A man was killed Sunday afternoon when the plane he was flying crashed onto BART's Hayward-area tracks.

According to Hayward Fire Department Captain Don Nichelson, calls reporting that a plane had crashed on the BART tracks then burst into flames started rolling in at around noon Sunday.

The Chron reports that "the plane, a twin-engine Piper PA23, went down at 12:05 pm at 1001 Whipple Road and Railroad Avenue, near Hayward’s border with Union City and about 4 miles east of Hayward Executive Airport."

According to an email statement sent by BART Sunday, the aircraft struck "the transfer tracks near Hayward Yard."

"We can confirm the crash started a fire," BART write in their statement. "There is a confirmed fatality on the plane. No BART injuries are reported."

Following the crash, BART halted all service south of the South Hayward Station and closed their Union City and the Fremont stations. Both were reopened and service was restored by 2 p.m.

According to Federal Aviation Administration spokesperson Ian Gregor, the pilot was the only person onboard the plane at the time of the crash. As of publication time, he had not been publicly identified.

Both the FAA and, Gregor says, the National Transportation Safety Board will work to determine the cause of the crash. As of Monday morning, those investigations were ongoing and further information was not available for public release.
