Narrative:
As soon as we got the handoff, approach turned us 30 degrees right and cleared us to 5000 ft with a request to expedite descent. The captain then initiated the descent out of 12000 ft at a good rate. As we approached 10000 ft, the first officer was communicating with unicom reference customs agent, so airspeed call at 10000 ft was late, aircraft was going through 9500 ft before airspeed was reduced to 250 KIAS. Combination of events, and their timing, in association with the crew's expectance of a standard clearance contributed to the airspeed excursion. Even though there was no conflict with other traffic, the heavy communication workload delayed the checklist long enough to allow the airspeed deviation.

Title: FLC OF AN MDT BUSINESS JET EXCEEDED THE MAX AIRSPD BELOW 10000 FT DURING DSCNT FOR LNDG.
Narrative: AS SOON AS WE GOT THE HDOF, APCH TURNED US 30 DEGS R AND CLRED US TO 5000 FT WITH A REQUEST TO EXPEDITE DSCNT. THE CAPT THEN INITIATED THE DSCNT OUT OF 12000 FT AT A GOOD RATE. AS WE APCHED 10000 FT, THE FO WAS COMMUNICATING WITH UNICOM REF CUSTOMS AGENT, SO AIRSPD CALL AT 10000 FT WAS LATE, ACFT WAS GOING THROUGH 9500 FT BEFORE AIRSPD WAS REDUCED TO 250 KIAS. COMBINATION OF EVENTS, AND THEIR TIMING, IN ASSOCIATION WITH THE CREW'S EXPECTANCE OF A STANDARD CLRNC CONTRIBUTED TO THE AIRSPD EXCURSION. EVEN THOUGH THERE WAS NO CONFLICT WITH OTHER TFC, THE HVY COM WORKLOAD DELAYED THE CHKLIST LONG ENOUGH TO ALLOW THE AIRSPD DEV.
