Description

This advisory circular (AC) describes the procedures that you, domestic design approval applicants and design approval holders (DAHs), should follow when entering into a certification data retention agreement with the Federal Aviation Administration (FAA). This AC also defines the type of certification data that constitute a government record.

If you are planning to use an electronic data storage system as your means of retention for your type design data, we recommend you follow the guidance outlined in AC 21-48, Using Electronic Modeling Systems as Primary Type Design Data. AC 21-48 describes an acceptable means for using electronic modeling systems in design, manufacturing, installation, and inspection processes. Although in that AC we define an “electronic modeling system” as a three-dimensional (3-D) modeling system, we encourage you to use the guidance provided because it identifies the criteria for using electronic type design data and includes requirements for how to access and present the data.

This AC is not mandatory and does not constitute a regulation, but if you elect to follow the means described in this AC, you must follow it in its entirety.
