Introduction

Airplane crashes are tragic events that often result in the loss of many lives. In order to prevent future accidents, investigations are carried out to determine the cause of these crashes. The black box, which consists of the flight data recorder (FDR) and the cockpit voice recorder (CVR), provides valuable information about the events leading up to the crash. This article will examine two airplane crashes, one in Roselawn, Indiana, and the other in Terrace, British Columbia, and the investigations that followed. The crashes occurred under different circumstances but shared common factors that contributed to the accidents. By understanding the causes of these crashes, we can learn valuable lessons to improve aviation safety.

The Crash in Roselawn, Indiana

On the evening of October 30, 1994, American Eagle Flight 4184 took off from Indianapolis with the intention of landing at Chicago's O'Hare International Airport. However, bad weather conditions and air traffic congestion caused the flight to be put in a holding pattern over rural Northeast Indiana. As the plane attempted to land, it encountered icing conditions, which led to a series of events that resulted in the crash. The plane descended rapidly and crashed into a soybean field, killing all 72 passengers and crew members on board.

Investigation by the NTSB

The National Transportation Safety Board (NTSB) was responsible for investigating the crash of Flight 4184. The lead investigator, Greg Fife, and his team were faced with the challenging task of determining what caused the accident. They meticulously examined the wreckage and gathered evidence to reconstruct the sequence of events. The investigation revealed that the crash was not caused by mechanical failure but rather by a combination of factors, including icing on the wings and a lapse in judgment by the pilots. The black boxes provided crucial insights into the actions and communications of the flight crew leading up to the crash.

The Crash in Terrace, British Columbia

In 1989, Skylink Airlines Flight 70 was en route from Vancouver to Terrace, British Columbia, when it encountered dense fog near the airport. The pilots aborted the landing but then lost control of the aircraft, which crashed into the forest. The impact resulted in a devastating fire, and all passengers and crew members were killed. The crash site presented numerous challenges to investigators, including the difficult terrain and the destruction caused by the fire. Despite these obstacles, investigators were determined to find the cause of the crash.

Analysis of the Crash Site

Forensic aviation experts from the Transportation Safety Board of Canada arrived at the crash site in Terrace to gather evidence and analyze the wreckage. They meticulously documented the location and condition of the wreckage, as well as the impact craters and patterns present in the terrain. The investigation revealed that the plane had crashed inverted, and the engine positions were switched on the ground. This led to the conclusion that the crash was the result of an in-flight breakup, rather than a mechanical failure or ground impact.

Reconstructing the Events of Flight 70

To understand what happened during the final moments of Flight 70, investigators relied on the data collected from the black boxes and the analysis of the cockpit voice recorder. The recordings provided insights into the pilots' actions and communications, as well as their level of concern about the situation. It was determined that the pilots became disoriented in the fog and mistakenly believed they were ascending when, in fact, they were descending. This confusion led to a rapid descent and ultimately the crash. The investigation also revealed human factors, such as the pilots' reliance on visual cues and their limited experience in flying in low-visibility conditions.

Role of Human Factors in the Accidents

In both the Roselawn and Terrace crashes, human factors played a significant role. The pilots' decision-making, situational awareness, and response to the challenges they faced were crucial factors in the outcome of the flights. The investigations highlighted the importance of proper training, adherence to procedures, and effective communication within the flight crew. The accidents served as reminders of the need for ongoing training and evaluation of pilots' skills to ensure safe operations.

Lessons Learned and Changes Made in Aviation

The investigations into the crashes of Flight 4184 and Flight 70 led to important changes in aviation practices and procedures. The NTSB and other regulatory bodies implemented recommendations to improve aviation safety. These included enhancements to de-icing systems, modifications to aircraft designs, and improvements in pilot training related to adverse weather conditions. The crashes served as catalysts for continuous improvement in aviation safety measures.

Conclusion

Airplane crashes are tragic events that demand thorough investigations to determine the causes and prevent future accidents. The crashes of Flight 4184 in Roselawn, Indiana, and Flight 70 in Terrace, British Columbia, revealed the complex interplay of factors that led to these accidents. Through the diligent work of aviation investigators, including the analysis of black box data and the examination of human factors, valuable lessons were learned and changes were made to enhance aviation safety. These efforts have contributed to the continuous improvement of aviation practices, ultimately making air travel safer for everyone involved.
