Japanese authorities said they would investigate fuel leaks on a 787 operated by Japan Airlines Co.
The, U.S. National Transportation Safety Board said it would analyse the lithium-ion battery and burned wire bundles from a fire aboard another JAL 787 at Boston's Logan Airport last week.
Several incidents in the past week have raised concerns about the 787 Dreamliner
The latest came Sunday at Tokyo's Narita International Airport, where Japan Airlines reported a "100-litre" (26 gallon) fuel leak during an inspection of one of its 787s. The leak came on the same Dreamliner that was hit by a previous fuel leak and onboard fire last week in Boston.
The series of Dreamliner glitches have prompted the Federal Aviation Administration to launch a safety review of Boeing's technologically advanced new-age aircraft.
The sophisticated new plane suffered a series of mishaps last week - two fuel leaks, the battery fire, a wiring problem, brake computer glitch and cracked cockpit window - increasing scrutiny on a plane that has a list price of $207 million.
"Looking at this from the point of view of average citizens, having these sort of incidents occur seemingly day after day, one could become very uneasy," Akihiro Ota told reporters at a ministry briefing on Tuesday. He said there was no deadline for reporting the outcome of the investigation, says Reuters.
"We plan to look into the scale of these accidents and what the overall situation is. We will convey the message to those who operate (the plane) that it is absolutely necessary to be safe," Ota said.
While many of the 787's mishaps are considered routine for a new design entering service, the daily toll has heightened concerns about the aircraft's safety. More than 800 of the planes have been ordered by airlines around the world.
Japan is the biggest market so far for the Dreamliner, with JAL and local rival All Nippon Airways Co flying 24 of the 50 Dreamliners delivered to date.
The most serious incident involving the 787 happened on Monday last week, when a fire broke out on a Dreamliner operated by JAL that had landed at Boston's Logan airport.
The following day, a different JAL 787, which was also at Logan airport, had to delay its flight to Tokyo for four hours after discovering a fuel leak emanating from the left wing.
JAL said this 787 then suffered a second fuel leak, also in the left wing, on Sunday during maintenance work at Tokyo's Narita airport, according to Financial Times.
The airline, which is co-operating with the investigation by Japanese regulators, said the two fuel leaks happened in different parts of the left wing, and that no conclusions had been reached in its own inquiries on the reasons for the incidents.
