Air India 787 Fuel Switch Cleared: No Abnormality Amidst Crash Probe

The Indian government has officially announced that a detailed examination conducted by aircraft manufacturer Boeing found no abnormality in the fuel control switch locking mechanism of an Air India Boeing 787 Dreamliner aircraft. This crucial development was shared by Minister of State for Civil Aviation Murlidhar Mohol in a parliamentary session on July 29, 2026. The announcement is a significant update relevant to two separate but related incidents involving Air India's Boeing 787 fleet. The primary context for this finding is the ongoing investigation into the devastating Air India flight AI-171 crash. On June 12, 2025, a Boeing 787-8 Dreamliner operating as flight AI-171 from Ahmedabad to London Gatwick tragically crashed shortly after takeoff, resulting in the deaths of 241 people on board and 19 on the ground, making it one of India's deadliest aviation accidents in recent years. A preliminary report released by the Aircraft Accident Investigation Bureau (AAIB) on July 12, 2025, indicated that the fuel control switches for both engines moved from the 'RUN' to the 'CUTOFF' position within a one-second interval shortly after liftoff, leading to an immediate loss of thrust and the subsequent crash. The cockpit voice recording from the crashed aircraft reportedly captured a pilot asking why the fuel supply had been cut off, with the other pilot denying having done so, raising questions about the cause of the switch movement, whether inadvertent or deliberate. The 'no abnormality' finding by Boeing specifically addresses the structural integrity and locking mechanism of the fuel control switches. While some reports initially linked this finding directly to the switch of the crashed AI-171 aircraft, others explicitly stated it pertained to a switch from a different Air India Boeing 787 (flight AI132) that was grounded in February 2026. In the February 2026 incident, a pilot reported a possible defect during a London-Bengaluru flight, noting that the left fuel control switch slipped from 'run' to 'cut off' when pushed slightly and did not lock in the selected position. This aircraft was subsequently grounded for precautionary checks. Regardless of whether the tested switch originated from the crashed aircraft or the grounded one, the finding that the *design and mechanical integrity* of this critical component shows no inherent flaw is a significant development in the broader investigation into the reliability of the Boeing 787 fuel system. The Directorate General of Civil Aviation (DGCA) had directed Boeing to carry out testing of the fuel control switch locking mechanism at the manufacturer's facility in Seattle as part of continued airworthiness checks. Minister Mohol further stated that while no abnormality was observed in the detailed examination of the fuel control switch, including its detent mechanisms, further inspection of the complete 'Thrust Control Module' at the original equipment manufacturer's facility is still underway. This suggests that while a direct mechanical defect in the switch itself has been ruled out, investigators are still exploring other potential factors that could have led to the fuel supply being cut off, including human factors, broader system interactions, or other components within the thrust control module. The investigation into the Air India AI-171 crash is in its final stages. The Supreme Court was informed in July 2026 that the Aircraft Accident Investigation Bureau (AAIB) is expected to submit its draft final report by October 2026. The AAIB had previously released an interim statement on June 12, 2026, indicating significant progress in the probe. This final report will provide a comprehensive account of all findings and contributing factors to the tragic accident. The news is of high importance for India's audience given the national airline and significant loss of life, but also has international implications for aviation safety, especially for the Boeing 787 fleet globally. Many global carriers, including Lufthansa, Singapore Airlines, and Japan Airlines, also performed precautionary switch inspections after the AI-171 crash, reporting no anomalies.
