Seaplane & Float Maintenance Log

Water operations accelerate everything corrosive: saltwater exposure starts a clock that freshwater rinses partially reset, float compartments hide leaks until weighed, and attach fittings carry inspection cycles that wheels-only aircraft never see. Those particulars define the record worth keeping: corrosion inspection cadence, float compartment pump-outs and attach-fitting checks, freshwater vs saltwater exposure tracking. 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.

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.

Always — the CSV export is a complete, lossless dump of your maintenance history, generated locally in one click. Import it into commercial software, archive it with your files, or post-process it in a spreadsheet. No lock-in is deliberate: data you can't take with you isn't really yours.
