Narrative:

During signoff of defect; I used a Q400 wire diagram reference instead of the correct crj reference. Incorrect reference: Q400 w--D 34-44-01. Correct reference: crj w--D 34-44-04. All other references used in the signoff are correct. I used the correct reference when working at the aircraft. When I returned to the line shack area; I left the manual on the table. During the time I was putting away my tools; the manual was returned back with the rest of the manuals. I also performed wing walker duties on an aircraft moving out of the hangar. When I returned; I grabbed the Q400 wire diagram by mistake and used its reference in my signoff. I was scanning aircraft history for X and I noticed my signoff had the Q400 reference. Told supervisor and filled out a safety report. Things were a little hectic at this time due to aircraft movement in and out of the hangar getting ready for morning flts. I was distraction because I was called upon to walk wing on an aircraft moving out of the hangar. Suggestions: 1) not become distraction during the times I am performing my signoffs. 2) should have done the signoff before putting my tools away.

Title: MECH RPTS ON USING A Q400 WIRE DIAGRAM REF INSTEAD OF THE CORRECT CRJ-700 REF CHAPTER DURING SIGNOFF OF DEFECT. CORRECT REF WAS USED WHEN WORKING AT THE ACFT.

Narrative: DURING SIGNOFF OF DEFECT; I USED A Q400 WIRE DIAGRAM REF INSTEAD OF THE CORRECT CRJ REF. INCORRECT REF: Q400 W--D 34-44-01. CORRECT REF: CRJ W--D 34-44-04. ALL OTHER REFS USED IN THE SIGNOFF ARE CORRECT. I USED THE CORRECT REF WHEN WORKING AT THE ACFT. WHEN I RETURNED TO THE LINE SHACK AREA; I LEFT THE MANUAL ON THE TABLE. DURING THE TIME I WAS PUTTING AWAY MY TOOLS; THE MANUAL WAS RETURNED BACK WITH THE REST OF THE MANUALS. I ALSO PERFORMED WING WALKER DUTIES ON AN ACFT MOVING OUT OF THE HANGAR. WHEN I RETURNED; I GRABBED THE Q400 WIRE DIAGRAM BY MISTAKE AND USED ITS REF IN MY SIGNOFF. I WAS SCANNING ACFT HISTORY FOR X AND I NOTICED MY SIGNOFF HAD THE Q400 REF. TOLD SUPVR AND FILLED OUT A SAFETY RPT. THINGS WERE A LITTLE HECTIC AT THIS TIME DUE TO ACFT MOVEMENT IN AND OUT OF THE HANGAR GETTING READY FOR MORNING FLTS. I WAS DISTR BECAUSE I WAS CALLED UPON TO WALK WING ON AN ACFT MOVING OUT OF THE HANGAR.
