Frequently Asked Questions

No. Every GA MX Helper product is a one-time purchase: you pay once and it’s yours. There’s no monthly or yearly fee, no renewal, no account to keep active and nothing to cancel. The version you buy keeps working for as long as you use it, even with no internet connection. The add-ons and GA Wire Helper are optional one-time purchases too.

No. Unzip the download and double-click the GA MX Helper icon (there's one for Mac and one for Windows) — it opens the app in your web browser. Nothing to install, no account to create, no login screen. Chrome or Edge is recommended, since they can save your records to a real folder on your computer.

Yes, and Linux too. If it runs a modern browser, it runs GA MX Helper. It also works on tablets, though it's built and tested primarily for laptop/desktop use.

No. Everything core to the app — aircraft records, work orders, inventory, invoicing, checklists — works completely offline. A handful of optional features reach out to the internet when it's available (airport weather lookups, a general FAA AD awareness check on the Status page), and every one fails gracefully with no connection.

Nowhere but your own computer. There's no server behind this app — your aircraft records, customer information, and everything else stays either in your browser's local storage or in a folder on your own computer that you choose to connect. Nothing is transmitted anywhere.

Whatever wasn't backed up is gone — same as any file on your computer. This is exactly why the app supports connecting a backup folder (Settings → Data Storage): once connected, every change is also written there automatically.

Copy the app file and your data folder (if you're using one) to the new machine, and open it there. If you're using browser-only storage, export your data first (Import/Export) and import it on the new computer.

Go to Settings → Data Storage → "Offline FAA AD Database" and download the current AD dataset from the FAA's DRS site (a link is right there). Bring that file back and select it — the .zip DRS gives you works directly, and so does the .accdb inside it or a .csv/.xlsx if that's what you have. No conversion, no separate database software, and nothing is uploaded anywhere.

Not simultaneously on the same file — it's built around one file being the single source of truth at any given moment. Multiple technicians can absolutely use the same installation though — add each one under Settings → Employees & Permissions, and everyone signs their own work with their own PIN.

See the Pricing page for current cost. No subscription, no expiration — the version you buy keeps working for as long as you use it.

Bug fixes are automatic and free, no matter when you bought the app. A genuinely new capability is different — right now that's Engine Analytics and the Flight Data Add-On — and is sold separately, either bundled from the start or as a standalone upgrade. You'll always be able to keep using the exact version you already have.

An optional feature for tracking engine trends over time — CHT, EGT, oil temperature and pressure, RPM, fuel flow, and more — typed in by hand or imported from a CSV your engine monitor exports. It builds trend charts automatically. Available bundled with the base app or as a separate upgrade — see Pricing.

Yes. Buy the Engine Analytics Upgrade separately and you'll get a new license key by email — enter it under Settings → Product Updates and it unlocks immediately.

An optional set of pilot-facing features: a printable Flight Checklist booklet (with automatic Weight & Balance, V-speed and airport-frequency boxes and a logged revision history), a library of Temporary Placards, Performance Data tables and charts straight from your aircraft's POH/AFM, an airport frequency directory, and the Go Flying E6B calculator with density altitude. See the Features page for the full breakdown.

Yes, the same way Engine Analytics works: buy the upgrade separately, enter the license key you're emailed under Settings → Product Updates, and it unlocks immediately.

Because it's a digital product delivered immediately, and a one-time purchase rather than a subscription, sales are final — we don't offer refunds. If something isn't working right for you, contact us first.

Three ways: the banner at the top of this website always states the current version; the Changelog shows exactly what's shipped in each release; and you'll get an email whenever a new bug fix or update version is released.

No. GA MX Helper is a recordkeeping and shop-management tool — it helps you track, organize, and generate the paperwork you already produce, but it isn't an FAA system and doesn't substitute for your aircraft's official maintenance records. The exceptions are FAA Form 337 and Form 8010-4, which the app can fill as real, submittable government PDFs.

Independent A&Ps and traveling mechanics first and foremost — someone doing side work out of a hangar, or never in the same shop twice. It scales past that too if your work grows.

Yes — the Live Demo runs the real app right in your browser with sample aircraft, work orders, inventory and invoices, every feature unlocked. It's view-only, so nothing you change is saved. The Features page covers the rest.

A separate companion app for drawing aircraft wiring diagrams. You draw the schematic and it builds the wire list, pinouts, parts list, load analysis and wire labels from it. See GA Wire Helper for the full picture.

No. Each app works completely on its own and is sold separately. If you own both and link them, wiring diagrams are filed with each aircraft and show up in a Wiring Diagrams tab on that aircraft's profile in GA MX Helper.

No. It only reads your aircraft list, equipment and company info. Its own projects and PDFs are saved in a separate Wiring Diagrams folder next to GA MX Helper's data.

No — each app has its own key. The one exception is the Complete Bundle, whose single key unlocks both apps and both add-ons.
