Ongoing Investigation Delves into Ambiguities Behind Air India Flight 171 Crash

In an alarming twist to the investigation of the Air India Flight 171 crash which resulted in 260 fatalities, preliminary findings reveal significant oddities based on cockpit recordings. Just seconds following the takeoff, the 12-year-old Boeing 787 Dreamliner's fuel-control switches were unexpectedly shifted to the "cut-off" position, disabling fuel flow to the engines and causing an immediate loss of power. This maneuver is typically reserved for post-landing procedures.The cockpit voice recording has one pilot inquiring about the action of shutting off the fuel supply, to which the other pilot responds he did not perform that action. This crucial exchange does not clarify the identity of either pilot at the time. During the incident, the co-pilot was in control of the aircraft, while the captain was monitoring.The aircraft had barely ascended 625 feet before it lost data visibility 50 seconds into the flight, resulting in a crash within a densely populated area of Ahmedabad, India, and raising urgent questions about the flight's circumstances. A new 15-page report reveals initial insights from investigations being conducted by Indian authorities, alongside teams from Boeing, General Electric, Air India, and regulatory bodies from the US and UK.The investigation highlights that the locking mechanism for the fuel-switch levers is designed to prevent accidental activation—requiring a two-step process to move them. An aviation investigator from Canada remarked on the unusual nature of this incident, given the historical reliability of such safety features. As experts analyze the recordings, they assert that it is paramount to ascertain who actuated the switches and for what reason. The conversations captured in the cockpit voice recorder seem insufficient to conclude whether the switches were intentionally or mistakenly engaged. This mysterious twist of events raises concerns about potential lapses in judgment or actual technical malfunctions.Understanding the sequence of events following the engine shutdowns may also prompt discussion on the need for cockpit video recorders, as suggested by the National Transportation Safety Board (NTSB). Currently, both pilots had their performance validated prior to the flight, showing no apparent signs of impairment.Adding complexity to the investigation is a historical advisory issued in December 2018 by the US Federal Aviation Administration regarding possible issues with the fuel control switches in certain Boeing models, paralleling the switch design in the 787 series. While it was deemed unworthy for a mandatory corrective measure, it has raised questions about the robustness of the aircraft’s components.Concerns linger over whether the switches might have malfunctioned due to an electronic control issue within the aircraft, a hypothesis that has not been dismissed by industry experts. The investigation remains wide-ranging, with various aviation professionals weighing in on technical aspects alongside the critical insights to be gleaned from cockpit audio review.The report from a recent analysis cited the deployment of the Ram Air Turbine (RAT), indicating significant operational failure and revealing that essential systems were compromised. The inability of the pilots to retract landing gear and manage the engine failure further emphasizes the catastrophic nature of the scenario they encountered.While the investigation continues, calls for clearer regulations and improvements in cockpit monitoring technology come to the forefront as the aviation community grapples with unexpected tragedies. The tragic loss of life, and the potential lessons learned from these circumstances, underscores the urgent need for enhanced safety protocols in aviation.
