Narrative:

Training on both radar arrival positions; H and V. Aircraft Y being vectored by H trainee for visual approach to runway 4R; handed off to V trainee approximately 5NM northeast of hnl. V trainee turns aircraft Y to a 220 heading; downwind; and descends him to 060. Air carrier X departs runway 8R; turning to a 155 heading; climbing to 050. I tell V trainee we're stopping at 050. V trainer and trainee say they're stopping aircraft Y at 060. Their courses cross approximately 5 NM south-southeast of hnl. V trainee then descends aircraft Y to 015; then goes back and stops him at 030 for inbound traffic. Meanwhile; H trainee turns air carrier X to a 260 heading. V trainer sees air carrier X turning and asks what he's doing. I tell him he's turning to a 260 heading stopping at 050. V trainer stops aircraft Y at 050. Aircraft Y asks for the altitude again and V trainer says turn right heading 300. V trainer then issues aircraft Y a traffic alert and tells him again to turn right heading 300. Meanwhile; you hear a couple clicks on H frequency. You hear H trainee say ' air carrier X' twice; but give no instructions. H trainee gives traffic call to air carrier X and he reports gulfstream in sight at which point H trainee tells air carrier X to maintain visual separation; however separation was already lost. After both aircraft are separated air carrier X uses the words 'traffic avoiding' or 'traffic avoidance' and advises heading 260 maintaining 050. Air carrier X never stated that he was responding to a TCAS RA; however; he did climb to about 055 or 056 when H trainee was issuing traffic. Along with his wording of the 'traffic avoiding' and climb I believe he was responding to a TCAS-RA; but did not advise of it. Recommendation; H; west and V personnel were assuming each was doing something different. H was under the impression that V was going to keep aircraft Y above air carrier X as he turned westbound. That is what I thought H was going to do as well; even though that was not a wise decision. Aircraft Y would get screwed due to having to fly a 20 mile downwind while air carrier X got out of the way as he flew westbound. V thought H was going to leave air carrier X on his initial departure heading of 155 and continue his climb after their courses had crossed; which is why he descended aircraft Y when he did. I made mention that something had to be done with air carrier X; a turn or descent; something; but I was not forceful enough. The H trainee had no idea of what to do to ensure they did not hit. Separation was lost; there was nothing that could salvage that situation; however; after acknowledging that the situation was turning from bad to worse; the trainee couldn't say anything and was clearly shaken after the incident. I should have told him what to say since the H trainer didn't say anything. In the H trainee's defense; he did ask his trainer repeatedly what he should say. I should also have told V when air carrier X was given the 260 heading; but more importantly I should have noticed aircraft Y descending and told the H trainee not to turn air carrier X; instead leave him on his 155 heading. In short; I should have told each person to wake up and pry these two airplanes apart; and been forceful about it; rather than waiting for each trainee and trainer to get it done.

Title: HCF coordinator described operational error event involving two trainees on both arrival positions; the reporter noting neither of the trainee's knew what to say and both instructors failed to provide guidance; adding he/she should have intervened sooner and been more forceful about the resolving the developing conflict.
