The government has said that Boeing's detailed examination of the Dreamliner aircraft's fuel control switch locking mechanism did not find any abnormality following an Air India pilot flagging possible issues with the system after operating a London Heathrow-Bengaluru flight in February this year. On February 2, an Air India pilot reported a defect in the fuel control switch of the Boeing 787-8 plane after operating the AI132 flight. The airline had grounded the aircraft for checks after it landed in Bengaluru from London. Following the incident, the Directorate General of Civil Aviation (DGCA), as part of continued airworthiness, directed Boeing to carry out the test of the fuel control switch locking mechanism. In a written reply to the Rajya Sabha on Monday (July 27, 2026), Minister of State for Civil Aviation Murlidhar Mohol said the DGCA, as part of continued airworthiness, had directed Original Equipment Manufacturer (OEM) level testing of the fuel control switch locking mechanism in Seattle.
"Detailed examination of Fuel Control Switch, including structural integrity of Fuel Control Switch detents, was carried out and no abnormality was observed. However, further inspection of the complete 'Thrust Control Module' at the OEM facility is underway," the Minister said in the written reply. The Minister was responding to a question about the outcome of DGCA's OEM-level testing of the fuel control switch locking mechanism in Seattle, ordered after the February 2026 grounding. After one of its pilots flagged a possible issue with the Dreamliner's fuel control switch, an Air India spokesperson on February 4 said the airline completed precautionary re-inspections of the Fuel Control Switch (FCS) across all operational Boeing 787 aircraft in its fleet and that no issues were identified during these checks. Meanwhile, the functioning of the fuel control switch in Dreamliners has been in focus in the wake of the fatal crash of Air India's Boeing 787-8 plane soon after take-off from Ahmedabad on June 12 last year.
A total of 260 people died in the crash of the aircraft that was bound for London Gatwick. In its preliminary report on the crash that was released on July 12 last year, the Aircraft Accident Investigation Bureau (AAIB) said the fuel supply to both engines of the plane was cut off within a gap of one second, causing confusion in the cockpit soon after take-off. "In the cockpit voice recording, one of the pilots is heard asking the other why did he cut off. The other pilot responded that he did not do so," it had said. Mohol, in the written reply on Monday (July 27), said there was no delay in the investigation. "The timeline for a major accident investigation cannot be predicted, as it depends on several factors and is an evolving process involving multiple variables.
