Q: The U.S. Federal Aviation Administration is launching a comprehensive review of the critical systems of Boeing's 787, the aircraft maker's newest and most technologically advanced plane, after a fire and a fuel leak earlier this week, the agency said Friday. 
  
 The review will include the design, manufacture and assembly of those systems, the FAA said in a statement. Officials planned to detail the review at a news conference Friday morning. 
  
 The 787, which Boeing calls the "Dreamliner," relies more than any other modern airliner on electrical signals to help power nearly everything the plane does. It's also the first Boeing plane to use rechargeable lithium ion batteries, which charge faster and can be molded to space-saving shapes compared to other airplane batteries. The plane is made with lightweight composite materials instead of aluminum. 
  
 The FAA statement gave no indication that the agency intends to limit or prohibit the 787 from flying during the review. 
  
 A Boeing official said the company is working with the FAA. 
  
 "We are absolutely confident in the reliability and performance of the 787," Boeing spokesman Marc Birtel said. "We are working with the FAA and our customers to ensure we thoroughly understand any introductory issues that arise. While we take each issue seriously, nothing we've seen in service causes us to doubt the capabilities of the airplane." 
  
 A fire ignited Monday in the battery pack of an auxiliary power unit of a Japan Airlines 787 empty of passengers as the plane sat on the tarmac at Boston's Logan International Airport. It took firefighters 40 minutes to put out the blaze. A day later, a fuel leak delayed a flight from Boston to Tokyo of another Japan Airlines 787. 
  
 On Friday, Japan's All Nippon Airways reported two new cases of problems with the aircraft. ANA spokeswoman Ayumi Kunimatsu said a very small amount of oil was discovered leaking from the left engine of a 787 flight from southern Japan's Miyazaki airport to Tokyo. 
  
 The jet returned to Miyazaki, but after checks found no safety risk it flew to Tokyo. ANA said on another flight, to Matsuyama on the island of Shikoku, glass in a cockpit window cracked and the aircraft was grounded for repairs. 
  
 Boeing has insisted 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. 
  
 Boeing has delivered 50 of the 787s, starting in late 2011, and has orders for nearly 800 more. To get through the backlog, Boeing is increasing production to build 10 of the planes per month in Washington state and South Carolina by the end of the year. 
  
 By comparison, it builds more than one 737, Boeing's best seller, every day. 
  
 The company said in November that it had begun making five 787s per month. But if any major manufacturing changes are needed to fix the problems, it could fall further behind in deliveries.

 TOKYO/WASHINGTON Boeing Co's 787 Dreamliner jet suffered a cracked cockpit window and an oil leak on separate flights in Japan on Friday - the latest in a series of incidents to test confidence in the sophisticated new aircraft. 
  
 All Nippon Airways Co said a domestic flight from Tokyo landed safely at Matsuyama airport in western Japan after a crack developed on the cockpit windscreen, and the plane's return to Tokyo was cancelled. 
  
 The same airline later said oil was found leaking from an engine of a 787 Dreamliner after the plane landed at Miyazaki airport in southern Japan. An airline spokeswoman said that return flight to Tokyo's Haneda airport was also cancelled while the leak was investigated. No one was injured in either incident. 
  
 The Dreamliner, the world's first carbon-composite airliner, which has a list price of $207 million, has been beset by problems this week. 
  
 U.S. transportation officials will hold a press conference in Washington at 0930 EDT (1430 GMT) to discuss issues related to recent electrical problems on the new plane, one person familiar with the matter told Reuters. Bloomberg News said the U.S. Federal Aviation Administration would announce a review into the jet's power system at that news conference. 
  
 U.S. regulators have raised questions about the plane's reliability on long transocean routes, the Wall Street Journal reported. 
  
 The 787 Dreamliner made its first commercial flight in late-2011, after a series of production delays put deliveries more than three years behind schedule. By the end of last year, Boeing had sold 848 Dreamliners, and delivered 49. 
  
 Earlier this week, a battery fire caused damage to an empty 787 jet operated by Japan Airlines while it was on the ground at Boston airport. The next day, another JAL 787 spilled 40 gallons of fuel onto the taxiway at the same airport after a problem that caused a valve to open, forcing the plane to delay its departure. [ID:nL1E9CA4BU] On Wednesday, ANA cancelled a domestic Dreamliner flight due to a brake-control computer glitch. 
  
 Boeing's top Dreamliner engineer, Mike Sinnett, was rolled out midweek to defend the 787, saying the plane's problem rates were no higher than with Boeing's successful 777 jet. 
  
 SPIDER WEB CRACK 
  
 ANA said crew noticed a spider web-like crack in a window in front of the pilot's seat about 70 minutes into Friday's flight, which was close to its destination. 
  
 "Cracks appear a few times every year in other planes. We don't see this as a sign of a fundamental problem" with Boeing aircraft, a spokesman for the airline said. 
  
 On the later flight, the ANA spokeswoman said she could not specify how much oil leaked from the engine. 
  
 The latest incidents came just hours before ANA was due to launch its maiden service between Tokyo and San Jose, California with the Dreamliner. That flight was due to leave Tokyo at 0830 GMT, returning to Japan after an around 90-minute turnaround in the United States. 
  
 ANA and JAL together fly 24 of the 49 Dreamliners delivered to end-December. 
  
 In India - where state-owned Air India has taken delivery of six Dreamliner jets and has more on order - a senior official at the aviation regulator said there was concern at the recent spate of Dreamliner glitches. The Directorate General of Civil Aviation has not ordered any Dreamliner checks for now, but is waiting for a safety report from the U.S. National Transportation Safety Board, the official said. 
  
 Air India spokesman K. Swaminathan told Reuters that the airline's debut Dreamliner flight from India to Paris on Thursday went without a hitch. 
  
 FUEL SAVINGS 
  
 One of Boeing's chief innovations with the 787 is its use of electrical power to run on-board functions such as hydraulics and air conditioning, instead of relying on heavier pneumatic systems used on other planes. The weight savings make the 787 more fuel efficient, a big advantage for airlines battling high jet fuel costs. 
  
 To power the electrical system, the 787 uses generators attached to the plane's engines, which produce about 1.5 megawatts of power, enough to power about 300 hot water heaters. The system uses high-voltage distribution panels and powerful batteries, such as the one that caught fire in Boston on Monday. 
  
 Makoto Yoda, president of Japanese battery maker GS Yuasa Corp, which makes the Dreamliner batteries, said his company was looking into Monday's fire, and was sending a team of engineers to cooperate with the U.S. investigation.

A: 
Another day, another handful of reported problems with Boeing's 787 Dreamliner. This time, one jet landed in Japan with a cracked windshield and another developed a sizable oil leak at a different airport in the country, reports Reuters. Neither resulted in any injuries, just canceled flights. Aviation experts chalk up the mishaps—including ones of similar scope earlier in the week—to "teething problems" common to any new airliner's rollout, reports CNN. Still, US aviation officials will lay out details of a comprehensive review of the plane's mechanical systems today, reports AP. "We are absolutely confident in the reliability and performance of the 787," says a Boeing spokesman. "We are working with the FAA and our customers to ensure we thoroughly understand any introductory issues that arise."
