Subsequently, it limits itself to operating joy flights, mostly around New South Wales, and offering pilot training services with a fleet of small aircraft.
- The United States Department of Commerce's Aeronautics Branch (predecessor of the Federal Aviation Administration) has issued 48 approved repair station certificates. The certificates entitle repair stations in the United States to repair aircraft of types for which they are adequately equipped, eliminating the previous requirement for them to submit to the Aeronautics Branch detailed drawings of the repairs they make to licensed aircraft and, in some cases, a stress analysis. It had begun issuing the certificates in March 1930. For the first time, a rotary-wing aircraft — the Pitcairn PCA-2 autogiro Miss Champion — takes part in the event.

When the fuel flow to their engine is interrupted they make a forced landing at Bicske, short of their planned destination at Mátyásföld, and arrive by car at Mátyásföld, where thousands of people greet them. The flight is the 15th successful transatlantic flight and the first to fly nonstop from North America so deep into Europe. It covers in 25 hours 20 minutes at a record average speed of . Sponsored by the American-Hungarian Transatlantic Committee to draw attention to what Hungarian Americans view as the injustice of the Treaty of Trianon Hungary signed after its defeat in World War I, the flight also represents the first use of a transatlantic flight for political purposes.
