Narrative:

While climbing to 17500 ft MSL to drop 12 skydivers, I contacted slc approach to obtain VFR advisories. The controller gave me a beacon code at about 10500 ft in the climb. He was busy with IFR arrs into slc TCA. I was climbing VFR and about ready to start 'jump run' nwbound over cedar valley airport when I was issued the following advisory: 'TA, traffic 9 O'clock, immediate descent.' I began a gradual (500-1000 FPM) descent initially and looked for traffic. A widebody transport was in a descending right turn approaching me from 10-11 O'clock at approximately the same altitude. I immediately took maximum (full control deflection) evasive action. I descended as rapidly as possible. The widebody transport was in a 30 degree plus right bank and descending. We missed by less than 200 ft horizontally and vertically. I had been scanning for traffic the entire flight 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 controller'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.

Title: 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.
