About Engine Break-In Checklist
Checklists work because memory doesn't — especially for tasks performed annually or under pressure. For owners after overhaul or cylinder work, the specific trap: break-in has one enemy — glazing from heat without ring pressure — which is why babying a new engine is the way to ruin it. Every item here exists because someone, somewhere, learned it expensively. Progress saves in your browser, sections keep the sequence sensible, and one reset readies the list for the next use.

Frequently asked questions
Why must a fresh engine be run hard, not babied?+
Ring seating needs combustion pressure pushing the rings against fresh cylinder walls while honing marks still cut: high power supplies the pressure, and the rings and cylinders lap into seal. Run gently, the surfaces polish without seating — glazing — and the result is permanent oil consumption fixable only by re-honing. Manufacturer break-in procedures (mineral oil, sustained high power, varied settings, no long idles) all serve that one mechanism.
Should I adapt this checklist to my specific aircraft?+
Yes — treat it as the airworthy baseline and extend it: your model's known weak points, your shop's or kit maker's supplemental items, the quirks your aircraft has taught you. The structure (sectioned, ordered, ticked live) matters more than any single item, and a checklist that reflects YOUR aircraft gets used, which is the only metric that counts.
Why doesn't this tool sync to the cloud?+
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.
Can I export these records for an audit?+
Yes — one click exports your complete checklist record as a CSV file that opens in Excel, Google Sheets or Numbers. The export preserves every column exactly as entered, so you can print it, attach it to paperwork, or hand it to an inspector, buyer or insurance underwriter as a supporting summary alongside your official records.
