Air rescue crews are searching Northern California mountains for a single-engine plane reported missing after it failed to land as scheduled.
The Santa Rosa Press Democrat newspaper reports the Socata TB-20 Trinidad with two people aboard left the Truckee-Tahoe Airport near the Nevada border Monday afternoon.
It was expected to land about 180 miles away at the Petaluma Municipal Airport north of San Francisco.
Family members reported the plane missing and a search was started by the Civil Air Patrol, the all-volunteer civilian auxiliary of the U.S. Air Force.
Officials say the four-seat aircraft is equipped with an emergency locater transmitter but crews have not picked up any signal.
