In early 1946 the work resumed, also slowed down by British resistance to delivering the needed engines, so the aircraft was completed in June 1946 and the first flight took place on August 27, 1948.

Although flight testing went well, the project was abandoned as a result of financial problems, anticipated competition from American airliners in the postwar market, and pressure (under the Marshall Plan) to close down Breda's aeronautical section.

Despite orders in 1950 from India, Argentina and Persia, only the prototype was built, allegedly also due to pressure from the allies for Italy to refrain from competing in civilian aircraft manufacture after the war.

[citation needed] On 27 August 1948 the Bz 308 made its maiden flight in front of civil and military authorities, politicians and the Italian President.

The prototype, which passed to the Italian Air Force in 1950, was used to fly between Rome and Mogadishu until 21 February 1954, when it was damaged beyond repair by a collision with a cement truck, and was abandoned in a field in Somalia before being broken up.
