PLANE – A detail that isn’t one. On January 6th a Boeing 737 MAX 9 has A door was lost at an altitude of 5000 meters. If other airlines using this model discovered poorly screwed bolts, many elements that could explain this terrible accident are missing. But the investigators encounter a major problem: the black box that plays back the conversations in the cockpit does not record anything, as you can see in our video above.
There are two types of black boxes on board every aircraft: one records flight data, the other records sounds in the cockpit. Collecting and then analyzing this data is critical for authorities investigating aviation accidents. However, the agency responsible for civil aviation in the United States, the Federal Aviation Administration (FAA), allows recorded cockpit conversations to be overwritten after two hours. Very often, investigators do not have access to the necessary voice data.
However, in Europe this recording time is 25 hours. In addition, the National Transportation Safety Board has been calling on the FAA for years to extend the registration period for all American aircraft. However, as Forbes points out, the FAA estimates that the renovation is too expensive at around $742 million. Instead, last November it proposed extending the registration deadline for new aircraft, a measure that would be implemented in early 2025.
To prevent black box data loss and facilitate accident investigations, other solutions have been proposed. Some suggest installing cameras in the cockpit to support the voice recorder, or even dematerializing the black box so that it can transmit flight data live, explains media agency AFAR. To see if the Boeing 737 MAX 9 near-tragedy will prompt the FAA to change the standards of all American black boxes.
