Probable cause
Failure of the Cessna 150 pilot to see-and-avoid the Cessna 152 (inadequate visual lookout), and failure of the tower controller to provide adequate service. Factors related to the accident were: high traffic density, which resulted in frequency congestion, and failure of the Cessna 150 pilot to follow established traffic pattern procedures.
