Indian Airlines Flight 605, a domestic scheduled passenger flight operating from Bombay (now Mumbai) to Bangalore, tragically crashed on 14 February 1990. This devastating incident, which occurred during its final approach to Bangalore's HAL Airport, resulted in the loss of 92 lives, including 4 crew members and 88 passengers. The crash of Flight 605 remains a significant event in Indian aviation history, prompting investigations and safety reviews to prevent similar occurrences. This analysis delves into the details surrounding the crash, exploring the sequence of events, potential causes, and the aftermath of this tragic event.

Background of Indian Airlines Flight 605

Indian Airlines Flight 605 was a regularly scheduled domestic passenger flight, connecting the bustling metropolis of Bombay (now Mumbai) with the vibrant city of Bangalore. The flight was operated using an Airbus A320-200, a technologically advanced aircraft known for its fly-by-wire control system. On the fateful day of February 14, 1990, the aircraft, carrying 146 people, including crew members, commenced its journey from Bombay's Sahar International Airport. The flight proceeded uneventfully until its approach to Bangalore's HAL Airport. Understanding the context of this flight, including its origin, destination, and the type of aircraft used, is crucial to comprehending the events that unfolded during its final moments. The Airbus A320-200 was relatively new to the Indian Airlines fleet at the time, and its advanced technology played a significant role in the subsequent investigation and analysis of the crash. The crew's familiarity with the aircraft and its systems became a focal point in understanding the human factors that might have contributed to the accident. The flight's scheduled route was a common one, frequented by business travelers, tourists, and residents connecting between the two major Indian cities. This routine nature of the flight underscores the unexpected and shocking nature of the tragedy that occurred. As the flight approached Bangalore, weather conditions and visibility became important factors, adding complexity to the already challenging task of landing. The combination of advanced technology, human factors, and environmental conditions ultimately converged to create the circumstances that led to the devastating crash.

Sequence of Events Leading to the Crash

The sequence of events leading to the crash of Indian Airlines Flight 605 is critical to understanding the factors that contributed to this tragedy. As the aircraft approached Bangalore's HAL Airport, it encountered clear weather conditions, but the pilots faced challenges during the final descent. The Airbus A320 was equipped with a fly-by-wire system, which controlled the aircraft's movements electronically. During the approach, the pilots configured the aircraft for landing, but the descent rate was higher than recommended. Despite warnings from the Ground Proximity Warning System (GPWS), the pilots continued the descent. The aircraft touched down hard, bounced, and the pilots initiated a go-around. However, the engines did not respond immediately, and the aircraft failed to gain sufficient altitude. It crashed into a golf course short of the runway. The flight data recorder (FDR) and cockpit voice recorder (CVR) provided vital information about the pilots' actions and the aircraft's performance in the moments leading up to the crash. The FDR revealed that the aircraft's descent rate was excessive, while the CVR captured the pilots' communication and their response to the warnings. The delay in engine response during the attempted go-around was a crucial factor in the crash. The investigation focused on whether this delay was due to a technical malfunction or pilot error. The sequence of events highlights a combination of factors, including the high descent rate, delayed engine response, and the pilots' decision-making process. Understanding this sequence is essential to identifying the root causes of the crash and implementing measures to prevent similar accidents in the future. The communication between the pilots and air traffic control, the aircraft's configuration during the approach, and the performance of the fly-by-wire system all played a role in the unfolding events. By analyzing each step in the sequence, investigators were able to piece together a comprehensive picture of the circumstances that led to the tragic outcome.

Probable Causes of the Crash

The probable causes of the crash of Indian Airlines Flight 605 were multifaceted, stemming from a combination of pilot error, technical factors, and environmental conditions. The primary cause was attributed to the pilots' failure to maintain a safe descent rate during the final approach, leading to a hard landing and subsequent failed go-around. The delay in engine response during the attempted go-around was also a significant contributing factor. Investigators examined the aircraft's systems and the pilots' actions to determine why the engines did not respond immediately when the pilots attempted to increase thrust. The fly-by-wire system of the Airbus A320, while advanced, also came under scrutiny. The investigation explored whether the pilots fully understood and effectively managed the aircraft's automated systems. Environmental conditions, such as wind shear or turbulence, were considered, but the weather was generally clear, suggesting that these factors played a minimal role. Human factors, including pilot fatigue, training, and communication, were also examined. The investigation sought to understand whether the pilots were adequately trained to handle the challenges of landing the Airbus A320 and whether communication between the pilots was effective. The analysis of the cockpit voice recorder (CVR) provided insights into the pilots' decision-making process and their interaction with each other. Ultimately, the crash was attributed to a chain of events, with no single cause. The combination of pilot error, technical factors, and the complexity of the aircraft's systems created a situation where the pilots were unable to recover from the initial hard landing. The investigation emphasized the importance of continuous training, adherence to standard operating procedures, and a thorough understanding of aircraft systems to prevent similar accidents in the future. By identifying the probable causes, aviation authorities were able to implement safety recommendations and improve pilot training programs.

Aftermath and Impact

The aftermath of the Indian Airlines Flight 605 crash was profound, leaving a lasting impact on the aviation industry, the families of the victims, and the public. The crash triggered a thorough investigation by aviation authorities to determine the causes and contributing factors. The findings led to several safety recommendations aimed at improving pilot training, aircraft maintenance, and air traffic control procedures. The incident also prompted a review of the Airbus A320's fly-by-wire system and its operational protocols. One of the most significant impacts was the increased emphasis on Crew Resource Management (CRM) training for pilots. CRM training focuses on improving communication, decision-making, and teamwork in the cockpit, with the goal of preventing human errors that can lead to accidents. The families of the victims faced immense grief and sought justice and compensation. The legal proceedings and settlements that followed the crash highlighted the importance of airline accountability and passenger rights. The crash also had a psychological impact on the aviation community, with pilots and air traffic controllers experiencing increased stress and anxiety. The incident served as a stark reminder of the potential consequences of errors and the need for vigilance in all aspects of aviation. In the aftermath, Indian Airlines implemented several measures to enhance safety, including upgrades to its training programs and stricter adherence to standard operating procedures.
