This time, the problem involved a fuel leak. The plane lost approximately 40 gallons of jet fuel before being brought back into the gate for an inspection. While the plane eventually took off for Tokyo, the fuel leak was a reminder of the FAA airworthiness directive in December requiring airlines to check the fuel line connections on all Dreamliners.
Long-term damage to Boeing & the Dreamliner
This is not the first high profile problem involving the Dreamliner. Given its complexity and technological advancements, launching the 787 has been filled with delays and setbacks. (Read More: Is the Boeing 787 Dreamliner Truly a Game Changer?)
Now that the Dreamliner is in service with 46 delivered to airlines around the world, these latest problems are magnified. They also come as Boeing is in the midst of ramping up production of the Dreamliner. The company still has a backlog of more than 800 Dreamliner orders and so far there's no indication airlines have cancelled 787 orders because of the recent problems.
"There are many new technologies in this plane, so inevitably there will be many glitches," said Richard Aboulafia, an aviation consultant with the Teal Group in Washington, D.C. "But put the words 'fire' and 'new jetliner' together in a sentence and you're bound to scare travelers and airlines. Boeing will be able to make this situation right, but they need to act fast to avoid serious problems with customers."
