The suit claims that these requests for additional instruction were ignored and that the dangerous flight only took place because filming was behind schedule and things were rushed between filming locations.
Ultimately, it was the lack of supervision over the flight by the production company that resulted in the crash.
According to a press release sent out announcing the suit.
Carlos Burl made the producers of American Made aware that he had limited experience in flying an aircraft like the Aerostar, and would require additional training in order to do so safely.
