What is Part 21 Subpart J – Design Organisation Approval?
Part 21 Subpart J details the elements required of a design organisation in order to hold a CAA/EASA Design Organisation Approval (DOA). It outlines the requirements and procedures for the design, production, and approval of parts, appliances, and materials used in aviation. Subpart J sets forth the responsibilities of manufacturers, suppliers, and applicants seeking approval for the production of aviation products, including the need to demonstrate compliance with applicable design and airworthiness standards. The regulation encompasses aspects such as design data, quality systems, production control, and conformity assessment procedures. Compliance with Part 21 Subpart J ensures that aviation components meet the necessary safety and performance standards, contributing to the overall airworthiness of aircraft and the safety of flight operations.
Course Overview
This course provides delegates with an understanding of the UK Civil Aviation Authority (CAA) and the European Aviation Safety Agency (EASA) Part 21 Subpart J and the associated topics concerning the changes to Type Design, Supplementary Type Certificates (STC) (modifications) and repairs.
Our Singapore courses are delivered in cooperation with the Singapore Aviation Academy. Please visit the SAA website for upcoming dates.
