A B727-200 WAS DISPATCHED WITH A LOGBOOK SIGNOFF FOR WORK THAT WAS NOT ACCOMPLISHED.

Narrative

I WAS ASSIGNED THE JOB OF FIXING A RAM AIR DOOR ACTUATOR ON A B727-200 IN OUR FLEET. I REMOVED THE NECESSARY ACCESS PANEL; AND PARTIALLY REMOVED THE ACTUATOR TO GAIN ACCESS TO THE CANNON PLUG ON THE INSTALLED UNIT. I DID NOT REMOVE THE UNIT COMPLETELY; NOR DID I AFFECT THE RIG ON THE CABLES ATTACHED TO THE RAM AIR DOOR THEMSELVES. I CONNECTED THE REPLACEMENT UNIT TO THE CANNON PLUG OF THE ACFT SYS AND TESTED THE NEW ACTUATOR (COMMONLY REFERRED TO FROGGING OR PIGGY-BACKING THE NEW UNIT). THE NEW UNIT DID NOT WORK; SO I FOLLOWED NECESSARY PROCS TO MAKE THE UNIT 'BAD FROM STOCK.' MY ERROR OCCURRED WHEN I INADVERTENTLY SIGNED OFF THE LOG PAGE FOLLOW-UP AS REMOVED AND REPLACED THE ACTUATOR; WHEN IN FACT I HAD NOT FULLY REMOVED THE ACTUATOR NOR HAD I REPLACED IT WITH A NEW ACTUATOR; WHICH WOULD INVOLVE RIGGING THE NEW UNIT WITH THE CABLES TO THE DOOR. MY ERROR; WHICH I UNDERSTAND IS FALSIFYING A MAINT RECORD; WAS TO NOT COMPLETELY AND ACCURATELY DESCRIBE THE WORK WHICH I HAD ACTUALLY PERFORMED.
