A: Boeing applied to the FAA to make the 787 in 2003. The first plane flew in December 2009, and six test planes ran up some 4,645 flight hours. The first paying passengers took flight in October 2011, more than three years behind schedule.
Q: Why the delays?
A: Parts for the jet are made by 52 suppliers scattered around the globe. And, in a first for Boeing, large sections of the jet are built by these outside vendors and then joined together. That process, aimed at saving money, wasn't as smooth as Boeing had hoped. Parts weren't delivered on time, and the quality of some suppliers' products was poor.
Q: How much does the plane cost?
A: The 787-800 has a list price of $206.8 million, but airlines often negotiate discounts.
Q: How many passengers can fit on the plane?
A: It is designed to carry 210 to 250 passengers. Configurations vary depending on how many business-class seats and how much coach legroom each airline wants to provide.
Q: How many 787s are there?
A: Boeing has delivered 50 planes so far. Another 798 are on order. The company is ramping up production to build 10 787s per month in Washington state and South Carolina by the end of the year.
Q: Is it normal for a new plane to have problems?
A: Any complicated piece of machinery has glitches at first. The Airbus A380, for instance, had an engine explode midflight in late 2010. However, the unique nature of the 787's construction — and the increased media spotlight on this plane — have regulators doing a more thorough review.
Boeing insists that the 787's problems are no worse than what it experienced when its 777 was new in the mid-1990s. That plane is now one of its top-sellers and is well-liked by airlines.
"Every new commercial aircraft has issues as it enters service," Ray Conner, president and CEO of Boeing's commercial aircraft division, said Friday at the FAA news conference.
Q: What airlines fly the 787?
A: Japan's All Nippon Airways is the largest operator of the plane. United is the first U.S. airline customer with six. Air India, Ethiopian Airlines, Japan Airlines, LAN Airlines, LOT Polish Airlines and Qatar Airways also fly the plane.
Q: Where in the U.S. does the plane fly?
A: United Airlines is the only U.S. carrier to fly the plane. It flies between Los Angles and Tokyo and between various hubs such as Newark, N.J., and Houston and between Los Angles and Houston.
All Nippon Airways flies from Seattle and San Jose, Calif., to Tokyo. Japan Airlines flies from Boston to Tokyo, and LAN flies from Los Angeles to Santiago, Chile. Ethiopian started flying the plane to Washington's Dulles International Airport in late September but put a different aircraft on that route in mid-December.
Q: What's at stake for Boeing?
A: Any more production delays could further upset the airlines that are eager to start flying the plane and cost Boeing millions of dollars in contractual penalties. If major changes are needed, the plane might weigh more, cutting its fuel efficiency. Orders could shift to the Airbus A350.
Q: What other problems could this mean for Boeing?
A: The 787's long range is one of its main selling points. The FAA limits how far twin-engine airplanes can fly so if the jet loses one engine, it can still fly long enough to make an emergency landing. The 787 already has approval for flights up to three hours away from any airport. Boeing wants to raise that to 5.5 hours, opening up routes across the Pacific. The FAA could now delay that approval.
Q: How is Boeing faring as a company? Is it making money? How's the stock price doing?
A: It's expected to report a 2012 profit later this month. Boeing reported a $1.39 billion profit for 2011, up from $1.16 billion in 2010. Almost half of its business is from defense.
Boeing shares fell $1.93, or 2.5 percent, to close Friday at $75.16. Over the past year, they've traded between $66.82 and $78.02. They've fallen 3.3 percent in the one week since the fire.
Q: What does Wall Street think?
A: Citi analyst Kevin Gursky has kept a "buy" rating on Boeing Co. stock. Over the long run, he says, faster production of the 787 and other planes should generate cash that benefits shareholders.
Soon after the fire, BB&T analyst Carter Leake cut his rating on Boeing to "hold." In an interview on Friday, he said he expects Boeing to fix any problems with the 787, but that investors can benefit from growth in the aerospace industry by owning shares in other companies.
Q: What are passengers saying?
Passengers flying the 787 don't appear to be worried about safety, saying they expect a new plane to have some issues.
In Seattle, Adam Welch was excited for his first flight on a Dreamliner. He heard the news about the FAA's review and "was just hoping they didn't ground the plane I was supposed to fly on." As for the 787's problems, he said the plane has been experiencing "growing pains."
Donald Crump from Auburn, N.H., was at Boston's Logan International Airport Friday, checking in for his third 787 flight. He called the plane's problems "minor" and said the FAA review was "the politically correct thing to do." Crump likes the 787 because the well-lit and climate-controlled cabin provides passengers "a much more pleasing environment to travel in."
