The reliability of Boeing's pioneering 787 Dreamliner jet is improving but is still not satisfactory, Mike Fleming, Boeing's vice president for 787 support and services said on Friday.
The Dreamliner's reliability rate is now around 98 percent, meaning that two out of every 100 flights is delayed, which is above the 97 percent reported in October but still short of the firm's target, Fleming told a news conference in Oslo where Norwegian Air Shuttle ASA , one of his most troubled customers, is based.
"I'll tell you that's not where we want the airplane to be, we're not satisfied with that reliability level of the airplane," Fleming said. "The 777 today flies at 99.4 percent ... and that's the benchmark that the 787 needs to attain.
The Dreamliner was supposed to be a game-changer for the aviation industry as its lighter body and sophisticated engines cut fuel consumption by 20 percent.
But it has been beset by problems including a battery fire that grounded all 787s in service for three months last year and forced Boeing to re-design the innovative lithium-ion battery and enclose it in a stainless steel containment box capable of withstanding an explosion.
