Proto 2 was a training biplane manufactured at the Fabrica de avioane Astra in Arad in 1924.[1][2]
Following the accident of Ioan Sava, a new variant of the Proto 1 was created, called the Proto 2. The airplane kept the original design, but as a safety measure, the structure of the wings was strengthened by increasing the section of the spars and adding another pair of interplane struts.[2]
