An Aircraft Inspector reports a Mechanic informed him the forward right Service/Emergency door inner access panels had not been removed as required during A-Checks to accomplish the door Lube Task Card on two CRJ-200 aircraft. The original factory Quality Assurance label was still installed on the inner panel to door frame; in perfect condition; since the aircraft was built.

Narrative

A CRJ-200 aircraft 'X' was in for RON (Routine Overnight Maintenance) maintenance with an A-Check; a Mechanic brought a problem to my attention. The previous week he worked on an A-check on a forward service door and again tonight was working the forward service door lube part of an A-check. Both times the inner access panels required to be removed for the lube task 52-00-00 were not removed as per the Task Card. The paper [type] factory Quality Assurance (QA) label was still installed on the panel to door frame; still in perfect condition. I forwarded a picture of door and seals to a manager and a copy of Job Card and Task Card and AMM access panel reference; which shows which panels were not removed and what lube points where missed since aircraft was built.This lube task should be done every other A-Check. The two aircraft I seen in this two week period had not had access panels removed. I'm sorry I do not remember the first aircraft; but aircraft 'X' had panels removed and old dried out grease removed and then lubricated correct as per Task Card.A fleet inspection and lube IAW (In Accordance With) Task Card should be done on forward service door to see which aircraft have actually had correct lube done. This Task 52-00-00 should be removed from the A-Check and controlled separately; since this task takes approximately three hours to do; so it can be scheduled with a slower night with a Service Check or something on that line.The Task Card only shows that this job takes .03 Man hours which is about six seconds; which may had lead to confusion on [Maintenance] Planning's part. I spoke to a few mechanics on the floor and this lube usually gets pushed to the end of the night; when nobody wants to do it and half of them did not even know they were supposed to remove the panels. The Task Card is clear on what needs to be done; just the timing needs to be adjusted.
