This helicopter was constructed by McDonnell Douglas back in 1988 and was imported to Sweden by SAAB Helikopter AB the same year. A Swedish registration, SE-HSM, was reserved, but before entering the system the aircraft was exported to Norway and given the registration LN-OCC.
It stayed in Norway for a dozen of years before it returned to Sweden in 2001, this time imported by BN Construction i Motala AB and registered SE-JGB. The aircraft was leased by the Finnish company Helitour for a while and was finally sold to Stockholms Helikoptertjänst AB in early-2003.

The company had two Hughes 300s at that time, and the MD 500 soon proved to be an indispensable addition to the fleet. It was used in all kind of aerial works, including power line inspections, sling-load operations and filming. The machine soon became a rather well-known workhorse among the regional construction companies, but the need for a more powerful sling load lifter became more evident. An Aérospatiale Lama (SE-JNA) was acquired and thereby eased the workload of the busy MD 500. SE-JGB became fully dedicated to power line inspections and she still is today. It's now so busy that it's barely "home" any more. The helicopter can be seen throughout entire Sweden, as well as in neighbouring countries and some parts of northern Europe.
