Narrative:

An MEL item was added to the flight release. The logbook was signed off by maintenance and a placard installed. Our company procedure for inoperative component was followed at the gate. Our MEL crew procedure section refers us to the supplemental section of our cockpit operating manual. This section has us verify some of the maintenance actions, but not all of them. The dispatch deviation guide contains the remainder of the items that is to be performed by mechanics. Once airborne, it was discovered that all the maintenance procedures were not followed. Maintenance department was notified and instructed crew to complete the procedures. From a human factors standpoint, the checks and balances did not occur perhaps due to too many references need to be checked to ensure MEL compliance. All references do not refer to each other once a different manual is referred to as the crews prepare for departure. One factor which contributes to human performance is short turnaround times for flcs and maintenance personnel.

OUR MEL CREW PROC SECTION REFERS US TO THE SUPPLEMENTAL SECTION OF OUR COCKPIT OPERATING MANUAL. THIS SECTION HAS US VERIFY SOME OF THE MAINT ACTIONS, BUT NOT ALL OF THEM.

MAINT DEPT WAS NOTIFIED AND INSTRUCTED CREW TO COMPLETE THE PROCS. FROM A HUMAN FACTORS STANDPOINT, THE CHKS AND BALS DID NOT OCCUR PERHAPS DUE TO TOO MANY REFS NEED TO BE CHKED TO ENSURE MEL COMPLIANCE. ALL REFS DO NOT REFER TO EACH OTHER ONCE A DIFFERENT MANUAL IS REFERRED TO AS THE CREWS PREPARE FOR DEP. ONE FACTOR WHICH CONTRIBUTES TO HUMAN PERFORMANCE IS SHORT TURNAROUND TIMES FOR FLCS AND MAINT PERSONNEL.
