It is indeed the Malmo MFI-10B Vipan.
AB Malmö Flygindustri (MFI) first commercial success - the small MFI-9 - took to the air in 1961. The same year the MFI-10 ”Vipan” (”the Lapwing”) began its flying trials. If the MFI-9 became a success, the MFI-10 unfortunately became the opposite.
MFI started in 1955 to design a larger aircraft than the MFI-9. This new four-seat aircraft would be suitable for the Army’s need of fire direction and liaison. It would also be possible to use the aircraft as a flying ambulance and as a trainer, tug and for photographing. And, not least it would be in the market as a pure private aircraft.
The Vipan was a high-winged design to give good visibility. Its tail-wheel made it possible to use unprepared landing strips and it could take off in only 180 metres.
Three Vipan were built. The two last were ordered by the Army for evaluation. As these two had a more powerful engine (Lycoming 0-360- A1A of 180 hp) than the prototype, they were called MFI-10B and got the Army designation FPL 54. They were delivered to the Army in 1963.Their registration numbers were 54001 and 54002, later changed to 54381 and 54382.
