AN SMT CARRYING SKYDIVERS HAD AN NMAC WITH A WDB.

Narrative

WHILE CLBING TO 17500 FT MSL TO DROP 12 SKYDIVERS; I CONTACTED SLC APCH TO OBTAIN VFR ADVISORIES. THE CTLR GAVE ME A BEACON CODE AT ABOUT 10500 FT IN THE CLB. HE WAS BUSY WITH IFR ARRS INTO SLC TCA. I WAS CLBING VFR AND ABOUT READY TO START 'JUMP RUN' NWBOUND OVER CEDAR VALLEY ARPT WHEN I WAS ISSUED THE FOLLOWING ADVISORY: 'TA; TFC 9 O'CLOCK; IMMEDIATE DSCNT.' I BEGAN A GRADUAL (500-1000 FPM) DSCNT INITIALLY AND LOOKED FOR TFC. A WDB WAS IN A DSNDING R TURN APCHING ME FROM 10-11 O'CLOCK AT APPROX THE SAME ALT. I IMMEDIATELY TOOK MAX (FULL CTL DEFLECTION) EVASIVE ACTION. I DSNDED AS RAPIDLY AS POSSIBLE. THE WDB WAS IN A 30 DEG PLUS R BANK AND DSNDING. WE MISSED BY LESS THAN 200 FT HORIZLY AND VERTICALLY. I HAD BEEN SCANNING FOR TFC THE ENTIRE FLT AND JUST FINISHED A SCAN OF THE 12-4 O'CLOCK AREA. I FEEL THE CLOSURE RATE AND ANGLE OF INTERCEPT CONTRIBUTED TO THIS NEAR COLLISION. IN ADDITION; THE CTLR'S INABILITY TO OFFER A MORE TIMELY ADVISORY WAS A CONTRIBUTING FACTOR. BOTTOM LINE: WE WERE LUCKY AND I WILL SPEND MORE TIME 'OUTSIDE THE COCKPIT' AND NOT TAKE COMPLACENCY INTO ANY RADAR ENVIRONMENT.
