A CRJ700 RECEIVED INTERMITTENT 'STALL FAIL' MSG'S AFTER TKOF. MAINT FAILED TO REMOVE TAPE FROM AN AOA VANE AFTER TESTING IT AND THE FO MISSED IT ON PREFLT.

Narrative

AFTER ARRIVING TO ZZZ FOR DEP FLT FO BEGAN THE PREFLT AND I BEGAN MY COCKPIT SCAN AND FIRST FLT OF THE DAY CHKS. ACFT WAS HOT AND HAD JUST BEEN PULLED UP TO THE GATE BY MAINT. A GATE AGENT ON THE ACFT COMPLAINED ABOUT THE ACFT BEING BROUGHT UP SO LATE. SHORTLY AFTERWARD; MAINT BROUGHT THE AML AND I SIGNED OFF THE LOGBOOK. THEN MAINT CAME BACK AND TOOK THE AML FROM ME. MEANWHILE; I BEGAN LOOKING AT THE RELEASE AND FLT PLAN. I NOTICED AT THAT POINT THAT THERE WAS A DISCREPANCY BTWN THE AML AND THE RELEASE. SPECIFICALLY; THE RELEASE SHOWED A MEL THAT WAS NOT IN THE AML; THE IGNITER SYS. WHEN THE AML WAS RETURNED; NOW SIGNED OFF FOR RVSM; I ASKED ABOUT MEL ON THE RELEASE AND THE MAINT TECHNICIAN SAID THAT MEL HAD BEEN CLRED. SO I BEGAN THAT COORD WITH DISPATCH. A DELAY WAS TAKEN OF APPROX 12 MINS WHILE WAITING FOR DISPATCH. I'M CONVEYING THESE DETAILS TO EXPOSE THE ATMOSPHERE ON THAT MORNING BECAUSE IT DISPLAYS THE FRENZIED NATURE THAT MAINT HAD TAKEN. SHORTLY AFTER TKOF I RECEIVED AN EICAS MESSAGE STALL FAIL WHICH WOULD COME AND GO ERRATICALLY. AT TIMES IT REMAINED OFF. THE ACFT WAS WRITTEN UP FOR THE DISCREPANCY UPON ARR AT ZZZ. I LEARNED LATER THAT TAPE HAD BEEN FOUND ON ONE OF THE AOA VANES; FROM MAINT DOING SOME OF THEIR CHKS. IT'S MY BELIEF THAT THE AML SHOULD BE CHKED ON BOARD BEFORE ANY CHKS ARE DONE; INCLUDING THE COCKPIT SAFETY SCAN OR INCLUDED THERE WITHIN. FURTHER; FLT ATTENDANTS AND PAX SHOULD NOT BE ALLOWED TO BOARD UNTIL THE ACFT IS PROPERLY RELEASED TO THE LINE. MAINT DISCOVERED THE TAPE ON THE AOA AFTER IT WAS WRITTEN IN THE AML. EVENT OCCURRED BECAUSE FO DID NOT OBSERVE THE TAPE ON THE AOA VANE. MAINT SHOULD NOT RELEASE AN ACFT UNTIL ALL REQUIRED LOG ENTRIES ARE COMPLETE. I BELIEVE THAT THE MAINT TECHNICIAN SHOULD NOT BE TRYING TO COMPLETE HIS DUTIES WHILE THE ACFT IS BEING BOARDED AND PLTS ARE TRYING TO COMPLETE COCKPIT CHKS. EITHER THE ACFT IS READY TO BE RELEASED TO THE LINE OR IT'S NOT. ADDITIONALLY; FO IS AT FAULT FOR NOT DISCOVERING THE TAPE ON THE AOA VANE. SUPPLEMENTAL INFO FROM ACN 794153: I WAS INFORMED THAT THERE WAS AN INFLT CAUTION MESSAGE STALL FAIL THAT OCCURRED ON ACFT. UPON INSPECTION THERE WAS SPD TAPE FOUND ON R AOA VANE. TAPE WAS REMOVED AND ACFT WAS RETURNED TO SVC. THIS WAS A FAIRLY ROUTINE TASK; HOWEVER THERE WERE SEVERAL PEOPLE WORKING THIS TASK. I PERSONALLY DID NOT INSTALL THE SPD TAPE BUT OBVIOUSLY IT WAS AND NOT DETECTED BEFORE DEP BY MAINT OR THE FLT CREW.
