Track every modification on your aircraft

Most piston aircraft accumulate STCs over their lifetime — an engine monitor here, a tip tank modification there, an autopilot upgrade, a speed kit. Each one changes your aircraft's type design and can affect which ADs and service bulletins apply. AircraftMX lets you search the FAA's full STC database, track what's installed, and keep the compliance ripple effects organized.

Search STCs by number, holder name, aircraft model, or keyword to find the exact modification you're looking for. When you add an STC to your aircraft, AircraftMX records the STC number, holder, description, aircraft models it applies to, and any related documentation. Mark each STC as installed on your specific aircraft to build a complete modification history.

The real power is in the connections. Installed STCs link to your equipment records — because an STC typically adds or modifies components — and to related service bulletins and ADs that may apply specifically because of that modification. When you install a new STC, AircraftMX helps you identify new compliance requirements that come with it, so you don't discover them at annual time.

The STC list gives you a full view of every modification tracked for your aircraft, with details on the holder, description, and installation status. For a comprehensive understanding of your aircraft's configuration, STC records work alongside equipment, ADs, and SBs to paint a complete picture of what's been modified, what compliance obligations those modifications create, and whether you're current.

For pre-buy evaluations, insurance documentation, or annual prep, a well-maintained STC record demonstrates that you understand your aircraft's configuration and manage it responsibly. It's the kind of documentation that builds confidence — for you, your mechanic, and anyone else who needs to understand what makes your airplane unique.
