Narrative:

Followed instructions for this particular engineering order by removing all 6 each circuit card modules from brake steering control computer. Started to install new circuit card modules per engineering order but realized that kit was short a '3' and it had an extra '1.' this meant I couldn't complete the engineering order so I reinstalled the old circuit card modules and performed a bite check on bscu's. I didn't accomplish the engineering order and I didn't re-rack the bscu so at the time of signing the logbook I didn't feel a re-certification of catiii was necessary as called out in the engineering order upon completion. In retrospect; I'm not sure if I followed the correct procedures in the maintenance procedures manual chapter 320-23 by not re-certifying the aircraft to catiii.

Title: AN A321 ENGINEERING ORDER WAS STARTED ON THE BRAKE STEERING CTL COMPUTER BUT ACCOMPLISHMENT KIT WAS SHORT 3 COMPONENTS. RETURNED UNIT TO ENGINEERING ORDER NOT ACCOMPLISHED STATUS.

Narrative: FOLLOWED INSTRUCTIONS FOR THIS PARTICULAR ENGINEERING ORDER BY REMOVING ALL 6 EACH CIRCUIT CARD MODULES FROM BRAKE STEERING CTL COMPUTER. STARTED TO INSTALL NEW CIRCUIT CARD MODULES PER ENGINEERING ORDER BUT REALIZED THAT KIT WAS SHORT A '3' AND IT HAD AN EXTRA '1.' THIS MEANT I COULDN'T COMPLETE THE ENGINEERING ORDER SO I REINSTALLED THE OLD CIRCUIT CARD MODULES AND PERFORMED A BITE CHK ON BSCU'S. I DIDN'T ACCOMPLISH THE ENGINEERING ORDER AND I DIDN'T RE-RACK THE BSCU SO AT THE TIME OF SIGNING THE LOGBOOK I DIDN'T FEEL A RE-CERTIFICATION OF CATIII WAS NECESSARY AS CALLED OUT IN THE ENGINEERING ORDER UPON COMPLETION. IN RETROSPECT; I'M NOT SURE IF I FOLLOWED THE CORRECT PROCS IN THE MAINT PROCS MANUAL CHAPTER 320-23 BY NOT RE-CERTIFYING THE ACFT TO CATIII.
