THE C-182P, N790T, HAD INITIALLY CALLED 8.5 MILES NORTH WEST FOR LANDING, & WAS CLEARED TO ENTER A LEFT DOWNWIND. ABOUT 2 MINUTES LATER, THE PILOT REPORTED HE WAS COMING IN ON THE EAST SIDE OF THE FIELD, WAS CLEARED FOR A RIGHT DOWNWIND, AND ADVISED OF THE OTHER AIRCRAFT IN THE RIGHT TRAFFIC PATTERN.
THE BE-95, N721L, HAD JUST MADE A TOUCH-&-GO AND WAS TURNING TO A DOWNWIND. THE CONTROLLERS REPORTED THAT THE TURN WAS ABOUT A 30-DEGREE CONSTANT TURN WITH NO ROLL-OUT ON THE CROSSWIND LEG. THE AIRCRAFT COLLIDED ABOUT 2 MILES NORTH OF THE AIRPORT. THE AIM STATES, FOR RECOMMENDED VFR TRAFFIC PATTERN OPERATIONS, THAT ARRIVING AIRCRAFT SHOULD ENTER THE PATTERN ABEAM THE MIDPOINT OF THE RUNWAY. THE TOXICOLOGY EXAMINATION OF THE PILOT OF THE C-182P, N790T, DISCLOSED A POSITIVE CANNABINOIDS (MARIJUANA) FINDING, 0.098 MG/L, IN THE URINE SAMPLE.
CAUSE: THE FAILURE OF THE PILOTS OF N790T AND N721L TO SEE AND AVOID EACH OTHER. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: THE PILOT OF THE C-182P, N790T, WAS DISORIENTED AND IMPROPERLY ENTERED THE TRAFFIC PATTERN DUE TO RECENT MARIJUANA USE; THE PILOT OF THE BE-95, N721L, FAILED TO PROPERLY EXECUTE A CROSSWIND LEG IN THE TRAFFIC PATTERN; AND THE LOCAL CONTROLLER FAILED TO VISUALLY MAINTAIN ADEQUATE SEPARATION OF THE TWO AIRCRAFT.
