Narrative:

Small transport X was sebnd at 9000' assigned heading 140 degree. Small transport Y nwbnd at 11000' landing luk. Small transport Y was assigned present heading for traffic and cleared to 4000'. Aircraft were 40 mi apart when clrncs were issued. Controller became busy with second situation and could not monitor this situation. Small transport Y could have been issued a better rate of descent through 8000'.

Title: LESS THAN STANDARD SEPARATION OCCURRED BETWEEN AN ARRIVING ACFT AND AN ENROUTE ACFT AT 9000'.

Narrative: SMT X WAS SEBND AT 9000' ASSIGNED HDG 140 DEG. SMT Y NWBND AT 11000' LNDG LUK. SMT Y WAS ASSIGNED PRESENT HDG FOR TFC AND CLRED TO 4000'. ACFT WERE 40 MI APART WHEN CLRNCS WERE ISSUED. CTLR BECAME BUSY WITH SEC SITUATION AND COULD NOT MONITOR THIS SITUATION. SMT Y COULD HAVE BEEN ISSUED A BETTER RATE OF DSNT THROUGH 8000'.
