Narrative:
Aircraft was directed to turn left 080 degrees and climb to 13000 ft to intercept musel departure SID. As aircraft climbed to 5000 ft captain observed on TCASII a target at 5500 ft and potential conflict. Socal departure reported traffic. Captain determined a conflict and directed copilot to stop climb. Captain obtained visual contact with conflicting aircraft and TCASII issued a TA followed by an RA 'descend' advisory. Aircraft descended to 4800 ft and captain observed mooney aircraft to pass directly overhead at 5500 ft. Socal was advised and reported clear of conflict. Altitude of mooney was reported to socal aircraft was cleared to climb and continued to 13000 ft.

Title: NMAC BTWN AN MD90 CLBING ON SID DEP AND A MOONEY IN LEVEL FLT AT AN APPROPRIATE VFR ALT.
Narrative: ACFT WAS DIRECTED TO TURN L 080 DEGS AND CLB TO 13000 FT TO INTERCEPT MUSEL DEP SID. AS ACFT CLBED TO 5000 FT CAPT OBSERVED ON TCASII A TARGET AT 5500 FT AND POTENTIAL CONFLICT. SOCAL DEP RPTED TFC. CAPT DETERMINED A CONFLICT AND DIRECTED COPLT TO STOP CLB. CAPT OBTAINED VISUAL CONTACT WITH CONFLICTING ACFT AND TCASII ISSUED A TA FOLLOWED BY AN RA 'DSND' ADVISORY. ACFT DSNDED TO 4800 FT AND CAPT OBSERVED MOONEY ACFT TO PASS DIRECTLY OVERHEAD AT 5500 FT. SOCAL WAS ADVISED AND RPTED CLR OF CONFLICT. ALT OF MOONEY WAS RPTED TO SOCAL ACFT WAS CLRED TO CLB AND CONTINUED TO 13000 FT.
