(CNN) -- A Boeing 787 Dreamliner made an emergency landing in Japan early Wednesday morning after an alarm signal on a battery activated, a spokesman for All Nippon Airways said. The incident follows a string of recent mechanical and other problems associated with the 787.
The ANA flight, which was scheduled to leave Yamaguchi Ube Airport at 8 a.m. (6 p.m. ET Tuesday) and to arrive at Haneda Tokyo International Airport at 9:25 a.m., made an unscheduled landing in Takamatsu airport, Takuya Taniguchi said.
Boeing spokeswoman Lori Gunter said the company is "aware of the event and working with the customer."
The National Transportation Safety Board said it was aware of the latest incident and was gathering information.
Dreamliner troubles dating back four months include reports of an oil leak, a fuel leak, engine cracks and a damaged cockpit window. This follows a very difficult development history that included a series of production setbacks and other delays before the plane entered service in 2011.
