What's Happening?
The Directorate General of Civil Aviation (DGCA) has initiated a thorough investigation into a technical issue involving an Air India Boeing 787 Dreamliner at London Heathrow. The aircraft, identified
as VT-ANX, was grounded after its left engine fuel control switch slipped from the 'Run' to 'Cutoff' position during engine start-up. This incident occurred on February 2, 2026, as flight AI-132 was preparing to depart for Bengaluru. The malfunction was noted in the pilot's log, indicating a failure of the switch to remain locked. This discovery is significant as it follows previous fleet-wide inspections by Air India after a similar issue was linked to a crash in Ahmedabad last year. The recurrence of this defect suggests a potential systemic mechanical or design flaw that may have been overlooked in earlier checks.
Why It's Important?
The malfunction at Heathrow could have significant implications for the ongoing investigation into the crash of Flight AI-171, which occurred on June 12, 2025, shortly after takeoff from Ahmedabad, resulting in 260 fatalities. The crash was initially attributed to pilot error or intentional interference, as cockpit recordings captured a conversation about the fuel being cut off. However, the documented failure of the fuel switch to lock on VT-ANX provides evidence that these switches can move 'uncommanded', potentially shifting the focus of the Aircraft Accident Investigation Bureau (AAIB) from pilot error to a mechanical failure. This development could influence aviation safety protocols and regulatory scrutiny, particularly concerning Boeing aircraft.
What's Next?
The grounding of the Dreamliner at Heathrow coincides with a diplomatic mission by India's External Affairs Minister S Jaishankar in the United States, focusing on supply chain resilience and strategic cooperation. The recurring safety issues with Boeing aircraft could become a topic of discussion in Indo-US trade and aviation safety dialogues. The DGCA's investigation will likely explore whether the defect is isolated or indicative of a broader issue within the Dreamliner fleet. The outcome could lead to further inspections, design reviews, or regulatory changes to enhance aircraft safety.
