Airworthiness Considerations of Supply Chain Management from Boeing 787 Dreamliner Battery Issue

With the globalization of the economy, the aviation market competition intensifies and the aviation product development mode has correspondingly changed. The aircraft manufacturers pack more and more works to the suppliers to join the development work. The role of suppliers becomes more and more important during the development. Therefore, the problems of suppliers are following which have a significant influence on the aircraft design, manufacture and EIS which is means through the whole lifecycle of the aircraft. On January 16, 2013, an ANA flight made an emergency landing in western Japan after a cockpit message warned of battery problems and a burning smell was detected in the cockpit and cabin. At the same time, the FAA issued an emergency airworthiness directive ordering all U.S.-based airlines to ground their Boeing 787s until yet-to-be-determined modifications are made to the electrical system to reduce the risk of the battery overheating or catching fire. This is the first time that the FAA has grounded an airliner type since 1979. This event caused that Boeing shares has fell 2.6%. It is not the only accident of Boeing 787. Similarly, for other aircraft types, such as the Airbus A380, had to delay delivery due to supplier problem. It can be conclude that the supply chain management has an important impact on the aircraft development. From the perspective of airworthiness, this paper analyze the suppliers management of Boeing 787 Dreamliner battery issue and some advices are given to provide references and learnt lessons to the aircraft industry. The main content of this paper is as follows: First of all, the context and the purposes of this study was introduced in Chapter 1; the airworthiness regulation of CAAC, FAA and EASA about applicants’ supplier management are introduced. All requirements covering supplier managements would be concluded. Secondly, this paper focus on the whole process and solution of Boeing 787 battery issue and analyze the airworthiness problem of supplier management. Boeing 787 uses the lithium-ion battery which was produced by Yuasa and assembled by Thales who are integrate it into avionic system. Thales is the tie 1 supplier and Yuasa is the tie 2 supplier. This paper will introduce the whole process and the final resolution given by Boeing. Based on the airworthiness regulation, the airworthiness problem of supplier management reflected from Boeing 787 battery issue would be analyzed, especially in the tie 2 supplier management show compliance with the airworthiness requirements. Thirdly, on the basis of precious analysis, the actual airworthiness regulation would be concluded and supplier management of some international company would be presented as example. It is shown that development mode change has brought more problems of supplier management. Finally, this paper proposes how to fully meet the airworthiness requirements to suppliers management. Some ideas and suggestions are given to avoid the similar events and support aviation industry
