Narrative:

On the descent phase of the flight approaching bucks intersection on V210 we were given clearance to cross bucks at 8000'. At that time we were at 300 KTS. When we got the clearance to cross bucks at 8000', based on the distance from the intersection, the captain, who was flying at that moment, decided that the altitude restriction was more important than the 250 KTS rule. We discussed the incident at the moment it happened. To our surprise, 2 days later on the same flight under the exact same conditions, the same incident happened and the captain's reaction was exactly the same, even after having discussed the previous incident. Like the previous one we descended to 7000' before reducing to 250 KTS to make the altitude restriction. I think poor planning on our part and the low experience level in the aircraft type contributed to this type of incident. In the future I will continuously remind the captain to expect bucks at 8000' and to start his speed reduction earlier.

Original NASA ASRS Text

Title: FLT CREW OF WDB ADVANCED ACFT, GIVEN CROSSING RESTRICTION OF 8000' WHEN AT 300 KIAS, MADE THE CROSSING AT 8000' BEFORE REDUCING TO 250 KTS.

Narrative: ON THE DSNT PHASE OF THE FLT APCHING BUCKS INTXN ON V210 WE WERE GIVEN CLRNC TO CROSS BUCKS AT 8000'. AT THAT TIME WE WERE AT 300 KTS. WHEN WE GOT THE CLRNC TO CROSS BUCKS AT 8000', BASED ON THE DISTANCE FROM THE INTXN, THE CAPT, WHO WAS FLYING AT THAT MOMENT, DECIDED THAT THE ALT RESTRICTION WAS MORE IMPORTANT THAN THE 250 KTS RULE. WE DISCUSSED THE INCIDENT AT THE MOMENT IT HAPPENED. TO OUR SURPRISE, 2 DAYS LATER ON THE SAME FLT UNDER THE EXACT SAME CONDITIONS, THE SAME INCIDENT HAPPENED AND THE CAPT'S REACTION WAS EXACTLY THE SAME, EVEN AFTER HAVING DISCUSSED THE PREVIOUS INCIDENT. LIKE THE PREVIOUS ONE WE DSNDED TO 7000' BEFORE REDUCING TO 250 KTS TO MAKE THE ALT RESTRICTION. I THINK POOR PLANNING ON OUR PART AND THE LOW EXPERIENCE LEVEL IN THE ACFT TYPE CONTRIBUTED TO THIS TYPE OF INCIDENT. IN THE FUTURE I WILL CONTINUOUSLY REMIND THE CAPT TO EXPECT BUCKS AT 8000' AND TO START HIS SPD REDUCTION EARLIER.
