OY-HAU was stationed in Narsarsuaq and flew for the ICEPATROL, a division under the Danish Meteological Institute surveing the ice around Cape Farewell and assisting ships sailing in the ice.
OY HAU was built in 1973 as aircraft number 8338, initial registration was SE-HEK, and was operated by Greenlandair from 1973-1991, it was then sold to an icelandic operator as TF-HHD. It crashed 14.9.1997 at Kalfeyranfjoll in Hamarsfjordur, Iceland.
This model by Lynn Rogers is in fact a LongRanger, but I haven't found any 206B models with the pontoons that OY-HAU had.
The JetRanger series has become the definitive turbine powered light utility and corporate helicopter of the past three decades.
The JetRanger can trace its lineage back to an unsuccessful contender for a US Army competition for a light observation helicopter, which was won by the Hughes 500. This first Model 206 made its first flight on December 8 1962, while the following civil 206A, powered by a 235kW (317shp) Allison C18A, followed, flying on January 10 1966. Deliveries of the first production JetRangers began late in that same year.
In the early 1970s production switched to the Model 206B JetRanger II with a 300kW (400shp) 250C20 turboshaft, while conversion kits to upgrade earlier As to the new standard were made available. The third major variant of the JetRanger is the 315kW (420shp) 250C20B powered JetRanger III, with first deliveries commencing in late 1977. Once again Bell offered a conversion kit to update earlier JetRangers to the new standard. Other features introduced on the JetRanger III were a larger and improved tail rotor and minor modifications.
