Life-Limited Parts Tracker
Track life-limited parts limits per component — current cycles vs limit with remaining-life badges per serial.
life-limited parts have mandatory retirement times set in the type certificate data — exceeding them isn't deferred maintenance, it's an unairworthy aircraft.

Free life-limited parts tracker: every component with serial, current cycles and limit, plus remaining-life badges that go amber at 10% left. the back-to-birth trace requirement means a part without complete history is treated as expired regardless of its actual hours.
About Life-Limited Parts Tracker
life-limited parts have mandatory retirement times set in the type certificate data — exceeding them isn't deferred maintenance, it's an unairworthy aircraft. The trap is the second clock: the back-to-birth trace requirement means a part without complete history is treated as expired regardless of its actual hours. This tracker keeps each component as its own row — part, serial, current cycles, limit — and computes remaining life continuously, going amber at the last 10%. Update the current figures when you update your aircraft times and the board stays honest; export the CSV and your overhaul budgeting, pre-buy responses and annual planning all start from the same reconciled numbers.
How to use Life-Limited Parts Tracker
- 1Add each component with serial, current cycles and its limit.
- 2Update current figures whenever aircraft times update.
- 3Plan overhauls and budgets off the remaining-life badges; export as needed.
Why use Life-Limited Parts Tracker?
- ✓Per-serial rows: part, serial, current cycles, limit
- ✓Remaining-life badge per component — amber at 10%, red at zero
- ✓Encodes the real-world trap: the back-to-birth trace requirement means a part without complete history is treated as expired regardless of its actual hours

- ✓CSV export feeds budgets, pre-buys and annuals
Frequently asked questions
Is the limit on life-limited parts mandatory or advisory?+
Mandatory — retirement lives in the airworthiness limitations section are regulatory, and operating past them makes the aircraft unairworthy outright. There's no Part 91 latitude here as there is with TBO. That's also why the back-to-birth paper trail matters: a component whose history can't prove its accumulated time is treated as life-expired, whatever its true state.
How do I establish current times for components with patchy records?+
Anchor each component to its last documented event — overhaul release tag, 8130-3, installation logbook entry — and accrue forward from the aircraft times since that date. Where no anchor exists, the conservative convention is to assume the worst (time-expired or unknown-since-new) and price decisions accordingly. Enter your best-evidenced figure here with the anchor noted in the notes field; a documented assumption beats an optimistic blank.
Is this tool private — who can see my entries?+
Only you. Entries live in your browser's local storage and never leave your device, so there is no account, no cloud sync and no one else with access. Because the data is device-local, export a CSV backup before clearing browser data or switching computers.
How do I back up or print these records?+
Use the Export CSV button below the table: it downloads your full component life record as a spreadsheet-ready file. From there you can print a clean copy, archive it with your records folder, or import it into any other system. Exporting monthly is a good habit since the working data lives only in your browser.
