Narrative:
Aircraft was descending for approach into ont airport at 250 KTS. Aircraft was then cleared for a visual approach. Aircraft was high and fast for normal approach. PF disconnected the autoplt and applied full speed brakes to expedite descent and to position the aircraft for a normal approach. PNF was 'looking outside' for traffic. Aircraft inadvertently exceeded 250 KTS, up to maybe 265 KTS, during the descent. PF immediately corrected the situation by slowing the aircraft upon notice of airspeed. Final approach and landing were normal and uneventful. During descent for visual approachs into ont, aircraft are usually held up high. Aircraft should be slowed and configured earlier than normal to prevent a 'slam dunk' situation and to avoid the recurrence of the above situation.
Original NASA ASRS Text
Title: AN A320 FLT CREW IS HELD UP HIGH ON APCH WHICH LEADS TO ACFT SPD DEV WHILE TRYING TO DSND.
Narrative: ACFT WAS DSNDING FOR APCH INTO ONT ARPT AT 250 KTS. ACFT WAS THEN CLRED FOR A VISUAL APCH. ACFT WAS HIGH AND FAST FOR NORMAL APCH. PF DISCONNECTED THE AUTOPLT AND APPLIED FULL SPD BRAKES TO EXPEDITE DSCNT AND TO POS THE ACFT FOR A NORMAL APCH. PNF WAS 'LOOKING OUTSIDE' FOR TFC. ACFT INADVERTENTLY EXCEEDED 250 KTS, UP TO MAYBE 265 KTS, DURING THE DSCNT. PF IMMEDIATELY CORRECTED THE SIT BY SLOWING THE ACFT UPON NOTICE OF AIRSPD. FINAL APCH AND LNDG WERE NORMAL AND UNEVENTFUL. DURING DSCNT FOR VISUAL APCHS INTO ONT, ACFT ARE USUALLY HELD UP HIGH. ACFT SHOULD BE SLOWED AND CONFIGURED EARLIER THAN NORMAL TO PREVENT A 'SLAM DUNK' SIT AND TO AVOID THE RECURRENCE OF THE ABOVE SIT.
