Air India's hopes were strengthened after a meeting of officials aviation regulators of seven countries, including the Directorate General of Civil Aviation (DGCA) and the US Federal Aviation Administration, US Department of Transportation and Boeing in the US last week.
The meeting was informed that a "permanent fix" to the problem with the lithium-ion batteries was likely to be in place by March-end, the sources said.
Officials of the aviation regulators of India, Chile, Ethiopia, Japan, Poland, Qatar and the US, whose airlines have these next-generation airplanes in their fleet, attended the meeting with Boeing.
Once a solution is found and certified by the US FAA, it would take about a week to get the grounded Dreamliners ready to fly again, the sources said.
Raymond Conner, Executive Vice president of Boeing and head of its commercial aeroplanes division, was reported as saying that Boeing would not abandon the lithium-ion batteries used in these planes which are at the centre of a worldwide safety probe.
