New information on aviation accident

Restos avionIn the process of deciphering information in the black boxes of the Boeing 737-200 that crashed in Havana last May, it has been possible to identify 100% of the technical parameters, Armando Daniel López, president of the Institute of Civil Aeronautics of Cuba (IACC), informed Granma.

However, it was not possible to identify all phrases and words in the audio box that records the cabin crew’s voices.

This process was carried out in laboratories in the United States and three Cuban specialists participated, in addition to a group of aeronautical inspectors from Mexico and the United States, who worked together.

At this time, IACC commissions continue to interpret the phrases recorded in the voice box, a deciphering process that is between 90 and 95% complete, although “with the amount of information obtained, we already know the behavior in cabin,” the official emphasized.

In a second stage of the investigation, the commission will work with the plane´s flight and operational parameters recorded in the black box (speed, height, rotation, power of the engines, among others) to develop a profile and graphic modeling of what occurred from the moment of takeoff to that of the accident.

At the same time, all parts, pieces, and aggregates of the aircraft are stored together in a warehouse where the aircraft’s different systems can be analyzed.

“This allows, in the first place, to determine if any of these components were damaged or affected before the plane hit the ground,” Daniel Lopez said.

Another approach that the Commission will use is to analyze the causes of all plane crashes involving this model of aircraft in other parts of the world, and compare the information with the incident in Havana, to find possible commonalities.

The investigative process is governed by a resolution established by the Minister of Transport. In addition, Annex 13 of the International Civil Aviation Organization outlines a total of 66 activities that must be completed step by step to produce an accident summary.

The country’s highest authorities, led by President Miguel Díaz-Canel Bermúdez, the Ministry of Transportation, and other bodies, are closely following the work being carried out, Daniel López added.

“This is an investigation that we cannot hurry, we owe our best professional effort to the families of the victims and our people,” he concluded.
