Annual Inspection Scheduler

91.409(a): an annual inspection within the preceding 12 calendar months, by an IA, valid to the end of the month. The detail that catches Part 91 owners: the end-of-month rule means a March 3rd annual and a March 28th annual both expire March 31st next year. Encode the real next-due date here at every sign-off — including the end-of-month or interval-deduction quirks — and the badge carries the arithmetic from then on.

The aircraft (or the affected operation) is grounded as a matter of law until the inspection is completed — and operating anyway risks certificate action and voided insurance. There's no grace period in the rule; the grace period is whatever warning buffer you build, which is exactly what the amber badge is.

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 inspection schedule 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.
