Primary finding
Probable cause
Inadequate visual lookout by the plots of both airplanes, which resulted in their failure to see-and-avoid conflicting traffic, and failure of the relieving controllers to use the radar display to identify and sequence an airplane entering the pattern. Factors related to the accident were: an inadequate briefing by the off-going controller, and inaccurate position reports by the pilot-in-command of n5279r.
