Narrative:

I, maintenance control supervisor for air carrier, issued a deferral placard on the aft airstair control handle, exterior position, as inoperative. The placard was an 'information' placard. The inside handle worked ok. It was brought to my attention the next day, nov/tue/93, that the placard was illegal due to the fact that the exterior handle is also considered to be an emergency item, as well as the inside control handle. Contributing factors for this error include the following: 1) extremely busy working other aircraft when the placard was requested. 2) aircraft was fully loaded and ready for departure at time of call. 3) ignorance or forgetfulness of the far on my part, that the outside control handle was considered an emergency item, since the inside handle worked ok. Need to decrease workload in maintenance control.
