The celebrity DJ, whose real name is Adam Goldstein, is suing the plane's manufacturer, Learjet, and several other companies.
Goldstein is seeking $10 million for medical expenses, lost earnings, profits and economic damages and another $10 million related to non-economic losses, such as mental and physical pain, according to a document filed Friday.
A jury will decide any damage award if the case goes to trial.
Several of the companies sued last year by Goldstein and fellow crash survivor Travis Barker are seeking a trial delay until after a government investigation of the Sept. 19 crash is complete.
A lawyer for Learjet did not immediately return a phone message on Monday afternoon.
