Investigating the Causes: What Went Wrong?

Following the Kathmandu air crash 2022, a detailed investigation was launched to determine the exact cause of the accident. Several factors were considered, including mechanical failure, pilot error, and environmental conditions. Let's break down some of the key areas of investigation:

• Mechanical Failure: Investigators meticulously examined the wreckage of the ATR 72-500 for any signs of pre-impact mechanical issues. This included analyzing the engines, control surfaces, and hydraulic systems. Initial findings suggested that both engines were producing power upon impact, ruling out a complete engine failure. However, further analysis was needed to determine if there were any anomalies in engine performance or control systems that could have contributed to the crash. The investigation also looked into the maintenance history of the aircraft. Records were reviewed to ensure that all scheduled maintenance checks were performed correctly and that there were no outstanding issues that could have affected the aircraft's airworthiness. Any previous incidents or reported problems with the aircraft were also scrutinized. Furthermore, the investigators considered the age of the aircraft and the possibility of component fatigue. While the ATR 72-500 is a reliable aircraft, older models may be more susceptible to wear and tear, which could increase the risk of mechanical failure. The investigators worked closely with the aircraft manufacturer, ATR, to gain a deeper understanding of the aircraft's systems and potential failure modes. ATR provided technical expertise and support to the investigation team. Advanced diagnostic techniques were used to analyze the recovered components. This included metallurgical analysis to detect any signs of stress, corrosion, or other material defects.
• Pilot Error: Human factors played a significant role in the investigation. The pilots' experience, training, and decision-making processes were all closely examined. Investigators reviewed the pilots' flight records, training history, and medical reports to assess their qualifications and fitness to fly. Cockpit voice recordings (CVR) were analyzed to understand the communication between the pilots and air traffic control during the final moments of the flight. This provided insights into the pilots' actions, decisions, and any potential communication breakdowns. The investigation also considered the pilots' workload and fatigue levels. Long hours and demanding flight schedules can impair pilot performance and increase the risk of errors. The investigators looked into the airline's crew scheduling practices and whether they complied with safety regulations. Furthermore, the investigation explored the pilots' familiarity with the Pokhara airport and its approach procedures. The new airport had only been operational for a short time, and it was crucial to determine if the pilots were adequately trained and prepared for the unique challenges of landing there. The investigation also considered the possibility of spatial disorientation, a phenomenon in which pilots lose their sense of orientation and altitude. This can be particularly dangerous during approach and landing. The investigators used flight data recorder (FDR) information to reconstruct the flight path and analyze the pilots' control inputs.
• Environmental Conditions: While initial reports indicated clear weather, investigators still examined weather conditions and other environmental factors that may have contributed to the crash. Although the weather was not considered a primary cause, investigators checked for any localized weather phenomena, such as wind shear or turbulence, that may have affected the aircraft's stability during the approach. They analyzed weather data from various sources, including weather stations, pilot reports, and satellite imagery. The investigation also considered the terrain surrounding the Pokhara airport. The airport is located in a valley, which can create challenging wind conditions and increase the risk of accidents. The investigators assessed the potential impact of the terrain on the aircraft's flight path and stability. Furthermore, the investigation explored the possibility of bird strikes. Bird strikes can cause significant damage to aircraft engines and other critical systems. The investigators examined the wreckage for any evidence of bird strikes and reviewed reports of bird activity near the airport.
