So here's a question I had never thought of until getting my
instrument rating and owning an IFR-equipped aircraft: how long
should records of VOR checks be retained? Do they need to be
retained at all? Can the FAA come to me and ask, "Remember that
IFR flight to SLO you made 2 years ago? Show us the VOR check for
that flight."

FAA imposes on itself a time limit for initiating investigations,
something like only 6 months. No need to be concerned about a flight
2 years ago.
