Narrative:
Was told by dayton approach to descend from 6000 ft MSL to 4000 ft MSL. I am often given discretion to 4000 ft on this particular route. Dayton came on 13 mi later and asked me why I had not descended to 4000 ft. I immediately initiated a descent to 4000 ft. No evasive was taken or needed. There were no conflicts with other aircraft. I was in fault for not descending right away. I will be more careful in the future and have learned from this mistake.
