Narrative:
I was captain of a DHC6 and had just finished dropping skydivers over E60 airport from 14500 ft MSL. I was under radar advisories by ZAB. I had advised center that my skydivers were away and was descending into eloy (E60). Center advised me that there was IFR traffic 3 mi east of the airport wbound at 10000 ft. Center advised the other aircraft of my position, at which time the other aircraft stated that he had me 'in sight dropping like a rock.' I was descending within 2 NM of E60 and did not have a visual with the other aircraft until I passed through his altitude at 10000 ft. I never crossed through the aircraft's flight path but did turn as did he. Perhaps this could have been avoided by both pilots seeing and avoiding other traffic. Also, center should divert IFR traffic around known skydiving operations.

Title: DHC6 FLC TURNS AFTER DROPPING SKYDIVERS TO ASSURE SEPARATION WITH IFR TFC DURING A VFR DSCNT. BOTH ACFT WERE GIVEN TA'S BY ARTCC RADAR CTLR.
Narrative: I WAS CAPT OF A DHC6 AND HAD JUST FINISHED DROPPING SKYDIVERS OVER E60 ARPT FROM 14500 FT MSL. I WAS UNDER RADAR ADVISORIES BY ZAB. I HAD ADVISED CTR THAT MY SKYDIVERS WERE AWAY AND WAS DSNDING INTO ELOY (E60). CTR ADVISED ME THAT THERE WAS IFR TFC 3 MI E OF THE ARPT WBOUND AT 10000 FT. CTR ADVISED THE OTHER ACFT OF MY POS, AT WHICH TIME THE OTHER ACFT STATED THAT HE HAD ME 'IN SIGHT DROPPING LIKE A ROCK.' I WAS DSNDING WITHIN 2 NM OF E60 AND DID NOT HAVE A VISUAL WITH THE OTHER ACFT UNTIL I PASSED THROUGH HIS ALT AT 10000 FT. I NEVER CROSSED THROUGH THE ACFT'S FLT PATH BUT DID TURN AS DID HE. PERHAPS THIS COULD HAVE BEEN AVOIDED BY BOTH PLTS SEEING AND AVOIDING OTHER TFC. ALSO, CTR SHOULD DIVERT IFR TFC AROUND KNOWN SKYDIVING OPS.
