Japanese aviation authorities on Monday began two days of ground-based battery tests on a troubled 787 Dreamliner at an airport in western Japan, officials said.
Four officials from the Japan Transport Safety Board (JTSB) started checking the battery system of the All Nippon Airways airplane that has been grounded at Takamatsu airport for nearly three months.
The aircraft was forced to make an emergency landing in January after instruments indicated there was smoke coming out of the battery. That incident was instrumental in the worldwide grounding of all Boeing Dreamliner jets.
An official from the JTSB said a battery identical to the one that encountered problems had been put into the aircraft and was being examined.
"We will decide on what to do next after we finish analysing the data," the official said, adding that it was still unknown when the safety board will give the go ahead to resume flights.
The test came after Boeing in the United States conducted a 787 Dreamliner test flight Friday to assess a proposed battery fix that it hopes will get the grounded jetliner back in the skies.
