Probable cause
Failure of the pilot in Cessna 150, N714RS, to comply with the air traffic control clearance, and failure of both pilots to maintain adequate visual lookout to see-and-avoid each other. Factors related to the accident were: physical impairment of the pilot in the Cessna 172, N128S, due to use of drugs (cannabinoids), and failure of the tower controller to issue a safety advisory.
