Narrative:
A dent in tail cone exists on aircraft xyz. It was inspected in ZZZ on jul/xa/99, damage log #xyxxx, and found within limits per srm. On sep/xa/99 a deferral was issued #xyww which was updated after evaluating the time of estimated completion of the repair. It was clear the aircraft would not make schedule. The dent is not going to affect the aircraft's airworthiness, so we deferred it until a time when we could have the aircraft on ground for repair 3 days.
