Warbird & Classic Maintenance Log

Warbird maintenance is curation: factory support ended decades ago, parts are fabricated or owner-produced (with documentation requirements), radials demand oil-system and hydraulic-lock discipline, and corrosion patrol never ends. Those particulars define the record worth keeping: orphaned type support, fabricated/owner-produced parts documentation, radial engine idiosyncrasies and corrosion patrol. 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.

Preventive maintenance per Part 43 Appendix A may be owner-performed on Part 91 aircraft (with proper record entries); everything else needs appropriately certificated personnel, with inspections signed by the holders the rule specifies. The 'performed by' field in this log keeps the authority question answerable for every entry — exactly what a records review checks.

Clearing site data deletes locally stored entries — that's the price of a genuinely private, server-free design. Protect yourself with the one-click CSV download before any cleanup, OS reinstall or device change: re-importing history later beats reconstructing it from memory.

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.
