The Air India Flight AI 171 crash in Ahmedabad, India, has prompted a comprehensive investigation into its causes, with a preliminary report expected to provide initial insights into the tragic event. The crash, which occurred just 30 seconds after takeoff, resulted in the deaths of all but one of the 242 individuals on board, as well as over 30 people on the ground when the Boeing 787 Dreamliner plummeted into a hostel for medical students. The investigation, led by India's Aircraft Accident Investigation Bureau (AAIB), aims to unravel the complex circumstances leading to the catastrophic failure, focusing on potential engine malfunctions, fuel system anomalies, and pilot actions. While authorities have been cautious in releasing specific details, the preliminary report is anticipated to shed light on the sequence of events that culminated in the crash, offering a factual account of the crucial moments preceding the disaster. The report is unlikely to assign blame or draw definitive conclusions, as investigators continue to meticulously analyze the available evidence to construct a comprehensive understanding of the accident. The loss of altitude and subsequent impact suggest a critical system failure or a confluence of factors that overwhelmed the flight crew's ability to maintain control of the aircraft. Bjorn Fehrm, an aerospace analyst and former fighter pilot, noted the unusual nature of the power loss, emphasizing the simultaneous failure of both engines without any apparent external causes like bird strikes. This observation raises serious questions about the integrity of the engine control systems or the potential for a common mode failure affecting both power plants. The fact that the 787 Dreamliner is designed to complete a takeoff on a single engine further underscores the gravity of the dual engine failure scenario, as pilots are trained to handle such emergencies effectively. The focus of the investigation has honed in on the fuel control switches located in the center console of the cockpit, which regulate fuel supply to the GE Aerospace engines. The possibility of these switches being toggled, either inadvertently or intentionally, is being carefully examined, as the interruption of fuel flow to both engines could have triggered the catastrophic loss of power. The Wall Street Journal reported preliminary findings suggesting that the fuel switches were indeed turned off, although the circumstances surrounding this action remain unclear. Whether the switches were accidentally manipulated or intentionally shut off, and whether any attempts were made to restore fuel flow, are critical questions that investigators are striving to answer. The retrieval of the cockpit voice recorder (CVR) and flight data recorder (FDR) from the wreckage has provided invaluable data for the investigation. The analysis of these recordings will help reconstruct the events in the cockpit and monitor critical flight parameters, providing insights into the pilots' actions, system responses, and the overall condition of the aircraft during the final moments of the flight. The investigation is also considering the backgrounds and experience of the pilots, Captain Sumeet Sabharwal and First Officer Clive Kunder, who had 8,200 and 1,100 flight hours, respectively. Understanding their training, proficiency, and familiarity with the 787 Dreamliner's systems could shed light on their decision-making process during the emergency. The deployment of the ram air turbine (RAT), an emergency backup power source, suggests that the aircraft experienced a significant loss of power, prompting the automatic or manual activation of the RAT to provide essential electrical and hydraulic power. However, at the low altitude and speed at which the 787 found itself after takeoff, restarting the engines may have been impossible, leaving the flight crew with limited options to avert the crash. John Cox, a former airline pilot and CEO of Safety Operating Systems, emphasized the immediate impact of cutting off fuel supply to the engines, stating that they would stop running in seconds. He also highlighted the possibility of pilot error, such as mistakenly cutting off fuel to the functioning engine instead of the failed one, as well as the potential for a deliberate act. The article also brings to light previous incidents where pilots have mistakenly cut off fuel to engines, emphasizing that the circumstances and available altitude played a crucial role in whether or not a catastrophe occurred. The possibility of the pilots following an emergency checklist for dual engine failure, which instructs them to cycle the fuel switches to cutoff and then back to run, is also being considered, as this procedure allows the electronic engine control system to reset. The investigation into the Air India crash is a complex undertaking that requires the meticulous examination of all available evidence, including flight data, cockpit recordings, witness statements, and aircraft maintenance records. By carefully piecing together the events leading to the accident, investigators hope to identify the root causes and contributing factors, enabling them to develop recommendations to prevent similar tragedies from occurring in the future.
