Light-Sport Maintenance Log

LSA maintenance runs on the manufacturer's maintenance manual: it defines what an owner, an LSRM and an A&P may each do — a delegation structure unique to the category, where the manual (not Part 43 alone) is the authority. Those particulars define the record worth keeping: maintenance authority flows from the manufacturer's maintenance manual and your LSRM/A&P arrangements, with annual condition inspections. A log structured around them (rather than a generic 'date/work' diary) means the patterns and recurring obligations of THIS kind of operation stay visible — which is most of what separates well-maintained examples from the other kind.

The manufacturer's maintenance manual is the authority: it specifies which tasks are owner-performable, which need an LSRM (light-sport repairman with maintenance rating) and which need an A&P. The annual condition inspection needs an LSRM-M or A&P. Keep the manual's task authorisations in mind per entry — the 'performed by' field here exists so that question is always answerable.

By design: operational records are sensitive, and the simplest privacy guarantee is never transmitting them. Local-only storage means zero servers, zero breach surface and zero subscription. If you work from several devices, keep one as the master record and move snapshots with the CSV export.

A plain CSV with one row per entry and labelled column headers — the most portable format there is. Spreadsheets open it directly, most specialised software can map it on import, and a printed copy is perfectly legible to a human reviewer. Nothing proprietary means your maintenance history is never trapped here.
