The Director General of Civil Aviation (DGCA) on Monday launched an investigation into the 'uncommanded' mid-air deployment of the emergency turbine on Air India plane, Ram Air Turbine, which is usually used in case of engine failures.
"Boeing recommended maintenance actions for uncommanded RAT deployment have been carried out and no discrepancy has been observed. Aircraft is being released for service," the DGCA said in a statement.
In a statement on Sunday, an Air India spokesperson said the operating crew of flight AI117 from Amritsar to Birmingham on October 4 detected deployment of RAT of the aircraft during its final approach.
