development
The sports and training aircraft was equipped with a radial engine. The first flight took place on September 15, 1929. A total of seven A48 units were built and registered in Germany. Seven more have been delivered in parts to the Swedish subsidiary AB Flygindustri in Limhamn , where they were converted into the Junkers K 47 .
Unlike the other Junkers aircraft since the Junkers J 2 , smooth sheet metal was used here for the planking of the fuselage. The surfaces and the tail unit were still made of corrugated iron.
