Approved Model List STC

AML STC

Section 03: Certification & Approval Types

Definition

A Supplemental Type Certificate that includes an Approved Model List, which specifies multiple aircraft models on which the modification may be installed. An AML STC enables a single design approval to cover installation of a modification (typically avionics equipment or interior modifications) across many different aircraft types, rather than requiring separate STCs for each aircraft model. The STC holder demonstrates compatibility with each aircraft model listed on the AML.

Where This Shows Up

AML STCs are particularly common for avionics equipment upgrades (e.g., GPS navigators, ADS-B transponders, EFB solutions) where the same equipment can be installed in many different aircraft types. The AML can be expanded to add new aircraft models after the initial STC issuance.
