This research service is similar to the study on defence contractors with the focus now on commercial aerospace. Data is given for the 2005–2014 period, while analysis provided goes beyond these 10 years. New companies have been added to better reflect the commercial aerospace market participants. Companies with a diverse range of specialties have been covered such as the main OEMs, the prime engine manufacturers, and avionics and aerostructure suppliers. The study also highlights the relationships and partnerships between some of the market participants and provides insights on the impact of the cost reduction plans within the supply chain. In addition, a brief analysis of the deliveries and orders has been provided for air transport, regional, and business jet aircraft.
