Narrative:

I was training an ATP applicant and we just departed off chino airport en route to pdz VOR, talking to socal approach at 3000 ft. At pdz socal informed us that we had a traffic alert, 'traffic at 10 O'clock less than 1 mi same altitude.' the traffic was actually at 2 O'clock and passed directly underneath us. It was a coast guard helicopter also talking to socal. Both of us were doing practice approachs into chino airport. This occurrence could have been avoided if approach control warned us of the traffic sooner. They were extremely busy but they need to tell aircraft of each others' position when they are in close proximity to each other, as soon as possible. Approach controller could have also given us a vector to fly to avoid close contact with the helicopter. I deal with socal approach everyday and most of the time they point out any traffic or give you a vector to fly to avoid it. Hopefully this will not happen again.

Title: NMAC WHEN ROTARY WINGED TFC Y, PASSES UNDER AN SMA, ACFT X DURING RADAR TA SVC. CTLR GAVE WRONG DIRECTION CALL ON TFC, ACFT Y.

Narrative: I WAS TRAINING AN ATP APPLICANT AND WE JUST DEPARTED OFF CHINO ARPT ENRTE TO PDZ VOR, TALKING TO SOCAL APCH AT 3000 FT. AT PDZ SOCAL INFORMED US THAT WE HAD A TFC ALERT, 'TFC AT 10 O'CLOCK LESS THAN 1 MI SAME ALT.' THE TFC WAS ACTUALLY AT 2 O'CLOCK AND PASSED DIRECTLY UNDERNEATH US. IT WAS A COAST GUARD HELI ALSO TALKING TO SOCAL. BOTH OF US WERE DOING PRACTICE APCHS INTO CHINO ARPT. THIS OCCURRENCE COULD HAVE BEEN AVOIDED IF APCH CTL WARNED US OF THE TFC SOONER. THEY WERE EXTREMELY BUSY BUT THEY NEED TO TELL ACFT OF EACH OTHERS' POS WHEN THEY ARE IN CLOSE PROX TO EACH OTHER, AS SOON AS POSSIBLE. APCH CTLR COULD HAVE ALSO GIVEN US A VECTOR TO FLY TO AVOID CLOSE CONTACT WITH THE HELI. I DEAL WITH SOCAL APCH EVERYDAY AND MOST OF THE TIME THEY POINT OUT ANY TFC OR GIVE YOU A VECTOR TO FLY TO AVOID IT. HOPEFULLY THIS WILL NOT HAPPEN AGAIN.
