MECH FAILED TO UNLOCK HI STAGE BLEED VALVE AND REVIEW THE MEL IN THE LOGBOOK TO RETURN THE AIRPLANE TO SVC APPROPRIATELY.

Narrative

ON ACFT X I REPLACED THE OVERTEMP AND BLEED AIR SENSORS TO THE R ENG AS CALLED OUT BY SOP. AFTER LEAK CHK USING APU AIR PRESSURE; I REMOVED L HAND BLEED SWITCH 'INOP' STICKER. I DID NOT REVIEW MEL TO RETURN SYS TO NORMAL; THEREFORE THE L HAND HI-STAGE VALVE WAS STILL LOCKED CLOSED. SEVERAL HRS AFTER X HAD DEPARTED; I REALIZED I HAD NOT CHKED THE MEL. AFTER REVIEW OF THE MEL; I CALLED SFO AND THEY ISSUED A NOTICE TO CORRECT THE PROB. TO PREVENT FUTURE OVERSIGHT; I WILL LOOK AT PROB AND MEL PROCS BEFORE STARTING A JOB. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: THE RPTR COULD NOT RECALL IF THE PROB AIRPLANE WAS A 757 OR 767. HE DID RECALL THE MEL DID NOT SEEM TO BE WRITTEN FOR THE MECH IN A HURRY. THE MECH TENDS TO GET CARRIED AWAY; HE SAYS; WITH TROUBLESHOOTING THE PROB; AND; FORGETTING TO STAND BACK AND REFER TO THE MEL AND PRINTED MATERIAL RELATED TO THE PROB. HE SAID THERE IS NO INSPECTOR REQUIRED TO CHK MECH'S WORK EXCEPT ON SUCH SAFETY OF FLT ITEMS AS FLT CTLS. THERE WERE NO REPERCUSSIONS FROM THE FAA.
