Until recently, the Boeing 787 Dreamliner had one of the cleanest safety records in aviation history. However, on June 12, 2025, the first fatal crash involving the type occurred when Air India Flight 171, a Boeing 787-8, crashed shortly after takeoff from Ahmedabad, India. The aircraft struck a hostel block at B. J. Medical College, resulting in the loss of 242 lives (230 passengers and 12 crew) and 19 additional fatalities on the ground. This was the first "hull loss" and fatal accident for the Dreamliner since it entered service in 2011. Preliminary investigations and a 2026 whistleblower report have focused on a potential "chain of events" involving unintentional activation of fuel control switches in the cockpit, combined with historical reports of electrical malfunctions on that specific airframe. Prior to this tragedy, the Dreamliner's only major safety crisis was the 2013 fleet-wide grounding due to lithium-ion battery fires, but those incidents did not result in any crashes or loss of life, leaving the 2025 Ahmedabad disaster as the sole fatal event in the aircraft's history.
