ACR WDB SPD DEV. EXCEEDED 250 AT 5000 FT ON A PROFICIENCY CHK FLT.

Narrative

I WAS FLYING AS EXAMINEE (CAPT) ON A SECTION 609 FLT CHK. THE AIRMAN IN THE R SEAT (ACTING COPLT) WAS A QUALIFIED CHK AIRMAN AND DFE. THE FAA EXAMINER WAS SEATED IN THE #1 JUMP SEAT. DURING THE THIRD OF A SERIES OF DEPS; AS PART OF THE CLEAN-UP; AFTER FLAP RETRACTION; I ORDERED 'FL CHANGE; SPD VREF +80.' FL CHANGE WAS CALLED TO INSURE ALT CAPTURE AS HIGH RATES OF CLB WERE PRODUCED BECAUSE OF COLD OUTSIDE AIR TEMP AND LIGHT WT. 'VREF +80' (211 KTS) WAS CALLED TO ENGAGE AUTOTHROTTLES IN SPD MODE; BUT THEY DID NOT ENGAGE. THE COPLT MADE NO CALL UNTIL CALLING 'SOD'; I NOTED THE IAS GOING THROUGH 253 KTS AND THE THROTTLES WERE STILL AT THE TKOF SETTING. I PULLED THE THROTTLES TO IDLE; BUT (ACCORDING TO THE FAA EXAMINER'S NOTES) THE SPD WENT TO 276 KTS BEFORE DECELERATING. I RESET THE SPD WINDOW TO 240 AND REENGAGED THE AUTOTHROTTLES SATISFACTORILY. I BELIEVE MY COPLT (BOTH AS COPLT AND AS PIC) SHOULD HAVE BROUGHT MY ATTN TO THE EXCEEDANCE AS SOON AS 211 KTS WAS PASSED; OR AT LEAST SOON ENOUGH TO PREVENT THE AIRPLANE FROM EXCEEDING 250. THE DUTIES OF A PLT SHOULD ALWAYS INCLUDE NOTING AND CALLING POSSIBLE EXCEEDANCES AND VARIATIONS; PARTICULARLY WHEN INVOLVED IN OTHER THAN COMMON (ROUTINE) OPS.
