Altitude deviation altitude overshot in descent. As a result, there was a speed deviation as well, being under 10000 ft.

Narrative:
During descent PF failed to insure speed was reduced to 250 KTS at 10000 ft. Autoplt was engaged and during leveloff with autoplt, aircraft descended to approximately 9500 ft MSL at approximately 300 KTS. Contributing factors: 1) not initiating leveloff earlier. 2) ongoing communications with day approach control. 3) first officer briefing the approach later than he should have. Speed excursion discovered when day approach advised to slow to 210 KTS. Corrective action: crew deployed speed brakes and quickly slowed to 250 KTS then 210 KTS. Future prevention: insure that first officer completes approach briefing at cruise altitude prior to accepting descent. First officer could have PNF give briefing while the first officer kept flying the aircraft.
Original NASA ASRS Text
Title: ALTDEV ALT OVERSHOT IN DSCNT. AS A RESULT, THERE WAS A SPD DEV AS WELL, BEING UNDER 10000 FT.
Narrative: DURING DSCNT PF FAILED TO INSURE SPD WAS REDUCED TO 250 KTS AT 10000 FT. AUTOPLT WAS ENGAGED AND DURING LEVELOFF WITH AUTOPLT, ACFT DSNDED TO APPROX 9500 FT MSL AT APPROX 300 KTS. CONTRIBUTING FACTORS: 1) NOT INITIATING LEVELOFF EARLIER. 2) ONGOING COMS WITH DAY APCH CTL. 3) FO BRIEFING THE APCH LATER THAN HE SHOULD HAVE. SPD EXCURSION DISCOVERED WHEN DAY APCH ADVISED TO SLOW TO 210 KTS. CORRECTIVE ACTION: CREW DEPLOYED SPD BRAKES AND QUICKLY SLOWED TO 250 KTS THEN 210 KTS. FUTURE PREVENTION: INSURE THAT FO COMPLETES APCH BRIEFING AT CRUISE ALT PRIOR TO ACCEPTING DSCNT. FO COULD HAVE PNF GIVE BRIEFING WHILE THE FO KEPT FLYING THE ACFT.
