Compounding Factors The black box data aligns with other evidence. Kundar’s biometric data showed his heart rate spiking to 160 bpm at 13:38:20, indicating acute stress that likely impaired his reaction time. The CVR, previously reported, captured Kundar questioning throttle settings at 13:37 IST, suggesting he noticed an anomaly, possibly due to the seat’s alignment affecting lever positioning. Emergency crew footage showed a fatal pitch-up at 13:38:40, increasing the angle of attack to 18 degrees, beyond the 787’s stall threshold of 12–14 degrees. This maneuver, likely Sabharwal’s attempt to regain altitude, exacerbated the stall. Thermal imaging from the right engine, taken 48 hours prior, revealed overheating spots (650°C) in the turbine, dismissed as “normal.” FDR data confirmed the right engine’s exhaust gas temperature was 15% higher than the left, reducing thrust efficiency. The maintenance log revealed the seat issue was reported on March 15 and May 31, 2025, but marked ...
