All Nippon Airways said a domestic flight from Tokyo landed safely at Matsuyama airport in western Japan after a crack developed on the cockpit windscreen, and the planes 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 Tokyos Haneda airport was also cancelled while the leak was investigated. No one was injured in either incident.
The Dreamliner, the worlds first carbon-composite airliner, which has a list price of $207 million, has been beset by problems this week.
US 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 said. Bloomberg News said the US Federal Aviation Administration would announce a review into the jets power system at that news conference. US regulators have raised questions about the planes 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. On Wednesday, ANA cancelled a domestic Dreamliner flight due to a brake-control computer glitch.
Boeings top Dreamliner engineer, Mike Sinnett, was rolled out midweek to defend the 787, saying the planes problem rates were no higher than with Boeings successful 777 jet.
India concerned about Dreamliner glitches
India is concerned about the recent glitches in Boeings 787 Dreamliner jets and is awaiting a safety report by the National Transportation Safety Board, a senior government official said. The Dreamliner jet had three technical mishaps in as many days this month, including an electrical fire that caused severe damage to a plane. US transportation authorities are launching a review of the Dreamliner, a source familiar with the matter said on Thursday. State-controlled Air India has ordered 27 Dreamliners.
