Narrative:

During scheduled maintenance it was discovered that a mathematical error transposing hobbs time to total airframe time resulted in the aircraft being flown beyond a scheduled and required maintenance inspection. Supplemental information from acn 309610: record-keeping has been revised to eliminate future errors of this sort.
