Air India Crash: Expert Analysis Dismisses TCMA Failure, Raises New Questions

Air India Crash: Expert Analysis Dismisses TCMA Failure, Raises New Questions
Challenging the Official Narrative
A recent video analysis by aviation expert Vikram V, known online as Wyngx, has cast doubt on the preliminary findings of the Aircraft Accident Investigation Bureau (AAIB) regarding the Air India AI-171 crash. Utilizing advanced 3D modeling and a meticulous frame-by-frame examination of publicly available footage, Vikram reconstructs the final moments of the Boeing 787, challenging both widely accepted theories and the official account of the incident.
With over a decade of experience in aviation safety and a reputation for detailed cinematic reconstructions, Vikram’s latest work not only disputes the AAIB’s initial conclusions but also raises broader concerns about pilot fatigue amid increasing travel demand and the sufficiency of existing safety protocols.
Key Issues Raised by the Simulation
Vikram’s analysis focuses on three critical points, notably dismissing the theory of a Thrust Control Malfunction (TCMA) and the possibility of an accidental fuel switch cut-off. The first question addresses how the aircraft continued to accelerate after the reported fuel cut-off. According to the AAIB’s preliminary report, the takeoff roll began at 1:37:37 pm, with the aircraft reaching V1 speed of 153 knots and peaking at 180 knots by 1:38:42 pm. The report states that immediately after reaching this speed, the engine fuel switches were moved to the cut-off position. However, Vikram’s simulation reveals that the aircraft continued to gain speed for an additional five seconds, reaching 196 knots—contradicting expectations that speed would stabilize or decline once the engines were shut down.
Secondly, the video questions whether the fuel switches were actually moved from the run to the cut-off position. While cockpit audio indicates that the pilots discussed the switches, there is no definitive evidence confirming that the action was taken. This ambiguity raises significant doubts about the sequence of events and the reliability of cockpit procedures under high-stress conditions.
Finally, the investigation has reignited debate over the role of cockpit video recordings in aviation safety inquiries. Industry experts argue that such recordings could provide crucial clarity in cases where audio and flight data logs fail to offer conclusive answers, potentially enhancing transparency and accuracy in accident analysis.
Broader Industry Implications and Ongoing Responses
The AI-171 crash has intensified scrutiny of pilot fatigue, particularly as airlines contend with rising passenger demand and increasingly compressed schedules. The incident has also triggered market concerns, including the prospect of higher insurance premiums and a renewed emphasis on safety standards across the industry. Competitors are reportedly reassessing their own safety protocols and pilot training programs in response to the tragedy.
Meanwhile, families of the victims have engaged a US law firm to explore legal avenues and advocate for a more comprehensive investigation. As the official inquiry proceeds, Vikram’s analysis highlights the urgent need for greater transparency and technological advancements in aviation safety. The questions raised by his simulation expose gaps in the current investigation and underscore the importance of robust data collection—including the potential use of cockpit video recordings—in preventing future disasters.

I have seen the Simulation video. The production is excellent, but it does not faithfully reproduce the tragic flight, as it yields different "data" from what is in the AAIB Preliminary Report. The latter must be taken as gospel until further information becomes available.
