NEW DELHI: Air India's Dreamliner aircraft, grounded since January after battery fire incidents, may resume normal operations by mid-May with the US aviation regulator FAA approving Boeing's revamped battery system for these new generation long-haul aircraft. “A team of engineers from Boeing is being flown into India and they are likely to start work by Monday to reset the new batteries on the six Dreamliners of Air India. They will work 24X7,” DGCA chief Arun Mishra told PTI. Engineers of the Directorate General of Civil Aviation and Air India would be working with the Boeing team in Mumbai. They are expected to hand over all the six Boeing-787s by the first week of next month, he said. BN
