Narrative:

The way the job cards sign off for this task on ETOPS type aircraft for my carrier, was blended in with a task atop of it on the signoff sheet. I placed off, all the task to be performed, a water chlorination task was not assigned due to the misplaced way it was on the signoff sheet. I overlooked this task at approximately XA30 while preparing to move this aircraft. It was brought to my attention: task was not assigned. I took the sheet, signed it. Told the mechanic not to worry 'I'll take care of it' and guess they will drink bottle water (I will defer it later). As I finished this I was told that a company we provide overnight maintenance needed their plane now for an XC10 departure. Since I was the only taxi person for type aircraft, I took the plane to the needed gate and arrived back at my hangar at XD00. Have now forgotten to defer the water chlorination, and still with another aircraft that I had to get out. While I was away, an upgrade lead placed my work pack in the complete check. A supervisor questioned me on the water, and I told him it was not done and I'm going to get a defer on it. He wanted it done. Tried to get men to do task, since it was end of tour. No takers. Went and deferred task. Contributing factor: getting too involved in too many tasks.

Narrative: THE WAY THE JOB CARDS SIGN OFF FOR THIS TASK ON ETOPS TYPE ACFT FOR MY CARRIER, WAS BLENDED IN WITH A TASK ATOP OF IT ON THE SIGNOFF SHEET. I PLACED OFF, ALL THE TASK TO BE PERFORMED, A WATER CHLORINATION TASK WAS NOT ASSIGNED DUE TO THE MISPLACED WAY IT WAS ON THE SIGNOFF SHEET. I OVERLOOKED THIS TASK AT APPROX XA30 WHILE PREPARING TO MOVE THIS ACFT. IT WAS BROUGHT TO MY ATTN: TASK WAS NOT ASSIGNED. I TOOK THE SHEET, SIGNED IT. TOLD THE MECH NOT TO WORRY 'I'LL TAKE CARE OF IT' AND GUESS THEY WILL DRINK BOTTLE WATER (I WILL DEFER IT LATER). AS I FINISHED THIS I WAS TOLD THAT A COMPANY WE PROVIDE OVERNIGHT MAINT NEEDED THEIR PLANE NOW FOR AN XC10 DEP. SINCE I WAS THE ONLY TAXI PERSON FOR TYPE ACFT, I TOOK THE PLANE TO THE NEEDED GATE AND ARRIVED BACK AT MY HANGAR AT XD00. HAVE NOW FORGOTTEN TO DEFER THE WATER CHLORINATION, AND STILL WITH ANOTHER ACFT THAT I HAD TO GET OUT. WHILE I WAS AWAY, AN UPGRADE LEAD PLACED MY WORK PACK IN THE COMPLETE CHK. A SUPVR QUESTIONED ME ON THE WATER, AND I TOLD HIM IT WAS NOT DONE AND I'M GOING TO GET A DEFER ON IT. HE WANTED IT DONE. TRIED TO GET MEN TO DO TASK, SINCE IT WAS END OF TOUR. NO TAKERS.
