In the video "WHY DID THE VOEPASS PLANE CRASH? Lito Sousa from Aviões e Músicas Explains Possibilities," available on YouTube, Lito Sousa provides a detailed analysis of the Voepass plane crash, offering valuable insights into the factors that might have contributed to the incident. Let’s explore the key points discussed by Sousa and understand the possible causes of the crash.
The ATR 42/72 and Its Features
The ATR 42/72 is a turbo-propeller aircraft model widely used for regional aviation operations. Designed for short-distance flights, the ATR is efficient on small and unpaved runways, making it a popular option for airlines around the world. These planes have low operating costs and are known for their ability to operate under varied conditions.
Issues Related to Ice
One of the points discussed in the video is the formation of ice on the ATR 42/72's wings. Ice formation can be a significant issue, especially because these aircraft fly at altitudes where ice tends to form. Ice can affect the aerodynamics of the wings, causing disruption in the airflow and potentially leading to a loss of control.
Sousa highlights that although ice protection systems have been improved over the years, the pilot still needs to take additional measures, such as descending to a lower altitude to increase air temperature and remove ice from the wings. If ice forms on critical areas like the control actuators, it can lead to a loss of maneuverability, which could be a hypothesis for the crash.
Investigation and Contributing Factors
It’s important to note that ice is just one of many factors that can contribute to a crash. Sousa emphasizes that a single factor rarely causes an accident; it is usually a combination of various circumstances. The investigation is crucial to identify the chain of events leading to the crash. In the case of the Voepass ATR, it is still early to assert if ice formation was the direct cause of the incident.
Sousa also mentions that despite some previous accidents involving the ATR being caused by ice formation, this should not lead to a hasty conclusion that the model is inherently unsafe. The ATR is certified and safe to operate when following proper procedures. Voepass, being the oldest Brazilian airline with a fleet of ATRs, had never previously recorded such an accident.
The Need for Detailed Analysis
To fully understand the causes of the crash, it is necessary to examine the official investigation, including the flight data recorders. Only with this information can it be determined if there were mechanical failures or human errors. The crash of Air France 447 is an example of how investigations can take years to reveal the truth, highlighting the complexity of events that can lead to an aviation accident.
In summary, Lito Sousa’s analysis suggests that while ice formation could have been a contributing factor, many other aspects need to be considered to understand the exact cause of the crash. The ongoing investigation will be crucial in clarifying the details and preventing similar incidents in the future.
