Narrative:

Due to pilot oversight; my VFR transponder certification went overdue. The aircraft was not operated within class B airspace and never entered within the 30 NM veil surrounding any class B airport. Additionally; non-towered airports were transited during this period. The oversight occurred during the corona virus covid-19 lock down. I have instituted a tracking system which will help me to better track future mandatory inspections.
