A Saturday night plane crash at the San Rafael Airport left one person dead and another in critical condition, said deputies.

According to initial investigations from the Marin County Sheriff's Office, two passengers were on board a small aircraft when the plane went down in a marsh at the east end of a runway.

One person was pronounced dead at the scene, and the other was transported to a local hospital in critical condition.

The plane's tail fin also struck electrical lines and prompted a power outage in the area at 10:02 p.m., according to a PG&E spokesperson. About 1,887 customers were affected by the blackout.

Deputies said PG&E turned off the lines so the San Rafael Fire Department could handle the extrication of the passengers.

As of Sunday morning, deputies are waiting for the arrival of the National Transportation Safety Board, who will take on the crash investigation.
