Manufacturing Methodology of an Aviation-Grade Part: Part 21 Certification

Abstract

Although there have been economic recessions, growth in the aviation industry steadily continuous. Even during Covid days. On April 17th 2020 The International Air Transport Association (IATA) released a report regarding air travel expectation which is shown in Figure 1. Hopefully air traffic will increase through Q3 and Q4 2020.

As we look at the manufacturing side of the aviation industry, it is worth emphasizing that yearly based aircraft manufacturing also increases. The main players such as Boeing, Airbus, Embraer, Bombardier, Comac, ATR, etc. share the commercial aircraft manufacturing market. Amongst those manufacturers, as it is shown in Figure 2, Boeing and Airbus have 81% of all commercial aircraft which have been manufactured from 2008-2018 according to IATA reports (IATA, 2019). The remain, 19% is shared by the others.

The aviation industry will execute on strategies to recover as quickly as possible. During the recovery phase, there will be many applications based on manufacturing technologies. More likely, new sterilization mechanisms will be implemented inside the cabin, cockpit and cargo bay and disinfection systems will be added to the environmental control system (ECS). In order to ensure successful implementation of new systems, design assurance flow should be followed. In the aviation industry, it is known that the manufacturing ofaviation-grade parts is clearly defined. The components of the system and the relation between steps are provided in Figure 3 as a flow chart.
