Following three years of delays, Boeing has announced that its first 787 Dreamliner should be in service by September this year. A raft of problems has caused continual setbacks including design flaws, issues with supply and a fire which broke out during a test flight last November. Since the electrical fire caused the planemaker to temporarily suspend further tests Boeing has been reassessing the time frame for deliveries.

The announcement is likely to renew confidence in Boeing on the markets as it was originally feared the delivery date could be pushed back even further. According to Scott Fancher, Boeing’s vice-president, the revised delivery date will allow sufficient time for the manufacturer to test and install new software as well as new electrical systems.

Fancher added that Boeing had now taken into account the time it would take to make sure all the necessary testing of the 787 was completed as well as allowing some additional space for certification activities to be completed.

After the electrical fire forced an emergency landing, as well as the cessation of tests on 9 November, Boeing saw shares drop by just under 10 per cent. According to reports, four of its fleet of six test aircraft are back in the test programme. Shares have since regained some of their value and analysts are looking at the likely costs of compensation to airlines which have had their delivery dates pushed back.

Boeing has already received 847 orders for its Dreamliner and the first airline to fly a commercial service with the plane will be All Nippon Airways in Japan.
