Air India Crash Investigation Misses One-Year Deadline as Engine Analysis Remains Incomplete

The Quick Take

• India's Air India crash investigation will miss its one-year anniversary deadline as engine examination remains incomplete.
• Preliminary findings already revealed that both engine fuel control switches moved to 'CUTOFF' shortly after takeoff.
• The investigation delay creates continued regulatory uncertainty for Air India's fleet operations and Tata Sons' aviation strategy.

NDTV Profit reports that investigators probing the Air India crash will miss the one-year anniversary deadline for completing their final report, citing incomplete examination of the aircraft's engines as the primary reason. A preliminary report released earlier identified a critical anomaly: both of the Boeing 787's engine fuel control switches moved almost simultaneously from 'RUN' to 'CUTOFF' shortly after takeoff, starving both engines of fuel. This finding — if confirmed in the final report — points to a catastrophic double-switch event of extraordinary rarity, and the forensic analysis of the engine hardware is essential to determining whether the switches moved due to mechanical failure, human error, or a systemic aircraft defect.

The investigation delay has direct financial implications for several parties. For Air India, parent Tata Sons faces continued reputational overhang and regulatory uncertainty around fleet operations until the final investigation report is published. For Boeing, the preliminary finding of a potential double-switch failure on a 787 Dreamliner is a serious liability exposure, particularly given Boeing's concurrent challenges with its 737 MAX program and FAA oversight intensification. Aviation insurance underwriters face prolonged uncertainty about the ultimate liability allocation between the airline, the aircraft manufacturer, and potentially the switch-component supplier.

Key signals to watch include the AAIB interim report expected before the final annual report, any Boeing safety bulletin related to the fuel control switch design, and Directorate General of Civil Aviation orders affecting Air India's 787 fleet operations. The macro variable for Air India and Tata Sons' aviation ambitions is the final investigative determination of root cause — a pilot-error finding would limit Tata's regulatory exposure, while a systemic aircraft defect finding would expose Boeing to global liability and trigger DGCA airworthiness directives affecting India's fleet.
