Maintenance Due List Builder

Three mechanisms: batching (items done during already-open inspections skip their own setup/access costs), parts lead time (pre-ordered parts kill AOG days), and shop scheduling (a defined workscope gets quoted and slotted; 'look it over' gets billed hourly). Walking in with a categorised list — due now, due soon, batch-worthy, parts pre-ordered — routinely saves a double-digit percentage of the invoice and most of the calendar surprise.

Deliberately lighter: subscription platforms compute intervals from utilisation feeds and manage work orders; this board keeps the dates you already know in one visible, badge-watched place, free, in your browser. For a large 135 fleet you'll want the heavy tool. For everyone underneath that, the binding constraint is visibility rather than computation — and visibility is exactly what this provides at zero cost.

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 due-item board is never trapped here.
