Descripción:
Approaching St. Louis runway 17, the Ozark DC-9 collided with Cessna 150F N8669G (operated by Interstate Airmotive) at 1100 feet msl. The Cessna crashed and the DC-9 landed safely.

PROBABLE CAUSE: "The combination of: the inadequacy of current VFR separation standards in controlled airspace, the crew of the DC-9 not sighting the Cessna in time to avoid it, the absence of VFR traffic pattern procedures to enhance an orderly flow of landing aircraft, the local controller not assuring that important landing information issued to the Cessna was received and understood under the circumstances of a heavy traffic situation without radar assistance, and the Cessna crew's deviation from their traffic pattern instructions and/or their continuation to a critical point in the traffic pattern without informing the local controllerof the progress of the flight."
