Propeller Overhaul Tracker
Track propeller overhaul limits per component — current hours vs limit with remaining-life badges per serial.
prop overhauls run on dual limits — hours (commonly 2,000–2,400) AND calendar (5–6 years for many Hartzell/McCauley models).

Free propeller overhaul tracker: every component with serial, current hours and limit, plus remaining-life badges that go amber at 10% left. the calendar limit almost always arrives first on privately flown aircraft, and prop hours diverge from tach time after any mid-life swap.
About Propeller Overhaul Tracker
The calendar limit almost always arrives first on privately flown aircraft, and prop hours diverge from tach time after any mid-life swap — that's the sentence this tracker exists to make harmless. Background: prop overhauls run on dual limits — hours (commonly 2,000–2,400) AND calendar (5–6 years for many Hartzell/McCauley models). Each entry pairs a serial with its current hours and limit; the badge shows remaining life and flips amber inside the final 10%, red at zero. It's the difference between component retirement as a planned line item and as an AOG discovery.

Frequently asked questions
Is the limit on propeller overhaul mandatory or advisory?+
Under Part 91, manufacturer intervals like this are largely advisory — you may operate on condition — but the advisory label hides real teeth: the calendar limit almost always arrives first on privately flown aircraft, and prop hours diverge from tach time after any mid-life swap. Insurance positions, 135 program requirements, resale value and plain risk management all push toward tracked compliance, and the tracking itself is nearly free. The expensive version is re-deriving component history at pre-buy time.
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.
Where is this data stored?+
Everything you enter is saved in your browser's local storage on your own device — nothing is uploaded to any server. Your records stay completely private, work offline, and load instantly. Use the CSV export regularly to keep an off-device backup copy.
Can I export these records for an audit?+
Yes — one click exports your complete component life 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.
