TEMPORARY 'GLITCH' IN COMMUTER'S MAINT DEPT WHEN REDESIGNING THE ACFT MANIFEST FORM.

Narrative

OUR COMPANY DECIDED TO MAKE THE ACFT MANIFEST EASIER TO CALCULATE. THE NEW MANIFEST PRINTED COMBINE THE EMPTY WT AND CREW/KIT. OUR COMPANY BASES ITS CREWS AT OUT STATIONS. THE STATION WHERE I AM BASED REQUESTED A LIST OF CURRENT ACFT WTS FROM OUR MAINT DEPT. THEY COMPLIED BY SENDING US A LIST OF WTS WHICH INCLUDED THE EMPTY WTS AND THE CREW/KIT WT ALREADY COMBINED. OUR COMPANY RECEIVED SEVERAL NEW ACFT IN WHICH THE CURRENT WT LIST NEEDED TO BE UPDATED. A NEW LIST WAS SENT AND SOME OF THE WTS HAD THE CREW/KIT ADDED AND SOME DID NOT. THEN A THIRD UPDATED LIST WAS SENT WHICH ALL WTS WERE EMPTY WTS. THE LIST WORKED FINE BUT ON DEC/XX/94 WE FORGOT TO ADD THE CREW/KIT. THIS ALLOWED OUR MANIFEST CALCULATIONS TO BE 380 LBS UNDER ACTUAL WT. FORTUNATELY; AFTER RECALCULATING THE MANIFEST WE WERE STILL CONSIDERABLY UNDER OUR GROSS WT AND THE CTR OF GRAVITY WAS NOT AFFECTED. I NOTIFIED MY COMPANY OF THE MISTAKE AND MY DIRECTOR OF OPS REINFORCED THE NEED TO CHK THE WT AND BAL DATA IN THE ACFT. CORRECTIVE ACTION HAS BEEN TAKEN. ALL WT LISTS AT THE OUT STATIONS WERE DESTROYED. THE MAINT DEPT NOW UPDATES A WT LIST ON OUR COMPANY COMPUTER SYS. THE COMPUTER LIST DISPLAYS BOTH THE EMPTY WT AND THE EMPTY WT WITH THE CREW AND KIT ADDED. AND THOSE WTS ARE TO BE DOUBLE-CHKED WITH THE WT AND BAL DATA IN THE ACFT.
