The US aviation regulator FAA on 20 April 2013 approved resumption of normal air service of Air India's Dreamliner aircraft, operations by mid-May 2013.
It is important here to note that Air India's Dreamliner was grounded since January 2013 after battery fire incidents; The US Aviation regulator FAA had approved Boeing's revamped battery system for these new generation long-haul aircraft.
It was decided that a team of engineers from Boeing will be coming into India and they are likely to start work by 22 April 2013 to reset the new batteries on the six Dreamliners of Air India.
The US Federal Aviation Administration (FAA) permitted the new battery design made by the Japanese battery manufacturer and Boeing. It was only after the battery fire incidents, that the entire global fleet of 50 Boeing-787s, owned by eight airlines, including Air India, was grounded.
