Having developed the all-metal single-seat Partenavia Aeroscooter earlier, Mario de Bernardi sought to improve the design as the two-seat M.d.B.
The partial welded steel tube fuselage uses aluminum skins.
In April 1959, De Bernardi died of a heart attack after flying a demonstration of the prototype at Rome Urbe Airport.
[1] An example is on display at Museo Aeronautico Caproni di Taledo, Milano.
[2] The daughter of De Bernardi is offering plans for a modernized version of the Aeroscooter using a Rotax 912UL engine to be flown under Italian microlight category.
