London: A set of fixes to the battery of the Boeing 787 Dreamliner have been approved by the US aviation authority, paving the way for the aircraft to resume flights.
The Federal Aviation Administration (FAA) approved Boeing's plan, which it said requires it to ‘conduct extensive testing and analysis’.
The FAA has also approved limited test flights for two aircraft to test the changes in the batteries, the BBC reports.
All 50 Dreamliners in operation were grounded after its lithium ion batteries emitted smoke in several separate incidents.
The plane is the first plane in the world to use the lithium ion batteries, which are lighter, hold more power and recharge more quickly.
Several planes owned by Japanese airlines had problems, including a cracked cockpit window, a fuel leak and one made an emergency landing after a smoke alert went off.
On 7 January, a fire started in a lithium ion battery pack of a Japan Airlines 787 in Boston, which prompted this round of US regulator checks and plane groundings.
