Two airport workers were able to prevent Sein from going onto the taxiway, and he was taken to a hospital for evaluation before being booked into the Mecklenburg County jail.
Sein got up out of his seat after the fasten-seatbelt sign was illuminated.
Sein is accused of biting the flight attendant's hand before opening the galley service door and jumping onto the tarmac. He "tried to bite" the crew member trying to get him back in his seat, according to the affidavit, and went looking for another door to get off the plane.
While two passengers tried to intervene he managed to open the aircraft door and jump out of the plane onto the tarmac below. He was transported to Carolinas Medical Center for treatment and was arrested. After the incident, the plane returned to the gate and was rescreened while passengers waited in the terminal, American said.
Sein jumped from the plane onto an active ramp, the complaint said.
The flight, scheduled to depart at 9:40 a.m., took off almost two hours behind schedule. According to federal affidavit filed with the case, Sein spoke little or no English.
Sein is charged with interfering with flight crew and attendants and appeared in North Carolina federal court Friday.
Federal authorities say Sein flew into Newark from overseas and then to Charlotte for this flight to New Bern. But U.S. air marshals say Sein seemed to understand the commands of the flight attendant as well as the safety requirements of passengers on commercial flights.
