The incident prompted a thorough investigation to determine the cause of the crash and to prevent similar accidents in the future. The details of the crash, including the low approach and the impact with the ground, pointed to potential issues with pilot error, aircraft systems, or a combination of both. The investigation would delve into these factors to provide a comprehensive understanding of what went wrong on that fateful day.

The Investigation

Following the Indian Airlines Flight 605 crash, a comprehensive investigation was launched to determine the cause of the accident. The investigation team comprised experts from various fields, including aviation safety, engineering, and human factors. Their primary goal was to piece together the events leading up to the crash and identify any factors that could have contributed to the disaster. One of the first steps in the investigation was to recover and analyze the aircraft's black boxes, which included the Cockpit Voice Recorder (CVR) and the Flight Data Recorder (FDR). These devices provided crucial information about the pilots' actions and the aircraft's performance in the final moments of the flight. The CVR captured the conversations between the pilots and air traffic control, while the FDR recorded data such as altitude, speed, and engine performance. Analyzing this data, the investigators discovered that the aircraft was flying too low during its approach, as corroborated by eyewitness accounts. They also found that the pilots had received warnings from the aircraft's Ground Proximity Warning System (GPWS), which alerts the crew when the plane is dangerously close to the ground. Despite these warnings, the pilots did not take corrective action in time to prevent the crash. The investigation also examined the role of the Airbus A320's fly-by-wire system. This advanced technology was designed to enhance safety and simplify flight control, but it also introduced a layer of complexity that required thorough training and understanding. The investigators looked into whether the pilots were adequately trained to handle the fly-by-wire system and whether any malfunctions in the system could have contributed to the crash. In addition to technical factors, the investigation also considered human factors, such as pilot fatigue, stress, and communication. They analyzed the pilots' backgrounds, training records, and medical histories to identify any potential issues that could have affected their performance. The investigation was a meticulous and thorough process, aimed at uncovering all possible causes of the crash and preventing similar incidents in the future.

Findings and Causes

The investigation into the Indian Airlines Flight 605 crash ultimately pointed to a combination of factors that led to the tragic accident. The primary cause was attributed to pilot error during the final approach. The pilots failed to maintain the correct glide path, allowing the aircraft to descend too low and too rapidly. This deviation from the standard approach procedure was a critical mistake that set in motion a chain of events leading to the crash. Despite receiving warnings from the Ground Proximity Warning System (GPWS), the pilots did not respond effectively to correct the situation. The GPWS is designed to alert the crew when the aircraft is dangerously close to the ground, providing them with an opportunity to take evasive action. However, in this case, the pilots' response was either delayed or insufficient, resulting in the aircraft impacting the ground short of the runway. The investigation also considered the role of the Airbus A320's fly-by-wire system. While the system itself was not found to be faulty, the investigators noted that the pilots' understanding and management of the system may have been a contributing factor. The fly-by-wire system is complex, and it requires pilots to be thoroughly trained and proficient in its operation. Any confusion or mishandling of the system could potentially lead to errors in flight control. In addition to pilot error and the fly-by-wire system, the investigation also examined other potential factors, such as weather conditions, air traffic control procedures, and maintenance records. However, these factors were not found to be significant contributors to the crash. The final report concluded that the primary cause of the accident was the pilots' failure to adhere to standard operating procedures and their inadequate response to the GPWS warnings. This tragic event highlighted the importance of pilot training, adherence to safety protocols, and effective communication in preventing aviation accidents.
