the Raven II.
Over 6500 of the four-seat Model R44s are delivered to customers all
over the world. The ICAO Aircraft Type Designator for the Robinon R44 Raven II helicopter is R44.
On 6 February 2012, SP Luftbild, Dattenberg, Germany, started the
monitoring flights over the Netherlands on behalf of Gasunie out of
Teuge airfield near Apeldoorn. The Southern part of the monitoring
flights was done by Robinson R44 Raven II D-HHJS; the Northern part of
the flights was done by Schweizer 269D Model 333 D-HSPZ. Within a few
weeks Schweizer 269D Model 333 D-HSPZ was replaced on these flights by
Robinson R44 Raven II D-HMSH. In May 2014, Robinson R44 Raven II D-HMSH
was replaced by Robinson R44 Raven II PH-ABZ. In 2017, the new contract for the
monitoring flights over the Netherlands on behalf of Gasunie was awarded to Heli and Co.,
which company replaced SP Luftbild on the contract.
In July 2011, Robinson R44 Raven II s/n 13160 was registered first OE-XYE with Heli-Line Hubschrauber Transporte,
Klib, Austria. In January 2012, registration OE-XYE was cancelled as exported to Germany. On 16 February 2012, the
helicopter was registered D-HMSH in Germany with SP Luftbild GmbH, Teuge Airfield, Netherlands. On 13 September 2017,
registration D-HMSH was cancelled as exported to Sweden. On 11 October 2017, the Robinson R44 Raven II was registered
SE-JTM with GCC Capital AB as owner and MJ Bilfinans AB as operator. On 26 November 2020, registration SE-JTM was
cancelled and the next day the helicopter was registered OH-HYI with a privat owner. On 1 May 2013, when seen at vliegveld Hoogeveen,
the 2011-built Robinson R44 Raven II D-HMSH was equipped with pop-out floats for above water operations.
