TransAsia Airways Flight 235 Crash: An Investigation

On February 4, 2015, TransAsia Airways Flight 235, a domestic flight from Taipei Songshan Airport to Kinmen Airport, crashed into the Keelung River shortly after takeoff. The tragic event resulted in the loss of 43 lives out of the 58 passengers and crew on board. The TransAsia Airways Flight 235 crash prompted an extensive investigation to determine the cause of the accident and prevent similar incidents in the future. This article delves into the details of the investigation, its findings, and the subsequent recommendations.

Initial Moments and the Crash

The flight took off from Taipei Songshan Airport at 10:52 AM local time. Just minutes after takeoff, the pilots reported an engine flameout in the number two engine. The turboprop ATR 72-600 aircraft began to lose altitude rapidly. In a desperate attempt to regain control, the pilots feathered the propeller of the malfunctioning engine. However, in a critical error, they also shut down the functioning number one engine. This action resulted in a complete loss of thrust, leaving the aircraft with no power.

The pilots struggled to restart the engines, but with insufficient altitude, they were unable to recover. The aircraft banked sharply to the left, clipping a taxiway bridge and then crashing into the Keelung River. The dramatic final moments were captured on dashcams and security cameras, providing crucial visual data for the investigation. The TransAsia Airways Flight 235 crash site became a scene of frantic rescue efforts, with emergency responders battling the cold river to recover survivors and bodies.

Investigation Team and Methodology

Following the crash, the Taiwan Transportation Safety Board (TTSB) launched a full-scale investigation. The team comprised experts in aviation safety, aircraft mechanics, flight operations, and human factors. International experts from France's Bureau d'EnquĂȘtes et d'Analyses pour la SĂ©curitĂ© de l'Aviation Civile (BEA) and the Transportation Safety Board of Canada (TSB) also joined the investigation, leveraging their expertise to ensure a comprehensive analysis. The investigation methodology included several key components:

  1. Data Collection: Gathering all available data, including the flight data recorder (FDR), the cockpit voice recorder (CVR), air traffic control recordings, witness statements, and maintenance records.
  2. Component Examination: Thorough inspection of the aircraft wreckage, engines, and other critical components to identify any mechanical failures or anomalies.
  3. Simulation and Modeling: Using flight simulators and computer models to recreate the flight path and evaluate different scenarios.
  4. Human Factors Analysis: Assessing the pilots' training, experience, decision-making processes, and overall performance.
  5. Regulatory Review: Examining the airline's operational procedures, safety management system, and regulatory oversight by the Civil Aeronautics Administration (CAA).

Key Findings of the Investigation

The investigation revealed a combination of factors that contributed to the TransAsia Airways Flight 235 crash. The key findings can be summarized as follows:

Engine Malfunction and Pilot Response

The initial engine flameout in the number two engine was attributed to a malfunction in the auto feather unit. However, the critical turning point was the pilots' decision to shut down the functioning number one engine. The CVR revealed that the pilots misidentified the malfunctioning engine and mistakenly shut down the good engine. This human error resulted in a complete loss of thrust, leaving the aircraft unable to maintain altitude.

Training and Proficiency

The investigation raised concerns about the pilots' training and proficiency, particularly in handling engine failures. The pilots' reaction to the engine flameout indicated a lack of proper understanding of the aircraft's systems and emergency procedures. The training programs at TransAsia Airways were found to be inadequate in preparing pilots for such scenarios. Simulator training did not adequately replicate the stress and complexity of real-world engine failures.

Crew Resource Management

The concept of Crew Resource Management (CRM), which emphasizes effective communication and decision-making within the cockpit, was also found to be lacking. The pilots did not effectively communicate with each other or follow standard operating procedures. The co-pilot, who was the pilot flying (PF), did not challenge the captain's decision to shut down the wrong engine, highlighting a breakdown in CRM principles.

Regulatory Oversight

The investigation also scrutinized the regulatory oversight provided by the CAA. The CAA's oversight of TransAsia Airways was found to be insufficient, with inadequate monitoring of the airline's training programs and safety management system. The CAA's audit processes did not effectively identify and address the deficiencies in the airline's operations.

Safety Recommendations

In response to the findings of the investigation, the TTSB issued a series of safety recommendations aimed at preventing similar accidents in the future. These recommendations targeted various stakeholders, including the airline, the regulator, and the aircraft manufacturer. The key safety recommendations included:

  • Enhanced Pilot Training: Improving pilot training programs to ensure that pilots are adequately prepared to handle engine failures and other emergencies. This includes more realistic simulator training and a greater emphasis on understanding aircraft systems.
  • Strengthened CRM: Reinforcing CRM principles to promote effective communication and decision-making within the cockpit. This involves training pilots to challenge errors and work together as a team.
  • Improved Regulatory Oversight: Enhancing the CAA's oversight of airlines to ensure compliance with safety regulations and identify potential risks. This includes more frequent and thorough audits of airlines' operations.
  • Aircraft Modifications: Evaluating potential modifications to the ATR 72-600 aircraft to improve its reliability and safety. This could include enhancements to the engine control system and the auto feather unit.
  • Public Awareness: Increasing public awareness of aviation safety issues to promote a culture of safety and encourage passengers to report any concerns.

Impact and Aftermath

The TransAsia Airways Flight 235 crash had a significant impact on the airline and the aviation industry in Taiwan. TransAsia Airways, which had been operating for over 60 years, faced severe financial difficulties in the aftermath of the accident. The airline's reputation was severely damaged, and passenger confidence plummeted. In November 2016, TransAsia Airways ceased operations, marking the end of an era.

The crash also led to increased scrutiny of aviation safety in Taiwan. The CAA implemented stricter regulations and increased oversight of airlines. The government invested in improving pilot training and upgrading aviation infrastructure. The accident served as a wake-up call, highlighting the importance of maintaining the highest standards of safety in the aviation industry.

Lessons Learned

The TransAsia Airways Flight 235 crash provides valuable lessons for the aviation industry worldwide. It underscores the importance of robust pilot training, effective crew resource management, and stringent regulatory oversight. The accident also highlights the potential consequences of human error and the need to design aircraft systems that are forgiving of mistakes. By learning from this tragedy, the aviation industry can work to prevent similar accidents and ensure the safety of air travel.

Conclusion

The TransAsia Airways Flight 235 crash was a tragic event that claimed the lives of 43 people. The investigation revealed a complex combination of factors, including engine malfunction, human error, inadequate training, and insufficient regulatory oversight. The safety recommendations issued in response to the accident aim to prevent similar incidents in the future. The crash serves as a stark reminder of the importance of maintaining the highest standards of safety in the aviation industry and continuously striving for improvement. Guys, always remember that aviation safety is not just a set of rules, but a culture that needs to be fostered and upheld by everyone involved. Stay safe up there!
