Narrative:

I was not actually working during the event. I am the operation supervisor of the employee who had the event. I worked the day shift on the day of and the employee worked the night shift. The following day I became aware of the event and conducted a performance discussion with him. The employee and I reviewed the event and discussed factors that contributed to [it] and mitigations for the future. The employee was very engaged and receptive. The employee's normal performance is excellent. After reviewing the event the controller did not violate any rules and never lost separation. Aircraft X was cleared for a visual approach following traffic and switched to the tower. The aircraft was turning to final from the left base when he went through final and conflicted with an aircraft on a parallel runway. We discussed the dangers of using the same altitude on opposing bases but I felt that was not a contributing factor in this instance. The controller also issued a 30 degree intercept in a timely manner. It was the pilot's error of going through final that caused the event. I honestly believe that the 7110.65; 7-4-4; is responsible for placing these two aircraft in an unsafe proximity. I have had to have way too many performance discussions with employees about this very same scenario of vectoring aircraft to parallel runways during visual approaches. The procedure does not prevent aircraft from being vectored to the same point on the finals at the same altitude as long as a controller issues the visual approach to only one aircraft. It also only gives best practices and not direction on how to keep the planes separated. I see far too many close calls where planes don't collide from pure luck. The 7110.65; 7-4-4 needs to be changed to require aircraft to have standard separation until established inbound on the final approach course. Until then we will continue to have these very unsafe events at airports around the NAS.

Title: ATC Supervisor reported a Controller complied with the rules and cleared an aircraft for a visual approach which subsequently conflicted with parallel runway traffic by flying through the final approach course.
