What are the individuals known as who are designated by the Administrator to develop and approve technical data for aircraft?

Individuals designated by the Administrator to develop and approve technical data for aircraft are known as Designated Engineering Representatives (DERs). DERs play a critical role in the certification process by ensuring that aircraft designs comply with applicable regulations and standards. They have the authority to represent the Federal Aviation Administration (FAA) and are involved in evaluating technical data, providing recommendations on the airworthiness of aircraft, and approving modifications and repairs.

The designation process for DERs is part of the FAA’s efforts to ensure safety and compliance in aviation by leveraging expertise within the industry. These representatives are typically experienced engineers with specialized knowledge in specific areas such as structures, propulsion, or systems.

The other categories of designations, such as designated aircraft maintenance inspectors or designated airworthiness representatives, serve different functions within the aviation regulatory framework. While they also contribute to aircraft safety and compliance, they do not focus primarily on the development and approval of technical data, which is the specific responsibility of DERs. This specialization ensures that critical technical decisions are made by qualified individuals who have the necessary expertise to evaluate complex engineering data.
