Lycoming Engine Maintenance Tracker

Lycoming's service ecosystem runs on SI-1009 (TBO schedule, with the 12-year calendar note), SB 480 (oil & filter intervals), and the cam/lifter corrosion vulnerability that makes regular flying the cheapest maintenance. Practically: the cam sits high in a Lycoming and rusts first when the engine sits — utilisation history is condition data for these engines. Those specifics define the recurring items on this board — they're the maker's own schedule rather than generic engine folklore, which is why the tracker is engine-line-specific instead of one-size-fits-all.

The maker's current service documents — service bulletins, instructions and the maintenance/overhaul manuals for your exact model and serial range — plus any program (135, CAMP-style) your operation runs under. Intervals shift with revisions, so confirm against the current document set and record the reference in each entry's notes; this board tracks your dates, while the documents own the rules.

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.

Yes — one click exports your complete engine service 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.
