MOUNT DIABLO — A small plane crashed into a hillside in Mount Diablo State Park overnight Friday, killing the pilot, authorities said.
The pilot is believed to have been the only person aboard the single-engine Mooney M20 that crashed 2 miles southwest of the Mount Diablo summit, Federal Aviation Administration spokesman Ian Gregor said.
The crash happened “at an unknown time Friday night,” Gregor said, and the plane caught fire after it crashed.
A spokeswoman for California State Parks said one person was killed and no other injuries were reported in the crash.
The San Ramon Valley Fire Protection District was called to Mount Diablo State Park at 2:41 p.m. Saturday for a report of a plane crash, but a dispatcher said the call was canceled when crews were on the way to the scene.
The pilot was flying from Hayward to Lincoln, northeast of Sacramento, and was reported overdue by a family member on Saturday, Gregor said.
Authorities have not released any information about what may have caused the crash. The National Transportation Safety Board will lead an investigation into the crash, along with the FAA, Gregor said.
