Narrative:
Aircraft was in gate 10 mins prior to departure time. Circular area noted on aft tail cone by baggage personnel. Inspected damaged area on non structural fiberglass center area of tailcone. Cracked out area depressed in center approximately 1/8 inch. I determined repair work not required at this time. Speed taped over crack. In my experience, I thought this was a satisfactory interim repair. I failed to use reference material, structural repair manual, as I felt this was not an airworthy item caused by time considerations -- aircraft use.
