Dreamliner jet grounded by Air India based on a pilot's report. The issue was reported on Sunday after the plane, which took off from London, landed in Indian's Bengaluru city. The regulator said that while starting the engine during take-off, the crew noticed that twice the fuel control switch - which regulates the flow of fuel into the plane's engines - did not "remain positively latched in the run position when light vertical pressure was applied". It remained stable the third time and the crew closely monitored the aircraft during the flight, which "was completed without incident".

Air India had said in a statement on Monday that it informed India's aviation regulator about the issue and that it was getting the pilot's concerns checked on a "priority basis". A Boeing spokesperson had told the BBC in response to a question that the company was supporting Air India's "review of this matter". The Directorate General of Civil Aviation (DGCA) said on Tuesday that when the switches were operated according to Boeing's recommended procedure, they were found to be "satisfactory", staying at run instead of moving to cut-off (which can stop fuel supply to the engines). It added, however, that incorrectly handling the switch caused it to "move easily from run to cut-off". These checks were performed in the presence of DGCA officials on the affected aircraft and another aircraft, the statement said. The DGCA has also asked Air India to circulate Boeing's recommended procedure to operate the switch to its crew members. The grounding of the plane gained a lot of attention as it came amid an ongoing investigation into last June's plane crash involving an Air India aircraft of the same model which killed 260 people.
