Indian aviation officials will travel to Boeing’s Seattle testing center as regulators intensify scrutiny of fuel-control switch systems tied to Air India’s Boeing 787 fleet.
Boeing’s Seattle-area testing operations have emerged as a focal point in an increasingly sensitive international aviation safety investigation involving Air India, Indian regulators, and the Boeing 787 Dreamliner fleet. Concerns over a fuel-control switch panel triggered renewed scrutiny of the aircraft manufacturer.
According to documents reviewed by Reuters, officials from India’s Directorate General of Civil Aviation, or DGCA, are expected to travel to Boeing facilities in the Seattle region in June. They will oversee testing of a fuel-control switch module removed from an Air India Boeing. 787. This follows an incident on a London-Bengaluru flight earlier this year.
The development places Boeing’s long-established Seattle manufacturing and engineering network at the center of a cross-border regulatory review that now involves Indian, British, and U.S. aviation stakeholders. Seattle has historically served as Boeing’s primary hub for commercial aircraft engineering and testing, including programs tied to the 787 Dreamliner, a wide-body aircraft extensively used on long-haul international routes by airlines including Air India.

The DGCA described the upcoming testing as “sensitive,” according to a March 9 email cited by Reuters, and instructed Air India to ensure the examination at Boeing’s original equipment manufacturer facility is conducted in the presence of Indian aviation officials.
The investigation stems from a February incident involving an Air India Boeing 787 operating between London and Bengaluru. During engine startup procedures in London, pilots reported that fuel-control switches did not remain fixed in the “run” position during the first two attempts when light pressure was applied, according to previous DGCA statements cited by Reuters. The switches reportedly stabilized during a third attempt, and the flight later continued to India without further operational issues.
The switch module was later removed and sent to Boeing’s Seattle facility for additional analysis, despite Boeing privately informing Air India that the component was considered “serviceable,” Reuters reported, citing emails and official correspondence.
Air India said in a statement that the module had been confirmed as “fully functional” by both Boeing and the DGCA, but added that further laboratory testing was being pursued “as a measure of abundant caution.” The airline said the additional examination would help “definitively confirm its performance and integrity” in a controlled environment. The Seattle testing comes amid broader international attention on Boeing 787 fuel-control switches following the June 2025 Air India crash in Gujarat that killed 260 people. Preliminary findings in that investigation indicated that fuel switches may have been moved nearly simultaneously, interrupting fuel supply to the aircraft’s engines.

The switches are designed to require deliberate pilot action before movement, making any questions involving their locking mechanisms particularly significant for investigators and regulators. Reuters reported that Indian officials now want Boeing engineers to examine whether pressure applied at certain angles could affect the locking system while the switch remains in the “run” position. The case has also attracted attention from British regulators because the February incident originated at London Heathrow Airport. Britain’s Civil Aviation Authority said it is monitoring Air India’s compliance with aviation safety procedures under existing oversight regulations.
For Indian American and South Asian aviation observers in the United States, the investigation underscores the increasingly interconnected nature of India-U.S. aerospace oversight. Boeing maintains deep commercial ties with India’s aviation market, where airlines including Air India have placed major aircraft orders as international travel demand grows rapidly.
Seattle’s role in the current inquiry also highlights how Boeing’s testing and engineering infrastructure remains central to global aircraft certification and post-incident analysis, particularly as regulators seek greater transparency following recent scrutiny of Boeing programs worldwide.
Reuters reported that Air India is expected to fund the DGCA officials’ visit to Seattle. The testing is scheduled to take place around the anniversary of the 2025 Gujarat crash, while India’s Aircraft Accident Investigation Bureau is expected to release a final report in the broader crash investigation next month.
