The company was founded in 1954 by the mountain-aviatorGunnar Andersson. At first, operations were solely by seaplanes. The company also ran cabins in the mountains for mainly fishing tourists and grouse hunters. Later these were sold off and rotor-wing aircraft took over entirely.
Andersson died in a plane crash in 1974. Later his daughter Siw A. Grinde took over as CEO in 1981 and ran the company until his granddaughter Sara Grinde took over as CEO in 2007. The company ceased all operations in 2019.
