India’s civil aviation regulator has ruled out a systemic defect in the fuel control switches on Boeing 787 Dreamliners after one of Air India’s aircraft was grounded earlier this week amid safety concerns, authorities said.
The action followed a pilot report that a fuel control switch failed to latch properly during routine checks before a long-haul flight from London to India, raising fresh scrutiny of a component central to a deadly June 2025 crash.
The Directorate General of Civil Aviation (DGCA) said Tuesday that its inspection of the grounded Boeing 787-8 revealed that the fuel control switch lock mechanism met design specifications and worked as intended when operated according to procedures. Separate statements from Air India confirmed that a subsequent fleet-wide re-inspection of fuel switches found no defects.
The incident occured February 1, 2026, when a 787-8 operating as Air India Flight AI132 from London Heathrow to Bengaluru experienced an abnormal condition during the engine start-up check. According to the airline, pilots observed that one of the left-engine fuel control switches did not remain securely in the “RUN” position when light downward pressure was applied, moving toward “CUTOFF” twice before setting properly on a third attempt. The aircraft completed its flight but was grounded in Bengaluru for inspection.
Fuel control switches on Boeing 787 aircraft are designed with a protective lock that requires an upward lift action before movement between the “RUN” and “CUTOFF” positions, a safeguard intended to prevent inadvertent fuel shutoffs in flight. DGCA officials said the observed behavior was consistent with crews not applying the precise movement sequence specified in the manufacturer’s procedures, rather than a mechanical fault in the switch assembly itself. The regulator has advised the airline to reinforce proper operating techniques for flight crews.
The grounding drew attention because fuel switch movement was also a key focus of the investigation into the June 12, 2025 crash of Air India Flight 171, a Boeing 787-8 that crashed into a building near Ahmedabad shortly after takeoff, killing 260 people including passengers, crew members and those on the ground. Preliminary reports from India’s Aircraft Accident Investigation Bureau indicated that both of that aircraft’s fuel control switches transitioned from “RUN” to “CUTOFF” shortly after liftoff, starving the engines of fuel and leading to a catastrophic loss of thrust.
Air India operates more than 30 Dreamliners, all of which have undergone precautionary fuel switch inspections. The airline noted that no anomalies were found and reaffirmed its commitment to safety. Boeing said it was working closely with Air India and supporting the review.
