Despite more than a decade to work out problems and an estimated $20 billion to build it, Boeing's 787 aircraft is still plagued by issues.
The high-tech, fuel-efficient airplane was supposed to be a game changer in the aviation industry — and it still may be — but it keeps making headlines for all the wrong reasons.
Ever since 787s finally began flying in 2011, there have been technical and mechanical problems, from software bugs and engine defects, to faulty wiring, trouble with hydraulics and fuel tank leaks.
"The lingering problems run the gamut from insignificant to highly significant. And it's a roll of the dice at this point, what the next one's going to be," says aviation writer Christine Negroni, who has covered the issues on her blog, Flying Lessons.
The biggest problem was with the planes' lithium ion batteries, which caught fire on two of the aircraft a year ago, leading regulators to ground the entire 787 fleet worldwide for more than three months.
