NEW DELHI: Air India has grounded a Boeing 787 Dreamliner aircraft after a pilot reported a potential malfunction involving the engine fuel control switch, a critical cockpit component that regulates fuel flow to the engines, aviation officials said. The precautionary action has drawn renewed attention to the system following a fatal aircraft accident near Ahmedabad on June 12 last year, where fuel control switches were among the elements examined by investigators.
According to airline officials, the issue was flagged during routine operations when the flight crew noticed abnormal behaviour of the fuel control switch during engine start procedures. The switch, which is designed to remain firmly locked in the “RUN” position once engaged, reportedly failed to stay in place and showed signs of moving toward the “CUTOFF” position. The aircraft landed safely and was subsequently removed from service for detailed inspection.
Air India said the aircraft was grounded immediately in line with established safety protocols and that engineering teams were assigned to carry out technical checks. The airline also informed aviation regulators and sought assistance from the aircraft manufacturer to assess the reported anomaly.
“The safety of passengers and crew is our highest priority,” an Air India official said. “The aircraft has been taken out of operation while the reported issue is examined thoroughly. Necessary coordination with the manufacturer and the regulator is underway.”
The fuel control switch plays a vital role in engine operation, controlling the supply of fuel during start, flight, and shutdown. Any unintended movement of the switch can interrupt fuel flow and affect engine performance. While such events are rare, aviation procedures require that even suspected irregularities be treated seriously.
Sources familiar with the matter said the pilot observed the issue during engine start checks, prompting the crew to log the fault and report it to maintenance teams. Engineers later confirmed that the aircraft would remain grounded until the switch mechanism and related systems are fully inspected and cleared.
The incident has attracted attention due to its timing, coming months after the June 12 crash near Ahmedabad that resulted in heavy loss of life. While investigators have not publicly established a final cause for that accident, the functioning of engine fuel systems, including fuel control switches, was among the technical aspects examined during the probe.
Aviation experts caution that the current grounding should not be linked directly to the Ahmedabad crash, stressing that every reported defect is assessed on its own merits. “This is a precautionary action based on a pilot report,” said an aviation safety specialist. “It reflects the layered safety culture of commercial aviation, where aircraft are withdrawn from service at the first sign of a potential problem.”
India’s aviation regulator has been informed of the grounding and is monitoring the situation. Officials said the regulator may review inspection findings once the airline and manufacturer complete their assessment. The regulator has, in the past, directed airlines to conduct fleet-wide inspections following serious incidents, depending on the nature and extent of any identified issue.
Air India operates a sizeable fleet of Boeing 787 Dreamliners on international and long-haul routes. Industry analysts said grounding a single aircraft is unlikely to significantly disrupt operations, though prolonged inspections or additional findings could require schedule adjustments.
The airline has previously stated that it complies with all airworthiness directives and maintenance advisories issued by regulators and manufacturers. Following last year’s accident, Air India had conducted precautionary checks on certain systems across its fleet as part of enhanced safety oversight.
Passengers on the affected flight were not inconvenienced beyond routine operational adjustments, officials said. The airline made alternate arrangements where required and ensured continuity of service.
The aircraft manufacturer has been notified of the reported issue and is expected to assist in evaluating the component. Manufacturers typically provide technical guidance, inspection procedures, or replacement recommendations if required after such reports.
Aviation engineers explained that fuel control switches are subject to regular inspection as part of scheduled maintenance, but pilot-reported issues often lead to more detailed examinations, including component removal, bench testing, and review of maintenance history.
The incident underscores the importance of pilot reporting systems, which form a cornerstone of global aviation safety. Crew members are trained to report even minor irregularities, allowing airlines and regulators to identify trends and address potential risks before they escalate.
A senior airline captain said such actions demonstrate the system working as intended. “Aircraft are complex machines. What matters is how quickly potential issues are identified and managed. Grounding an aircraft is always the safer choice when there is uncertainty.”
At this stage, Air India has not indicated whether similar inspections will be extended to other aircraft in its fleet. Officials said further action would depend on the outcome of the ongoing technical review.
The airline said it would provide updates as inspections progress and reiterated that passenger safety remains its primary concern.
