Narrative:

I arrived at base for my shift and the aircraft and day crew were gone; out on their X flight of the day. I clocked on in and got my flight release. They returned to base an hour plus later. The day pilot went inside to enter his flight while I refueled the aircraft and conducted a pre-flight inspection. I came inside; and began discussing the day's events with the off-going pilot. We were still talking 30 minutes later when another flight request came in. I accepted the flight; submitted my forms; quickly finished up a briefing with the crew; and walked out to the aircraft. The flight was uneventful and was completed without issue.the passenger had required full covid-19 precautionary measures; so we decontaminated the aircraft and ourselves prior to entering the base. I entered our flight info into the records; then began closing out our maintenance log book. I saw that the 10-15 hour re-torque inspection for the float step was overdue. I double-checked the numbers and the logbook to determine if it was actually overflown. Unfortunately; the latter was the case so I placed the aircraft and base out of service then notified the on-call mechanic; and the manager.going forward; the feeling of being hurried will be a cue to throttle back and be extra meticulous. Paying particular attention to things out of the ordinary will help against complacency. After a few months of slow flight volume; our base conducted [X] flights in [Y] days. That should be a cue to double-check the numbers.one possible control that would also be helpful is to patch the software to highlight inspections that are due within 10 hours in the section of the flight release request. We currently have to enter a password to override inspections that show overdue to complete the flight release request; which is a great prompt. Highlighting inspections due in less than 10 flight hours in yellow may help prevent this kind of oversight in the future.
