The single-engine aircraft went down shortly after 10 a.m. at the Newhall Avenue exit in Newhall. Flames ignited after the plane struck a tree, according to a California Highway Patrol log.
Witnesses' video from the scene showed a large plume of black smoke rising above the mangled wreckage in a grassy area near the off-ramp.
