Narrative

ON TAXI OUT OF SJU; WHEN CAPT WENT TO ARM THE AUTOBRAKES FOR TKOF THE SELECTOR WOULD NOT REMAIN IN THE REJECTED TKOF POS AND THE AUTOBRAKE LIGHT ILLUMINATED. WE PULLED INTO THE HOLDING AREA TO CHK THE ACFT MEL. AFTER CAPT REFERRED TO THE MEL; HE DETERMINED THAT WE COULD NOT CREW PLACARD THE AUTOBRAKES. CAPT THEN CALLED DISPATCH AND TULSA TECHNICIAN TO INFORM THEM OF OUR SIT. MAINT TECHNICIAN THEN TOLD CAPT THAT WE COULD CREW PLACARD THE AUTOBRAKES AND DIRECTED HIM TO ANOTHER CHAPTER OF THE MEL. THIS SECTION OF THE MEL STATED THAT THE CREW COULD PLACARD THE AUTOBRAKES. MAINT TECHNICIAN; CAPT AND DISPATCH ALL CONCURRED THAT WE COULD DISPATCH THE ACFT IN ITS CURRENT CONDITION. WE DEPARTED SJU. WHEN WE REACHED CRUISE ALT CAPT WAS FILLING OUT THE NECESSARY PAPERWORK TO COMPLETE THE CREW PLACARDING. HE THEN BECAME UNSURE AS TO WHETHER CREW PLACARDING WAS ALLOWED IN THIS SIT. EVEN THOUGH HE HAD DESCRIBED THE ACFT CONDITION TO MAINT TECHNICIAN IN DETAIL; INCLUDING THE FACT THAT THE AUTOBRAKE LIGHT WAS ILLUMINATED; IT APPEARED THAT MAINT TECHNICIAN HAD GIVEN HIM INCORRECT INFO. WHEN WE LANDED IN BDL CAPT CALLED MAINT TECHNICIAN AGAIN TO CLARIFY THE SIT; AND WAS TOLD BY A DIFFERENT TECHNICIAN THAT IN THAT PARTICULAR SIT THE MEL DID NOT ALLOW CREW PLACARDING. WHEN CAPT ASKED WHY SOMEONE IN MAINT TECHNICIAN WOULD GIVE HIM INACCURATE INFO REGARDING THE MEL; THE TECHNICIAN STATED; THAT GUY IS AN IDIOT. APPARENTLY NOT EVERYONE IN MAINT IS WELL VERSED ON THE MEL. SOMETHING THAT CAME AS A SURPRISE TO EVERYONE INVOLVED WAS A LITTLE SURPRISED BY THE FACT THAT SOMEONE IN MAINT WOULD MISLEAD THE CREW AND DISPATCH REGARDING AN MEL ITEM. I HAD ALWAYS IN MY MIND THOUGHT OF MAINT TECHNICIAN AS THE EXPERTS IN THE MEL/MAINT DEPT. HOWEVER; THIS SIT HAS PROVEN ME WRONG.
