Narrative

PLANNED DEST OF SAN FRANCISCO. FE ENTERED 2 MINOR MAINT ITEMS IN ACARS. DUE TO INADEQUATE FUEL ACFT DIVERTED TO OAKLAND FOR FUEL. WHILE ON THE GND; I WENT TO CABIN TO HANDLE SOME SIGNIFICANT PAX PROBS CAUSED BY DIVERSION. ACFT WAS FUELED FOR FLT TO SFO. WHILE TAXIING FOR TKOF (NARROW TXWYS; DARK NIGHT; RAIN) ENGINEER MADE COMMENT ABOUT ACARS ENTRY FOLLOWED BY A COMMENT SIMILAR TO 'IT'S ALL RIGHT; THEY WERE ONLY INSIGNIFICANT ITEMS.' AS A RESULT THE ACFT TOOK OFF WITHOUT CLRING LOGBOOK ITEMS. I REALIZED ERROR AFTER LNDG AT SFO. ENGINEER HAD ENTERED ACARS AND LOGBOOK ITEMS WITHOUT MY KNOWLEDGE. LANGUAGE USED TO COMMUNICATE PROB ONCE DISCOVERED WAS NOT SPECIFIC AND LEFT ROOM FOR INTERP THAT EVEN THOUGH A PROB EXISTED IT HAD BEEN RESOLVED. ATTN OF CAPT AND FO WAS CONCENTRATED ON TAXI MANEUVER. AS THIS PROB WAS DISCOVERED AND UNCERTAINTY OF BEST SOLUTION DEVELOPED A CLR REQUEST FOR ASSISTANCE FOLLOWED BY A SYNERGISTIC SOLUTION (WITH ACFT PARKED; IF NECESSARY) WOULD HAVE ELIMINATED TECHNICAL ERROR. SUPPLEMENTAL INFO FROM ACN 328278: OPEN LOGBOOK ITEMS WERE COCKPIT FLOOR AND COCKPIT DIRTY AND 2 LAVS WITHOUT WATER TO FLUSH. AFTER BLOCKING OUT OF OAKLAND I REALIZED I FORGOT TO CALL UP MAINT TO CLR ITEMS WRITTEN UP. I MENTIONED LOG ITEMS TO CREW. I CAN'T BE SURE IF THE CAPT HEARD ME; AND I DID NOT BELIEVE ITEMS WERE SAFETY RELATED TO OUR FLT; SO I SAID 'NEVER MIND.' I ATTRIBUTE ABOVE TO FATIGUE AFTER A 13 OR 14 HR DUTY DAY. IT WAS BROUGHT TO MY ATTN BY THE CAPT THE FOLLOWING DAY. SUPPLEMENTAL INFO FROM ACN 328279: WX DELAYS AT SFO CAUSED 30 MINS OF HOLDING (AIRBORNE) FOLLOWED BY DIVERSION TO OAK. DURING GND REFUELING AND FLT PLANNING; FLT ATTENDANT CAME FORWARD WITH PROBS OF ONE 'GENTLEMAN' GRABBING ANOTHER'S CROTCH; AN EXECUTIVE GOING BALLISTIC AND 300 PAX WANTING CONNECTION INFO AT SFO. WE WERE GIVEN A DEP TIME SLOT FOR THE RETURN LEG TO SFO. THE CAPT AND I WERE USING THE ARPT DIAGRAM AND FOLLOWING PROGRESSIVE TAXI INSTRUCTIONS TO THE RWY BECAUSE OF RAIN/LOW VISIBILITY; AND UNFAMILIARITY WITH THE FIELD. THAT ONE LAST DISTR DIDN'T REGISTER AND WE SUBSEQUENTLY TOOK OFF IN VIOLATION OF FARS. GIVEN A SIMILAR SEQUENCE OF EVENTS I CAN'T HONESTLY SAY IT WON'T HAPPEN AGAIN.
