Boeing 787 under probe for overheated battery

[TOKYO] The case of a battery overheating aboard a Boeing 787 Dreamliner on Jan 14 has rekindled concerns about its safety.

The state-of-the-art 787s were temporarily grounded around the world last year due to a number of batteries overheating. As the latest incident caused only minor damage, Japan's Land, Infrastructure, Transport and Tourism Ministry has no intention of taking such measures as suspending operations.

Yet, the cause of the trouble is still unknown and the ministry has begun investigating the case in cooperation with other entities, including the US Federal Aviation Administration.
