ACR CAPT IS ADVISED 2 DAYS LATER BY FO THAT LOGBOOKS WERE NOT COMPLETED.

Narrative

AFTER THE FIRST 2 LEGS OF A 3-DAY TRIP; WE ARRIVED AT MDW AND WERE TOLD THAT WE HAD A CALL FROM SCHEDULING. I WAS TOLD THAT I WOULD BE REROUTED OFF MY ORIGINAL PAIRING AND THE FO WAS TO STAY ON THE ORIGINAL SEQUENCE; BUT THAT HE WOULD HAVE AN UNSCHEDULED ACFT CHANGE. WE EACH MADE PREPARATION TO FOLLOW OUR NEW INSTRUCTIONS. AS I WAS TO REMAIN ON THE SAME ACFT; I BEGAN LOOKING FOR MY NEW FO. DUE TO A GATE CHANGE; HE WAS AT THE WRONG GATE AND IT TOOK SEVERAL MINS TO LOCATE HIM. THE FOLLOWING DAY; I REJOINED MY ORIGINAL SEQUENCE AND WAS TOLD BY THE ORIGINAL FO THAT WE HAD NOT ENTERED OUR FIRST 2 LEGS IN THE LOGBOOK. WE CONTACTED DISPATCH; THEN SCHEDULING; AND THEY MADE ARRANGEMENTS TO HAVE THE INFO ENTERED. THE FO STATED THAT DUE TO ENRTE WX; HE DID NOT FILL OUT THE LOGBOOK ENRTE; AND HAD PLANNED TO DO SO AT MDW. ONCE ARRIVING AT MDW; THE ACFT CHANGE BECAME FOREMOST IN HIS MIND; AND HE FAILED TO DO IT AT THAT TIME. I DID NOT NOTICE ENRTE THAT WE HADN'T FILLED IT OUT AND WAS SIMILARLY DISTR ON THE GND DURING THE CHANGE. IN THE FUTURE; I WILL ENSURE THAT THE BOOK IS COMPLETED EVEN DURING HECTIC TIMES.
