A B747-200 CREW OVER-SPED THE FLAPS ON TKOF BECAUSE OF ATC CLRNCS OFF RTE THAT DIVERTED THEIR ATTN FROM COMPLETING THE AFTER TKOF CHKLIST.

Narrative

OUR CREW WAS ON DUTY 7+ HRS PRIOR TO OUR DEP FROM ZZZ DUE TO MAINT ISSUES. DURING OUR DEP FROM ZZZ WE RECEIVED MULTIPLE CLRNC AND FREQ CHANGES FROM ATC IN A VERY SHORT TIME-FRAME. ATC GAVE US CLRNC TO PROCEED DIRECT TO POINTS WHICH WERE NOT A PART OF THE DEP PROFILE OR ON OUR FLT PLAN. THIS HAD DIVERTED SOME OF OUR ATTN FROM OUR PRIMARY TASK OF FLYING THE ACFT BECAUSE WE WERE LOOKING UP THIS INFO THAT ATC REQUESTED US TO DO. THIS MAY HAVE ADDED SOME CONFUSION IN THE COCKPIT WHILE WE WERE REVIEWING OUR MAPS AND FLT PLAN. AFTER THINGS SETTLED DOWN; WE DISCOVERED THAT OUR FLAPS WERE STILL DOWN. WE PROCEEDED TO RETRACT THE FLAPS. ALL INDICATIONS APPEARED TO BE NORMAL WITH NO ADVERSE FLT CHARACTERISTICS AT THAT TIME. WE THEN CONTACTED OUR COMPANY AND STATED OUR PROB THAT WE HAD OVER-SPED THE FLAPS ON OUR ACFT. IT WAS OVER 2 HRS LATER THAT THE COMPANY REQUESTED THAT WE RETURN TO ZZZ. UPON OUR ARR INTO ZZZ WE DID NOT ENCOUNTER ANY PROBS WITH OUR FLAPS. ALL INDICATOR NORMAL AND LNDG WAS UNEVENTFUL. ON THE FLT THE CAPT WAS THE PF. WHILE WE WERE FLYING THE DEP PROFILE ON RAW DATA; I WAS TUNING RADIOS; SETTING HIS CROSS RADIALS AND ACCEPTING NEW ALT CLRNCS AND CHKING OUR POS FOR OUR NEXT TURNING POINT AND RECEIVING NEW FREQ CHANGES FROM ATC. THE LAST COMMAND I HEARD FROM THE CAPT WAS FLAPS 1 DEG AND SPD MODE IAS. I DID NOT HEAR HIM CALL FOR FLAPS UP NOR DID I HEAR HIM CALL GREEN LIGHT TO BRING THE FLAPS UP. I'M NOT SAYING HE DID NOT COMMAND THAT BUT I DID NOT HEAR HIM SAY THOSE WORDS. IF I WAS BUSY HE SHOULD HAVE REPEATED HIS COMMAND TO ME AGAIN TO GET MY ATTN OR SIGNAL ME. AS PER OUR COMPANY PROC THE PLT MONITORING SHOULD CALL THE GREEN LIGHT WHEN HE SEES IT. ALSO I DID NOT SEE THE GREEN LIGHT NOR DID I HEAR ANYONE CALL GREEN LIGHT WHICH WOULD HAVE SIGNALED ME TO BRING THE FLAPS UP. ATC HAD ME PRETTY BUSY TRYING TO FIGURE OUT WHERE THEY WANTED US TO GO. ALSO OUR LONG DUTY DAY PRIOR TO DEP WAS A FACTOR IN THE PROB. SUPPLEMENTAL INFO FROM ACN 712817: CONTRIBUTING FACTORS: LONG PREFLT DELAY DUE TO MAINT. CAPT AND FO BOTH LOW TIME IN B747.
