Air India on 17 January 2013 grounded the fleet of all six Boeing 787 dreamliners after US federal agency asked its airlines to ground the Boeing 787 due to safety hazard.
The move for grounding the fleet came with decision made by the Directorate General of Civil Aviation (DGCA) who received a communication from the US watchdog Federal Aviation Administration (FAA) pointing to problems with the battery on the aircraft.
The US Federal Aviation Authority (FAA) conducted an investigation of an in-flight Boeing 787 battery incident in Japan on 16 January 2013 which posed a question on a potential battery fire risk in the 787. In response to that Japan had grounded 24 Dreamliner owned by two of its airlines - ANA (All Nippon Airways) and Japan Airlines.
As per Federal Aviation Authority (FAA), now it is made mandatory that before further flight, of Boeing 787 aircraft, it must go for a demonstration to the Federal Aviation Administration (FAA) to show that the batteries are safe.
The failure of battery resulted in release of flammable electrolytes, heat damage, and smoke on two Model 787 airplanes. The root cause of these failures is currently under investigation.The prevailing condition if not rectified could result in damage to critical systems and structures, and the potential for fire in the electrical compartment.
The FAA lately announced a comprehensive review of the 787's critical systems with the possibility of further action pending new data and information.
In addition to the continuing review of the aircraft's design, manufacture and assembly, the agency also will validate that 787 batteries and the battery system on the aircraft are in compliance with the special condition the agency issued as part of the aircrafts certification.
In September 2012, Air India had also experienced a fault in its Dreamliner's liquid cooling system and electrical power system, which had led to the grounding of all three of these planes at that time. After the faults were rectified, these aircraft have been flying regularly on select domestic and international routes.
