Narrative:

I was given task to grease l-hand main landing gear. I checked out the grease guns from stores without looking at the task card. I got aeroshell 33; 22; and 7; then started to lube in accordance with the drawings; using the grease specified by the drawings. I went on break and came back to finish. I was working on the card by myself. After I finished and was cleaning up; I noticed the aeroshell 33 gun on the floor with the others. I didn't think anything of it at the time; but the night and morning of jul/xa/08; I started to second-guess myself because it is possible to have used both greases. Although the drawing calls out for either aeroshell 7 or 33; I believe most mechanics use aeroshell 7 for the task. After a maintenance class I was reflecting on my maintenance practices regarding 'dirty dozen.' then I started to wonder about this since at the time I was under stress from a close friend's death and financial difficulties. I came into talk to mr X. We researched the computer to identify which aircraft was involved. A conformity order was placed on the aircraft to check task. Complacency: not reading the supplies needed on the task card. Also both aeroshell 33 and 7 greases are listed in the consumable material reference.

Title: AFTER COMPLETING A GREASE LUBE ON THE LH MAIN LANDING GEAR OF A DHC-8-400 ACFT; MECHANIC REPORTS HE MAY HAVE USED A DIFFERENT GREASE THAN THE TYPE CALLED OUT IN THE LUBE TASK CARD.

Narrative: I WAS GIVEN TASK TO GREASE L-HAND MAIN LNDG GEAR. I CHKED OUT THE GREASE GUNS FROM STORES WITHOUT LOOKING AT THE TASK CARD. I GOT AEROSHELL 33; 22; AND 7; THEN STARTED TO LUBE IN ACCORDANCE WITH THE DRAWINGS; USING THE GREASE SPECIFIED BY THE DRAWINGS. I WENT ON BREAK AND CAME BACK TO FINISH. I WAS WORKING ON THE CARD BY MYSELF. AFTER I FINISHED AND WAS CLEANING UP; I NOTICED THE AEROSHELL 33 GUN ON THE FLOOR WITH THE OTHERS. I DIDN'T THINK ANYTHING OF IT AT THE TIME; BUT THE NIGHT AND MORNING OF JUL/XA/08; I STARTED TO SECOND-GUESS MYSELF BECAUSE IT IS POSSIBLE TO HAVE USED BOTH GREASES. ALTHOUGH THE DRAWING CALLS OUT FOR EITHER AEROSHELL 7 OR 33; I BELIEVE MOST MECHS USE AEROSHELL 7 FOR THE TASK. AFTER A MAINT CLASS I WAS REFLECTING ON MY MAINT PRACTICES REGARDING 'DIRTY DOZEN.' THEN I STARTED TO WONDER ABOUT THIS SINCE AT THE TIME I WAS UNDER STRESS FROM A CLOSE FRIEND'S DEATH AND FINANCIAL DIFFICULTIES. I CAME INTO TALK TO MR X. WE RESEARCHED THE COMPUTER TO IDENT WHICH ACFT WAS INVOLVED. A CONFORMITY ORDER WAS PLACED ON THE ACFT TO CHK TASK. COMPLACENCY: NOT READING THE SUPPLIES NEEDED ON THE TASK CARD. ALSO BOTH AEROSHELL 33 AND 7 GREASES ARE LISTED IN THE CONSUMABLE MATERIAL REF.
