TEHACHAPI, Calif. (AP) - Authorities say two people died when their single-engine plane crashed in Kern County, sparking a large grass fire.

Kern County fire department spokesman Sean Collins says the accident occurred about 1:30 p.m. just west of Tehachapi when the plane crashed on the roadway of Old Town Road.

The plane ignited a blaze that grew to about 2.5 acres before it was extinguished by some 40 firefighters.

Collins says no further details were immediately available.

The Federal Aviation Administration and the National transportation Safety Board have been notified.
