Investigations later found that the aircraft was technically sound, most likely the crew had let the passengers into the cockpit in violation of the rules of flight, and were performing wake and tight turns at low altitude for their amusement. Although the aircraft's load was 145 kilograms below the maximum permitted, 23 passengers were irregularly allocated to the 21 seats, while a total of 10 tickets were sold for the flight. After the accident, sightseeing flights over Budapest were banned for a long time.
