Narrative:
The first officer and I were busy briefing the approach for dayton, and setting up our navigational equipment, when approach control directed a descent from 12000 ft to 10000 ft. The new altitude was set in and pointed to by both pilots, but at that moment a flight attendant came into the cockpit with some request or problem. She stayed briefly and left, after which I resumed what I was doing, which was setting up radios and briefing the approach. I didn't realize I had not started the descent to 10000 ft. Moments later, the approach controller rather excitedly asked if we had yet started out of 12000 ft for 10000 ft, while directing some other aircraft to turn 'immediately.'

Title: DISTRACTED DC9 CREW LATE STARTING DSCNT CAUSES INCREASED WORKLOAD AND VECTORING BY CVG APCH CTLR.
Narrative: THE FO AND I WERE BUSY BRIEFING THE APCH FOR DAYTON, AND SETTING UP OUR NAVIGATIONAL EQUIP, WHEN APCH CTL DIRECTED A DSCNT FROM 12000 FT TO 10000 FT. THE NEW ALT WAS SET IN AND POINTED TO BY BOTH PLTS, BUT AT THAT MOMENT A FLT ATTENDANT CAME INTO THE COCKPIT WITH SOME REQUEST OR PROB. SHE STAYED BRIEFLY AND LEFT, AFTER WHICH I RESUMED WHAT I WAS DOING, WHICH WAS SETTING UP RADIOS AND BRIEFING THE APCH. I DIDN'T REALIZE I HAD NOT STARTED THE DSCNT TO 10000 FT. MOMENTS LATER, THE APCH CTLR RATHER EXCITEDLY ASKED IF WE HAD YET STARTED OUT OF 12000 FT FOR 10000 FT, WHILE DIRECTING SOME OTHER ACFT TO TURN 'IMMEDIATELY.'
