Ron Hirsch appeared in a Riverside courtroom late Friday on a federal charge of unauthorized flight. His arraignment is scheduled for May 23.
The 60-year-old transient was arrested in Ohio last week after a rabbi recognized him. He is accused of being responsible for a blast that sent a pipe and concrete crashing into a Santa Monica house.
Hirsch has been charged with four felony counts, including possession of a destructive device and explosion with intent to murder.
He faces up to life in prison without the possibility of parole if convicted.
