How to Identify and Source Avionics Parts

Avionics parts encompass the electronic systems that provide navigation, communication, flight instrumentation, and monitoring functions in an aircraft. Selecting the correct component requires confirming the exact manufacturer part number, verifying applicable aircraft model and configuration, and ensuring the required certification documents such as the Illustrated Parts Catalog (IPC) are available. American Aviation Parts provides a searchable database to streamline this process.

Tools and Materials

• Manufacturer part number list or database
• Illustrated Parts Catalog (IPC) for the aircraft
• Aircraft Maintenance Manual (AMM) or Service Manual
• Verification checklist
• Computer with internet access
• Safety glasses

Step-by-Step Process

1. Gather Aircraft Information

   Record the aircraft model, serial number, installed equipment, and any applicable STCs or modifications. This data is the foundation for all subsequent verification steps.

2. Locate Manufacturer Part Number

   Use the aircraft IPC or an online database to find the exact part number. For electronic components, browse the Avionics category to see related listings.

3. Verify Certification Documentation

   Confirm that the part is accompanied by the required documentation—such as an FAA Form 8130‑3, PMA approval, or a Manufacturer Authorization. See the Manufacturer Authorizations page for guidance.

4. Confirm Compatibility with Aircraft Configuration

   Check that the part matches the aircraft’s installed systems. For navigation and surveillance equipment, review the ADS-B and Antennas categories to verify connector types and frequency compatibility.

5. Source the Part from a Trusted Supplier

   When the part number is confirmed, order from a reputable source. American Aviation Parts can supply the verified component with proper paperwork. Example products include the Yaesu FTA-550L 5W Portable Airband Nav/Com Transceiver and the Guardian Instrument Panel Flush Mount For Ipad Mini Ifdr-Pm-Ipami Ipad mini 1 to 5 All Generations 52-18 Smart Panel Mount.

6. Review Condition and Return Policies

   Determine whether the part is new, serviceable, or overhauled, and read the Return Policy to understand inspection rights.

7. Complete Purchase and Arrange Delivery

   Finalize the order and coordinate shipping. Review the Shipping and Delivery Information page for lead times and documentation requirements. If any questions remain, contact American Aviation Parts for assistance.
