Brasilia/Prensa Latina
Brazil’s Center for Investigation and Prevention of Aeronautical Accidents (Cenipa) reported on Sunday that it managed to extract and recover the contents of the two black boxes removed from the plane that crashed in the state of Sao Paulo. “The data was obtained, validated, and now we await the line of investigation from our investigators, who are still here with me (in Sao Paulo),” revealed Brigadier Marcelo Moreno, head of Cenipa.
He said they will return to Brasilia to work on transforming this huge number of statistics into useful information for society.
The plane crash occurred last Friday and caused the death of 62 people (58 passengers and four crew members). Now, in this capital, experts will be in charge of analyzing the contents of the black boxes.
According to Moreno, the aircraft’s two engines will be analyzed in Sao Paulo to verify whether they were working at the time of the accident.
He said the preliminary investigation report will be presented within 30 days.
Three representatives of France’s Bureau of Investigation and Analysis for Civil Aviation Safety (BEA) arrived at the scene of the tragedy on Sunday.
The BEA was activated by the Brazilian authorities and must collaborate in the investigations since the aircraft that crashed, model ATR-72, was manufactured in France.
Moreno is also waiting in the town of Vinhedo, in the state of Paraná, where the plane departed, for representatives of the Transportation Safety Board of Canada (TSB), the country where the engines were manufactured.
The BEA and the TSB are similar to Cenipa. Experts from the three countries must act jointly in the investigation that must identify the causes of the accident.
Obtaining data from the two flight recorders, popularly known as black boxes, is essential for the investigation. One of the devices records audio and the other accumulates data such as altitude and speed during the flight.
With aircraft data and cockpit audio, experts can understand the dynamics and factors that may have contributed to the aircraft’s crash.
Mandatory on most aircraft, black boxes were invented in 1950 by Australian David Warren. They record data in order to identify the causes of accidents and thus help prevent them.
The boxes are not actually black, they are painted orange, a colour that can be seen from afar, underwater and amid debris, making them easier to find.
