The association criticized the preliminary report for what it described as unfair insinuations against the flight crew. Concurrently, certain Western media outlets have speculated about possible confusion in the cockpit, implying pilot error as a contributing factor. The Aircraft Accident Investigation Bureau (AAIB), in its initial findings, appeared to suggest this possibility but refrained from making explicit accusations. Notably, the AAIB’s report included only two paraphrased sentences from the pilots’ cockpit exchange, omitting the full audio transcript and raising significant concerns about transparency. Unresolved Operational Details and Safety Concerns Critical details surrounding the incident remain unclear. First officer Clive Kunder, aged 32, was at the controls during the event, with the pilot-in-command, Sumeet Sabharwal, 56, overseeing operations. It has not been established which pilot questioned the other regarding the shutdown of the fuel switches. The first fuel switch was turned off at 1:38:42 pm, but the crew took approximately ten seconds to reactivate it—a delay that has attracted scrutiny. Furthermore, the fuel supply to the second engine was restored four seconds after the first, rather than simultaneously. While the first engine responded promptly, the second continued to experience difficulties. These operational uncertainties are compounded by prior concerns raised by the US Federal Aviation Administration (FAA), which had flagged potential issues with Boeing’s fuel switch locking mechanism as early as 2018. The maintenance history of the fuel switches on this specific aircraft remains undisclosed. Calls for Transparency Amid Ongoing Investigation There is a growing demand for the AAIB to release the full transcript of the cockpit audio. Advocates argue that only complete transparency can dispel suspicions that the preliminary report was crafted to assign blame to the pilots, who tragically cannot defend themselves. Full disclosure is also seen as essential to provide some measure of closure to the victims’ families, even as the final investigation report may take up to a year to be completed. However, the release of the full transcript presents challenges. The investigation remains active, and legal considerations may restrict the immediate publication of sensitive audio recordings. Beyond legalities, the aviation industry is closely monitoring Air India’s response, with heightened scrutiny on its operational protocols and safety standards. Rival airlines are reportedly reviewing their own safety procedures and may increase pressure on Air India to demonstrate full transparency. At present, no definitive conclusions have been drawn regarding the cause of the crash. The insistence on releasing the full cockpit transcript highlights the broader imperative for openness and accountability, both to ensure a fair investigation and to restore public confidence in aviation safety.
