New Delhi, Oct. 17 -- The father of late Capt. Sumeet Sabharwal, who commanded the Air India Boeing 787 Dreamliner that crashed shortly after take-off from Ahmedabad on June 12, has moved the Supreme Court along with the Federation of Indian Pilots (FIP), seeking a judicially monitored investigation into the accident. He has also sought closure of the ongoing probe by the Aircraft Accident Investigation Bureau (AAIB). The writ petition, filed on October 10 under Article 32 of the Constitution, requests that a committee headed by a retired Supreme Court judge and comprising independent aviation experts be constituted to conduct a fair and transparent inquiry into the crash. It claims the preliminary report prepared by the Aircraft Accident Investigation Bureau (AAIB) is "defective, biased, and incomplete",because it attributes the cause of the accident to pilot error while disregarding serious technical and systemic factors that merit independent scrutiny. On June 12, Air India's Boeing 787-8 aircraft en route to London Gatwick from Ahmedabad crashed into a building soon after take-off, killing 260 people. A preliminary probe by AAIB into the crash revealed that both engines were inadvertently shut off during the initial climb, leading to a catastrophic loss of thrust and subsequent crash. According to the AAIB report, the initial data of the aircraft indicated the aircraft achieved normal takeoff parameters. However, within seconds of becoming airborne, the fuel control switches for both engines transitioned from "RUN" to "CUTOFF", halting fuel supply and shutting down the engines. It also, in a line, mentioned that one pilot asked the other why he had done so, to which the other denied. Capt Sabharwal's father Pushkar Raj Sabharwal and FIP, which counts around 6,000 pilots as its members, have sought that the current probe be set aside and all records be transferred to a judicially monitored committee. Their plea argues that only an independent, expert-led investigation can ensure accountability, restore public confidence, and prevent recurrence of such tragedies. The plea states that Capt. Sabharwal, who had over 30 years of incident-free flying and over 15,000 flight hours, was among the most experienced commanders on the Boeing 787 fleet; that the ongoing probe has been prejudiced against the deceased pilot, who is unable to defend himself; and that a one-sided inquiry not only tarnishes his reputation but also poses a threat to public safety by failing to identify the true cause of the crash. The plea points to several inconsistencies in the preliminary report. The aircraft's Ram Air Turbine (RAT), an emergency power generator which deploy automatically when both primary and backup electrical systems fail, was activated before the pilots could make any control inputs, it says. This, it claims, indicates an electrical or software malfunction rather than any human error. The plea also said the simultaneous failure of the Emergency Locator Transmitter (ELT), which didn't activate after impact, highlighting it as further evidence of a complete electrical collapse. The composition of the five-member AAIB probe team violates the principle of natural justice since it includes officials from the Directorate General of Civil Aviation (DGCA), whose regulatory oversight is itself under examination, the plea said. The inclusion of representatives from Boeing and GE, whose equipment was involved compromised the probes independence, the petition adds....
