In the papers, Barker's lawyer alleges the former Blink-182 drummer "was hurt and injured in his health, strength and activity, sustaining injuries to his body and shock and injury to his nervous system" in the plane crash, causing Barker "great physical, mental and nervous pain and suffering." The papers also allege Barker has been told his injuries will "result in permanent disability."

Barker filed the lawsuit with Thelma Martin Still, the mother of Barker's associate Charles Still, who died in the Learjet crash along with three other passengers. In the papers, Thelma Still files for damages for "pain and suffering, mental anguish" and "loss of earnings," among other grievances.

The two have filed suit against Clay Lacy Aviation; Inter Travel and Services, Inc; Goodyear Tire and Rubber Company; and Bombadier Inc.
