Officials did not identify the victims of the crash. They said they were investigating the cause.
Officials described the plane as a YAK-52, a Russian-made plane introduced in the 1970s for aeronautic training.
The plane crashed on Western Avenue, a normally busy road lined with strip malls, retail outlets and convenience stores. No other injuries were reported.
Witnesses said shortly after taking off, the plane made a sharp turn and began its descent.
