A TWIN CESSNA COLLIDED WITH A SINGLE ENGINE CESSNA FROM THE SINGLE ENGINE CESSNA'S 7 O'CLOCK POSITION. THE SINGLE ENGINE CESSNA CRASHED AND THE TWIN CESSNA LANDED WITHOUT FURTHER INCIDENT. BOTH AIRPLANES WERE CONDUCTING VISUAL FLIGHT RULES PERSONAL FLIGHTS TO VAN NUYS, CA. THE SINGLE ENGINE CESSNA 172 WAS RECEIVING TRAFFIC ADVISORIES FROM BURBANK TRACON. THE TWIN ENGINE CESSNA HAD DEPARTED FULLERTON AND WAS FLYING A CIRCUITOUS ROUTE TO VAN NUYS IN ORDER TO AVOID THE AIRPORT RADAR SERVICE AREA. THE SINGLE ENGINE CESSNA WAS TRANSPONDER EQUIPPED BUT WITHOUT MODE C CAPABILITY. THE TWIN ENGINE CESSNA WAS EQUIPPED WITH, AND USING, A TRANSPONDER WITH MODE C CAPABILITY.

CONTRIBUTING TO THIS ACCIDENT WAS THE CONTROLLER'S FAILURE TO OBSERVE THE FASTER MOVING AIRPLANE APPROACHING THE SINGLE ENGINE CESSNA FROM THE REAR.
