The Indian government informed parliament that the inspection conducted by Boeing at the request of the DGCA regarding the fuel control switch locking mechanism on the B787 Dreamliner aircraft found no deviations.
Reasons for the Inspection
The regulator initiated a re-examination after the crew operating AI Dreamliner (VT-ANX) on a flight from London to Bengaluru in February discovered an issue with the switch after a safe landing and reported it.
Context of Incident Investigations
These switches, which are responsible for supplying fuel to the engines, are under close scrutiny following the AI 171 crash last June, which occurred just seconds after takeoff from Ahmedabad due to engine fuel exhaustion. Although the cause of this incident is still being determined, the fuel control switch locking system has undergone multiple checks to ensure the safety of other Dreamliners operating worldwide. These investigations are ongoing by the Aircraft Accident Investigation Bureau (AAIB).
Results of Technical Examination
Minister of State for Aviation, Murliadhar Mohol, stated in a parliamentary response on Wednesday that as part of continuous airworthiness, the DGCA instructed the Original Equipment Manufacturer (OEM) to test the fuel control switch locking mechanism in Seattle. A detailed check of the fuel control switch, including the structural integrity of its fasteners, was conducted, and no violations were found.
Next Steps and Previous Incidents
However, the minister specified that an additional inspection of the full thrust control module is currently underway at the OEM's facility. This module converts pilot or autothrottle commands into precise electronic signals for engine power control. On February 2, 2026, the AI Dreamliner aircraft, about which the crew reported the fuel control switch issue after landing in Bengaluru, was taken for maintenance. At that time, AI stated that it was aware of a possible fuel control switch defect on the Boeing 787-8 aircraft and grounded the plane upon receiving this information, engaging the OEM for an urgent review of the pilot's concerns. This situation was brought to the attention of the aviation regulator, the DGCA. Following the DGCA's directive, the airline Air India checked the fuel control switches on all its Boeing 787 aircraft and found no problems.
Information on AI 171 Crash
The preliminary AAIB report on the AI 171 crash contained a cockpit voice recorder recording where one pilot is heard asking another why he disengaged (the fuel control switch). The second pilot replied that he did not do so. Mohol also noted on Wednesday that there are no delays in the investigation of the AI 171 incident. He emphasized that the timeline for a major investigation depends on many factors and is an evolving process, and the final report will be published on the AAIB website upon completion.
