Rolls-Royce notes the termination by Airbus of an order for six Trent 900-powered Airbus A380 aircraft from Skymark Airlines of Japan. The aircraft were due for delivery between 2014 and 2015. The airline had also selected TotalCare service and support for the engines. This cancellation reduces the Group’s order book by £351m which represents 0.5% of the Group’s order book of £71.6bn as at 31 December 2013. Rolls-Royce announced on 15 September 2011 that Skymark had signed a letter of intent for the six Trent 900-powered aircraft. On 18 December 2012 Rolls-Royce announced that Skymark had signed a contract for Trent 900 engines with long-term TotalCare service support.
